CHANGELOG.md

# Changelog

All notable changes to this project will be documented in this file.

## [Unreleased]

### Added

- Add root descriptions to all CRDs defined in this crate (`AuthenticationClass`, `Listener`,
  `ListenerClass`, `PodListeners`, `S3Bucket`, `S3Connection`, `Scaler`), now that the `versioned`
  macro requires a `doc` argument ([#1228]).

[#1228]: https://github.com/stackabletech/operator-rs/pull/1228

## [0.112.0] - 2026-06-22

### Added

- Add `Client::{get_feature_gates,get_enabled_feature_gates,get_disabled_feature_gates}` associated
  functions to retrieve all, enabled, or disabled feature gates from the Kubernetes apiserver ([#1207], [#1208]).
- Add a new `v2` module that provides more type-safe variants of the existing functions ([#1225]).
- Add documentation for the `roleGroups` field, which now shows up as a description in the generated CRDs ([#1227]).

### Changed

- BREAKING: Use `serde_json::Value` instead of `String` for user-provided JSON `configOverrides`. This change is marked as breaking, as it causes a breaking change to the CRDs ([#1206]).

[#1225]: https://github.com/stackabletech/operator-rs/pull/1225
[#1227]: https://github.com/stackabletech/operator-rs/pull/1227

## [0.111.1] - 2026-04-28

### Added

- Derive `Clone` for `OperatorEnvironmentOptions` ([#1203]).

[#1203]: https://github.com/stackabletech/operator-rs/pull/1203

## [0.111.0] - 2026-04-27

### Added

- BREAKING: Add CLI argument and env var to set the image repository used to construct final product
  image names: `IMAGE_REPOSITORY` (`--image-repository`), eg. `oci.example.org/my/namespace` ([#1199]).

### Changed

- BREAKING: The product image selection mechanism via `ProductImage::resolve` now takes three
  parameters instead of two. The new parameters are: `image_name`, `image_repository`, and
  `operator_version` ([#1199]).

[#1199]: https://github.com/stackabletech/operator-rs/pull/1199

## [0.110.1] - 2026-04-16

### Added

- Derive `strum::AsRefStr` for `ClientAuthenticationMethod` ([#1197]).
- Add `DerbyConnection::jdbc_connection_details_for_network_access` helper ([#1200]).

[#1197]: https://github.com/stackabletech/operator-rs/pull/1197
[#1200]: https://github.com/stackabletech/operator-rs/pull/1200

## [0.110.0] - 2026-04-10

### Added

- Add generic database connection mechanism ([#1163]).
- Add `config_overrides` module with `KeyValueOverridesProvider` trait, enabling
  structured config file formats (e.g. JSON) in addition to key-value overrides ([#1177]).
- Add `Scaler` CRD ([#1190], [#1195]).

### Changed

- BREAKING: Change signature of `ContainerBuilder::add_env_vars` from `Vec<EnvVar>` to `IntoIterator<Item = EnvVar>` ([#1163]).
- BREAKING: Remove `EXPERIMENTAL_` prefix in `CONFIG_OVERRIDE_FILE_HEADER_KEY` and `CONFIG_OVERRIDE_FILE_FOOTER_KEY` ([#1191]).
- BREAKING: Bump `kube` from a custom version (`fe69cc486ff8e62a7da61d64ec3ebbd9e64c43b5`, which is between `3.0.1` and `3.1.0`
  and was needed to pull in schema fixes) to `3.1.0`. This means that the CRD schema generation bugs
  [#1934](https://github.com/kube-rs/kube/pull/1934) and [#1942](https://github.com/kube-rs/kube/pull/1942) are fixed ([#1192]).
- BREAKING: Add `ConfigOverrides` type parameter to `CommonConfiguration`, `Role` and `RoleGroup`.
  The `config_overrides` field is now generic instead of `HashMap<String, HashMap<String, String>>` ([#1177]).
- BREAKING: In [#1178] the `clientAuthenticationMethod` was added to the `ClientAuthenticationOptions` struct,
  resulting it to show up in all product CRDs. even those that don't support configuring the client authentication method.
  With this change, operators need to opt-in to the `clientAuthenticationMethod` field by using the new
  `ClientAuthenticationMethodOption` struct for the generic type `ProductSpecificClientAuthenticationOptions` on
  `ClientAuthenticationOptions`. That way the struct definitions (as well as docs etc.) remain in stackable-operator,
  but operators can decide if they want to offer support for this field or not ([#1194]).

[#1195]: https://github.com/stackabletech/operator-rs/pull/1195

## [0.109.0] - 2026-04-07

### Added

- Git sync: add support for CAs ([#1154]).
- Add support for specifying a `clientAuthenticationMethod` for OIDC ([#1178]).
  This was originally done in [#1158] and had been reverted in [#1170].
- Implement `Deref` for `kvp::Key` to be more ergonomic to use ([#1182]).
- Add `create_random_secret_if_not_exists` function, which create a random Secret in case it doesn't already exist.
  It notably also fixes a bug we had in trino and airflow-operator, where we created immutable Secrets,
  which lead to problems ([#1187]).

### Changed

- Bump stackable-versioned to `0.9.0`, refer to its [changelog](../stackable-versioned/CHANGELOG.md) ([#1189]).
- Bump stackable-webhook to `0.9.1`, refer to its [changelog](../stackable-webhook/CHANGELOG.md) ([#1189]).
- BREAKING: Add mandatory `provision_parts` argument to `SecretOperatorVolumeSourceBuilder::new` ([#1165]).
  It now forces the caller to make an explicit choice if the public parts are sufficient or if private
  (e.g. a certificate for the Pod) parts are needed as well. This is done to avoid accidentally requesting
  too much parts. For details see [this issue](https://github.com/stackabletech/issues/issues/547).

  Additionally, `SecretClassVolume::to_volume` and `SecretClassVolume::to_ephemeral_volume_source`
  also take the same new argument.
- BREAKING: `OpaConfig::full_document_url` now takes `&OpaApiVersion` instead of `OpaApiVersion` ([#1186]).
- BREAKING: `EndOfSupportChecker::new` now takes `&EndOfSupportOptions` instead of `EndOfSupportOptions` ([#1186]).
- BREAKING: `Labels::recommended` now takes `&ObjectLabels<R>` instead of `ObjectLabels<R>` ([#1186]).
- BREAKING: `transform_all_roles_to_config` now takes `&HashMap<..., S>` by reference and requires generic `S: BuildHasher` ([#1186]).
- BREAKING: `env_vars_from_rolegroup_config` now requires generic `S: BuildHasher` for the HashMap parameter ([#1186]).
- BREAKING: `FromFragment` impl for `HashMap` now requires `S: BuildHasher + Default` ([#1186]).
- BREAKING: `Merge` impl for `HashMap` now requires `S: BuildHasher` ([#1186]).

### Removed

- BREAKING: Remove unused `add_prefix`, `try_add_prefix`, `set_name`, and `try_set_name` associated
  functions from `kvp::Key` to disallow mutable access to inner values ([#1182]).

[#1154]: https://github.com/stackabletech/operator-rs/pull/1154

[#1189]: https://github.com/stackabletech/operator-rs/pull/1189

## [0.108.0] - 2026-03-10

### Removed

- Reverted support for specifying a `clientAuthenticationMethod` for OIDC ([#1170]).
  It can be added back after the SDP 26.3.0 release.

[#1170]: https://github.com/stackabletech/operator-rs/pull/1170

## [0.107.1] - 2026-03-10

### Added

- Add CRD established signal/helper ([#1167]).

[#1167]: https://github.com/stackabletech/operator-rs/pull/1167
[#1168]: https://github.com/stackabletech/operator-rs/pull/1168

## [0.107.0] - 2026-03-09

### Added

- Add support for specifying a `clientAuthenticationMethod` for OIDC ([#1158]).
- Added two new crate features: `crds` and `kube-ws` ([#1162]).

### Fixed

- BREAKING: Fix compilation failures when not enabling default features ([#1162]).
  This is achieved by removing the `clap`, `telemetry` and `versioned` features, which were previously enabled by default.
  They have been removed as the stackable-operator code actually always requires them.

[#1158]: https://github.com/stackabletech/operator-rs/pull/1158
[#1162]: https://github.com/stackabletech/operator-rs/pull/1162

## [0.106.2] - 2026-02-26

[#1151]: https://github.com/stackabletech/operator-rs/pull/1151

## [0.105.0] - 2026-02-03

### Added

- BREAKING: Add support to gracefully shutdown `EosChecker`.
  `EosChecker::run` now requires passing a shutdown signal, which is any `Future<Output = ()>` ([#1146]).
- Add `SignalWatcher` which can be used to watch signals and multiply them to gracefully shutdown
  multiple concurrent tasks/futures ([#1147]).

[#1146]: https://github.com/stackabletech/operator-rs/pull/1146
[#1147]: https://github.com/stackabletech/operator-rs/pull/1147

## [0.103.0] - 2026-01-16

### Changed

- BREAKING: Add support for the SSH protocol for pulling git content ([#1121]).
  This is a user-facing breaking change and should also be highlighted by operators using this functionality.

[#1121]: https://github.com/stackabletech/operator-rs/pull/1121

## [0.102.0] - 2026-01-14

### Added

- BREAKING: Add `objectOverrides` field to `ListenerSpec` ([#1136]).

### Changed

- Revert and pin k8s-openapi to 0.26.0 ([#1135]).
- BREAKING: `ListenerSpec` no longer derives `Eq` ([#1136]).

[#1135]: https://github.com/stackabletech/operator-rs/pull/1135
[#1136]: https://github.com/stackabletech/operator-rs/pull/1136
[#1139]: https://github.com/stackabletech/operator-rs/pull/1139

## [0.101.2] - 2026-01-07

### Changed

- Bump stackable-webhook to 0.8.1, refer to its [changelog](../stackable-webhook/CHANGELOG.md) ([#1134]).

[#1134]: https://github.com/stackabletech/operator-rs/pull/1134

## [0.101.1] - 2025-12-23

### Fixed

- BREAKING: Only take `object_overrides` by reference in `ClusterResources::new` ([#1132]).

[#1132]: https://github.com/stackabletech/operator-rs/pull/1132

## [0.101.0] - 2025-12-23

### Added

- Support `objectOverrides`, a list of generic Kubernetes objects, which are merged into the objects created by the operator.
  Alongside, a `deep_merger` module was added, which takes a Kubernetes object and a list of overrides and merges them into the provided object ([#1118]).

### Changed

- Bump stackable-webhook to 0.8.0, refer to its [changelog](../stackable-webhook/CHANGELOG.md) ([#1117]).
- BREAKING: `ClusterResources` now requires the objects added to implement `DeepMerge`.
  This is very likely a stackable-operator internal change, but technically breaking ([#1118]).
- Depend on the patched version of kube-rs available at <https://github.com/stackabletech/kube-rs>,
  ensuring the operators automatically benefit from the fixes ([#1124]).

### Removed

- BREAKING: `ClusterResources` no longer derives `Eq` ([#1118]).

[#1118]: https://github.com/stackabletech/operator-rs/pull/1118

  This is only breaking if default features for `stackable-operator` are disabled ([#1096]).
- BREAKING: Bump `product-config` to 0.8.0 ([#1098]).

[#1096]: https://github.com/stackabletech/operator-rs/pull/1096

## [0.98.0] - 2025-09-22

### Added

- Extend `ObjectMetaBuilder` with `finalizers` ([#1094]).

### Changed

- BREAKING: Upgrade to `schemars` 1.0, `kube` 2.0 and `k8s-openapi` 0.26 (using Kubernetes 1.34) ([#1091]).

### Fixed

- BREAKING: Don't allow uppercase characters in Kubernetes object names ([#1095]).

[#1091]: https://github.com/stackabletech/operator-rs/pull/1091
[#1094]: https://github.com/stackabletech/operator-rs/pull/1094
[#1095]: https://github.com/stackabletech/operator-rs/pull/1095

## [0.97.0] - 2025-09-09

### Added

- BREAKING: Add a new CLI flag/env to disabling CRD maintenance: `--disable-crd-maintenance` ([#1085]).

### Removed

- BREAKING: Remove the Merge implementation for PodTemplateSpec ([#1087]).
  It was broken because the instance was overridden by the given defaults.
  This function is not used by the Stackable operators.

### Fixed

- Don't default the `termination_grace_period` of the `ProbeBuilder` to 0, as this is an invalid value ([#1090]).

[#1085]: https://github.com/stackabletech/operator-rs/pull/1085
[#1087]: https://github.com/stackabletech/operator-rs/pull/1087
[#1090]: https://github.com/stackabletech/operator-rs/pull/1090

## [0.96.0] - 2025-08-25

### Added

- Add a `cli::CommonOptions` struct, which can be used for non-operator Stackable tools ([#1083]).

### Changed

- BREAKING: The `telemetry` and `cluster_info` fields of `ProductOperatorRun` have moved below the `common` field ([#1083]).

[#1083]: https://github.com/stackabletech/operator-rs/pull/1083

## [0.95.1] - 2025-08-21

### Fixed

- Derive `Clone` for `ProbeBuilder` and `ProbeAction` ([#1082]).

[#1082]: https://github.com/stackabletech/operator-rs/pull/1082

## [0.95.0] - 2025-08-21

### Added

- Add `ProbeBuilder` to build Kubernetes container probes ([#1078]).
- Re-export `stackable-certs` and `stackable-webhook` crates ([#1074]).
- BREAKING: Add two new required CLI arguments: `--operator-namespace` and `--operator-service-name`.
  These two values are used to construct the service name in the CRD conversion webhook ([#1066]).
- Re-export `stackable-certs` and `stackable-webhook` crates ([#1074]).

### Changed

- BREAKING: The `ResolvedProductImage` field `app_version_label` was renamed to `app_version_label_value` to match changes to its type ([#1076]).
- BREAKING: Rename two fields of the `ProductOperatorRun` struct for consistency and clarity ([#1066]):
  - `telemetry_arguments` -> `telemetry`
  - `cluster_info_opts` -> `cluster_info`
- BREAKING: Some modules have been moved into the `stackable-shared` crate, so that they can also be
  used in `stackable-certs` and `stackable-webhook` ([#1074]):
  - The module `stackable_operator::time` has moved to `stackable_operator::shared::time`
  - The module `stackable_operator::commons::secret` has moved to `stackable_operator::shared::secret`

### Fixed

- BREAKING: Fix bug where `ResolvedProductImage::app_version_label` could not be used as a label value because it can contain invalid characters.
  This is the case when referencing custom images via a `@sha256:...` hash. As such, the `product_image_selection::resolve` function is now fallible ([#1076]).

## [0.94.0] - 2025-07-10

### Added

- The default Kubernetes cluster domain name is now fetched from the kubelet API unless explicitly configured ([#1068], [#1071])
  This requires operators to have the RBAC permission to `get` `nodes/proxy` in the apiGroup "", an example RBAC rule could look like:

  ```yaml
  ---
  apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: operator-cluster-role
  rules:
    - apiGroups: [""]
      resources: [nodes/proxy]
      verbs: [get]
  ```

  In addition, they must be provided the environment variable `KUBERNETES_NODE_NAME` like this:

  ```yaml
  env:
  - name: KUBERNETES_NODE_NAME
    valueFrom:
      fieldRef:
        fieldPath: spec.nodeName
  ```

- Add associated functions on `RoleGroupRef` to return the rolegroup headless and metrics service name ([#1069]).

### Changed

- Update `kube` to `1.1.0` ([#1049]).
- BREAKING: Return type for `ListenerOperatorVolumeSourceBuilder::new()` is no longer a `Result` ([#1058]).

### Fixed

- Allow uppercase characters in domain names ([#1064]).

### Removed

- BREAKING: Removed `last_update_time` from CRD ClusterCondition status ([#1054]).
- BREAKING: Removed role binding to legacy service accounts ([#1060]).

## [0.93.0] - 2025-05-19

### Changed

- BREAKING: Version common CRD structs and enums ([#968]).
  - All CRD-related types and function now reside in the `stackable_operator::crd` module.
  - Each CRD-related struct and enum has been versioned. The initial version is `v1alpha1`.
  - The `static` authentication provider must now be imported using `r#static`.
  - Import are now more granular in general.
- BREAKING: Update to `kube` to `1.0.0` and `k8s-openapi` to `0.25.0`.
  Use k8s `1.33` for compilation ([#1037]).
- Separate some developer docs from CRD descriptions ([#1040]).

### Fixed

- Re-export versioned CRD-specific error types ([#1025]).

### Changed

- BREAKING: Remove `cli::TelemetryArguments` and `cli::RollingPeriod` which are both replaced by
  types from `stackable_telemetry` ([#1001]).
- BREAKING: The `ProductOperatorRun` struct now uses `stackable_telemetry::tracing::TelemetryOptions`
  for the `telemetry_arguments` field ([#1001]).

[#1001]: https://github.com/stackabletech/operator-rs/pull/1001

## [0.90.0] - 2025-04-07

[#977]: https://github.com/stackabletech/operator-rs/pull/977

## [0.88.0] - 2025-04-02

### Added

- Add Deployments to `ClusterResource`s ([#992]).
- Add `DeploymentConditionBuilder` ([#993]).

### Changed

[#993]: https://github.com/stackabletech/operator-rs/pull/993

## [0.87.5] - 2025-03-19

### Fixed

- Enable the `kube/ring` feature to use ring as the crypto provider for `rustls`. This will
  otherwise cause runtime errors which result in panics ([#988]).

## [0.87.4] - 2025-03-17

### Changed

- Bump `kube` to 0.99.0 and `json-patch` to 4.0.0 ([#982]).

[#982]: https://github.com/stackabletech/operator-rs/pull/982

## [0.87.3] - 2025-03-14

### Added

- Add a `Region::is_default_config` function to determine if a region sticks to the default config ([#983]).

[#983]: https://github.com/stackabletech/operator-rs/pull/983

## [0.87.2] - 2025-03-10

### Changed

- Make `region.name` field in in S3ConnectionSpec public ([#980]).

[#980]: https://github.com/stackabletech/operator-rs/pull/980

## [0.87.1] - 2025-03-10

### Changed

- Refactor `region` field in S3ConnectionSpec ([#976]).

[#976]: https://github.com/stackabletech/operator-rs/pull/976

## [0.87.0] - 2025-02-28

### Changed

- BREAKING: Update `strum` to `0.27.1` (clients need to also update strum!), `rand` to `0.9.0` and `convert_case` to `0.8.0` ([#972]).

[#972]: https://github.com/stackabletech/operator-rs/pull/972

## [0.86.2] - 2025-02-21

### Fix

- BREAKING: Improve `AwsRegion::name()` ergonomics: borrow self and return `Option<&str>` ([#963]).

[#963]: https://github.com/stackabletech/operator-rs/pull/963

## [0.86.1] - 2025-02-21

### Added

- BREAKING: Add `region` field to S3ConnectionSpec (defaults to `us-east-1`) ([#959]).

[#959]: https://github.com/stackabletech/operator-rs/pull/959

## [0.86.0] - 2025-01-30

### Added

- Add generic `TtlCache` structure as well as a `UserInformationCache` type ([#943]).

[#943]: https://github.com/stackabletech/operator-rs/pull/943

## [0.85.0] - 2025-01-28

### Changed

- Change constant used for product image selection so that it defaults to OCI ([#945]).

[#945]: https://github.com/stackabletech/operator-rs/pull/945

## [0.84.1] - 2025-01-22

### Fixed

- Remove `Merge` trait bound from `erase` and make `product_specific_common_config` public ([#946]).
- BREAKING: Revert the change of appending a dot to the default cluster domain to make it a FQDN, it is now `cluster.local` again. Users can instead explicitly opt-in to FQDNs via the ENV variable `KUBERNETES_CLUSTER_DOMAIN`. ([#947]).

[#946]: https://github.com/stackabletech/operator-rs/pull/946
[#947]: https://github.com/stackabletech/operator-rs/pull/947

## [0.84.0] - 2025-01-16

### Added

- BREAKING: Aggregate emitted Kubernetes events on the CustomResources thanks to the new
  [kube feature](https://github.com/kube-rs/controller-rs/pull/116). Instead of reporting the same
  event multiple times it now uses `EventSeries` to aggregate these events to single entry with an
  age like `3s (x11 over 53s)` ([#938]):
  - The `report_controller_error` function now needs to be async.
  - It now takes `Recorder` as a parameter instead of a `Client`.
  - The `Recorder` instance needs to be available across all `reconcile` invocations, to ensure
    aggregation works correctly.
  - The operator needs permission to `patch` events (previously only `create` was needed).
- Add `ProductSpecificCommonConfig`, so that product operators can have custom fields within `commonConfig`.
  Also add a `JavaCommonConfig`, which can be used by JVM-based tools to offer `jvmArgumentOverrides` with this mechanism ([#931])

### Changed

- BREAKING: Bump Rust dependencies to enable Kubernetes 1.32 (via `kube` 0.98.0 and `k8s-openapi` 0.23.0) ([#938]).
- BREAKING: Append a dot to the default cluster domain to make it a FQDN and allow FQDNs when validating a `DomainName` ([#939]).

[#931]: https://github.com/stackabletech/operator-rs/pull/931
[#938]: https://github.com/stackabletech/operator-rs/pull/938
[#939]: https://github.com/stackabletech/operator-rs/pull/939

## [0.83.0] - 2024-12-03

### Added

- Added cert lifetime setter to `SecretOperatorVolumeSourceBuilder` ([#915])

### Changed

- Replace unmaintained `derivative` crate with `educe` ([#907]).
- Bump dependencies, notably rustls 0.23.15 to 0.23.19 to fix [RUSTSEC-2024-0399] ([#917]).

[RUSTSEC-2024-0399]: https://rustsec.org/advisories/RUSTSEC-2024-0399

## [0.82.0] - 2024-11-23

### Fixed

- Fixed URL handling related to OIDC and `rootPath` with and without trailing slashes. Also added a bunch of tests ([#910]).

### Changed

- BREAKING: Made `DEFAULT_OIDC_WELLKNOWN_PATH` private. Use `AuthenticationProvider::well_known_config_url` instead ([#910]).
- BREAKING: Changed visibility of `commons::rbac::service_account_name` and `commons::rbac::role_binding_name` to
  private, as these functions should not be called directly by the operators. This is likely to result in naming conflicts
  as the result is completely dependent on what is passed to this function. Operators should instead rely on the roleBinding
  and serviceAccount objects created by `commons::rbac::build_rbac_resources` and retrieve the name from the returned
  objects if they need it ([#909]).
- Changed the names of the objects that are returned from `commons::rbac::build_rbac_resources` to not rely solely on the product
  they refer to (e.g. "nifi-rolebinding") but instead include the name of the resource to be unique per cluster
  (e.g. simple-nifi-rolebinding) ([#909]).

[#909]: https://github.com/stackabletech/operator-rs/pull/909
[#910]: https://github.com/stackabletech/operator-rs/pull/910

## [0.81.0] - 2024-11-05

### Added

- Add new `PreferredAddressType::HostnameConservative` ([#903]).

### Changed

- BREAKING: Split `ListenerClass.spec.preferred_address_type` into a new `PreferredAddressType` type. Use `resolve_preferred_address_type()` to access the `AddressType` as before ([#903]).

[#903]: https://github.com/stackabletech/operator-rs/pull/903

## [0.80.0] - 2024-10-23

### Changed

- BREAKING: Don't parse `/etc/resolv.conf` to auto-detect the Kubernetes cluster domain in case it is not explicitly configured.
  Instead the operator will default to `cluster.local`. We revert this now after some concerns where raised, we will
  create a follow-up decision instead addressing how we will continue with this ([#896]).
- Update Rust dependencies (Both `json-patch` and opentelemetry crates cannot be updated because of conflicts) ([#897]):
  - Bump `kube` to `0.96.0`,
  - `rstest` to `0.23.0` and
  - `tower-http` to `0.6.1`

### Fixed

- Fix Kubernetes cluster domain parsing from resolv.conf, e.g. on AWS EKS.
  We now only consider Kubernetes services domains instead of all domains (which could include non-Kubernetes domains) ([#895]).

[#895]: https://github.com/stackabletech/operator-rs/pull/895
[#896]: https://github.com/stackabletech/operator-rs/pull/896
[#897]: https://github.com/stackabletech/operator-rs/pull/897

## [0.79.0] - 2024-10-18

### Added

- Re-export the `YamlSchema` trait and the `stackable-shared` crate as the `shared` module ([#883]).
- BREAKING: Added `preferredAddressType` field to ListenerClass CRD ([#885]).
- BREAKING: The cluster domain (default: `cluster.local`) can now be configured in the individual
  operators via the ENV variable `KUBERNETES_CLUSTER_DOMAIN` or resolved automatically by parsing
  the `/etc/resolve.conf` file. This requires using `initialize_operator` instead of `create_client`
  in the `main.rs` of the individual operators ([#893]).

### Changed

- BREAKING: The `CustomResourceExt` trait is now re-exported from the `stackable-shared` crate. The
  trait functions use the same parameters but return a different error type ([#883]).
- BREAKING: `KeyValuePairs` (as well as `Labels`/`Annotations` via it) is now backed by a `BTreeMap`
  rather than a `BTreeSet` ([#888]).
  - The `Deref` impl now returns a `BTreeMap` instead.
  - `iter()` now clones the values.

### Fixed

- BREAKING: `KeyValuePairs::insert` (as well as `Labels::`/`Annotations::` via it) now overwrites
  the old value if the key already exists. Previously, `iter()` would return _both_ values in
  lexicographical order (causing further conversions like `Into<BTreeMap>` to prefer the maximum
  value) ([#888]).

### Removed

- BREAKING: The `CustomResourceExt` trait doesn't provide a `generate_yaml_schema` function any
  more. Instead, use the high-level functions to write the schema to a file, write it to stdout or
  use it as a `String` ([#883]).

## [0.78.0] - 2024-09-30

### Added

- Add Kerberos AuthenticationProvider ([#880]).

[#880]: https://github.com/stackabletech/operator-rs/pull/880

## [0.77.1] - 2024-09-27

### Fixed

- Fix always returning an error stating that volumeMounts are colliding. Instead move the error
  creation to the correct location within an `if` statement ([#879]).

[#879]: https://github.com/stackabletech/operator-rs/pull/879

## [0.77.0] - 2024-09-26

### Fixed

- Fix the logback configuration for logback versions from 1.3.6/1.4.6 to 1.3.11/1.4.11 ([#874]).
- BREAKING: Avoid colliding volumes and mounts by only adding volumes or mounts if they do not already exist. This makes functions such as `PodBuilder::add_volume` or `ContainerBuilder::add_volume_mount` as well as related ones fallible ([#871]).

### Changed

- BREAKING: Remove the `unique_identifier` argument from `ResolvedS3Connection::add_volumes_and_mounts`, `ResolvedS3Connection::volumes_and_mounts` and `ResolvedS3Connection::credentials_mount_paths` as it is not needed anymore ([#871]).

[#871]: https://github.com/stackabletech/operator-rs/pull/871
[#874]: https://github.com/stackabletech/operator-rs/pull/874

## [0.76.0] - 2024-09-19

### Added

- BREAKING: Add `HostName` type and use it within LDAP and OIDC AuthenticationClass as well as S3Connection ([#863]).

### Changed

- BREAKING: The TLS verification struct now resides in the `commons::tls_verification` module, instead of being placed below `commons::authentication::tls` ([#863]).
- BREAKING: Rename the `Hostname` type to `DomainName` to be consistent with RFC 1123 ([#863]).

### Fixed

- BREAKING: The fields `bucketName`, `connection` and `host` on `S3BucketSpec`, `InlinedS3BucketSpec` and `S3ConnectionSpec` are now mandatory. Previously operators errored out in case these fields where missing ([#863]).

[#863]: https://github.com/stackabletech/operator-rs/pull/863

## [0.75.0] - 2024-09-19

### Added

- Add `Hostname` and `KerberosRealmName` types extracted from secret-operator ([#851]).
- Add support for listener volume scopes to `SecretOperatorVolumeSourceBuilder` ([#858]).

### Changed

- BREAKING: `validation` module now uses typed errors ([#851]).
- Set `checkIncrement` to 5 seconds in Logback config ([#853]).
- Bump Rust dependencies and enable Kubernetes 1.31 (via `kube` 0.95.0) ([#867]).

### Fixed

- Fix the CRD description of `ClientAuthenticationDetails` to not contain internal Rust doc, but a public CRD description ([#846]).
- `StackableAffinity` fields are no longer erroneously marked as required ([#855]).
- BREAKING: `ClusterResources` will now only consider deleting objects that are marked as directly owned (via `.metadata.ownerReferences`) ([#862]).

## [0.74.0] - 2024-08-22

### Added

- Add `iter::reverse_if` helper ([#838]).
- Add two new constants `CONFIG_OVERRIDE_FILE_HEADER_KEY` and `CONFIG_OVERRIDE_FILE_FOOTER_KEY` ([#843]).

### Changed

- BREAKING: Replace `lazy_static` with `std::cell::LazyCell` (the original implementation was done in [#827] and reverted in [#835]) ([#840]).
- BREAKING: Swap priority order of role group config and role overrides in configuration merging to prioritize overrides in general ([#841]).

## [0.73.0] - 2024-08-09

### Added

- Rollout tracker for `StatefulSet` ([#833]).

### Changed

- Reverted [#827], in order to restore Rust 1.79 compatibility for now ([#835]), re-opened in ([#840]).

### Fixed

- Invalid CRD schema for `StackableAffinity` contents. This was caused by the fields being optional and defaulting to `null`, while the custom schema marked the field as required ([#836]).

[#833]: https://github.com/stackabletech/operator-rs/pull/833
[#835]: https://github.com/stackabletech/operator-rs/pull/835
[#836]: https://github.com/stackabletech/operator-rs/pull/836

## [0.72.0] - 2024-08-05

### Changed

- BREAKING: Replace `lazy_static` with `std::cell::LazyCell` ([#827], [#835], [#840]).
- BREAKING: Convert `podOverrides` and `affinity` fields to take any arbitrary
  YAML input, rather than using the underlying schema. With this change, one of
  the larger CRDs, like the Druid CRD went down in size from `2.4MB` to `288K`
  (a 88% reduction). One downside is that user input is not checked to be a
  valid `PodTemplateSpec`, `PodAffinity`, `PodAntiAffinity` and `NodeAffinity`
  any more. However, checks can be re-added by using validation webhooks if
  needed. This change should not be breaking for the user and is a preparation
  for CRD versioning. ([#821]).

[#821]: https://github.com/stackabletech/operator-rs/pull/821
[#827]: https://github.com/stackabletech/operator-rs/pull/827

## [0.71.0] - 2024-07-29

### Added

- Added `ProductImage::product_version` utility function ([#817], [#818])

### Changed

- BREAKING: Bump `kube` to 0.92.0. This required changes in a unit test, because
  the `kube::runtime::watcher::Event` enum introduced new and renamed some
  variants. Also see the following additional resources ([#804]).
  - [Blog Post - Breaking Change](https://kube.rs/blog/2024/06/11/watcher-memory-improvements/#breaking-change)
  - [kube#1494](https://github.com/kube-rs/kube/pull/1494)

- Upgrade opentelemetry crates ([#811]).
- Bump rust-toolchain to 1.79.0 ([#822]).

### Fixed

- Product image selection pull request version override now only applies to pull requests ([#812]).
- OPA bundle builder logs without a log message are marked with the
  error "Message not found." instead of "Log event not parsable" ([#819]).

## [0.67.0] - 2024-04-25

### Changed

- Bump kube to 0.89.0 and update all dependencies ([#762]).
- BREAKING: Bump k8s compilation version to `1.29`. Also bump all dependencies.
  There are some breaking changes in k8s-openapi, e.g. PVCs now have `VolumeResourceRequirements` instead of `ResourceRequirements`,
  and `PodAffinityTerm` has two new fields `match_label_keys` and `mismatch_label_keys` ([#769]).

### Removed

[#725]: https://github.com/stackabletech/operator-rs/pull/725
[#728]: https://github.com/stackabletech/operator-rs/pull/728

## [0.62.0] - 2024-01-19

[#721]: https://github.com/stackabletech/operator-rs/pull/721

## [0.61.0] - 2024-01-15

### Added

- Add `TryFrom<[(K, V); N]>` implementation for `Annotations` and `Labels` ([#711]).
- Add `parse_insert` associated function for `Annotations` and `Labels` ([#711]).
- Add generic types for `TryFrom<BTreeMap<K, V>>` impl ([#714]).

- Add `TryFromIterator` impl for `Labels` and `Annotations` ([#715]).

### Changed

- Adjust `try_insert` for `Annotations` and `Labels` slightly ([#711]).

[#715]: https://github.com/stackabletech/operator-rs/pull/715

## [0.60.1] - 2024-01-04

### Fixed

- Let `ldap::AuthenticationProvider::add_volumes_and_mounts` also add the needed TLS volumes. This functionality was removed in [#680] and causes kuttl tests to fail, as the ca-cert volume and mount where missing. This patch restores the previous behavior (of adding needed TLS volumes) ([#708]).

[#708]: https://github.com/stackabletech/operator-rs/pull/708

## [0.60.0] - 2024-01-03

### Added

- Add LDAP AuthenticationClassProvider `endpoint_url()` method so each operator doesn't have to construct it. ([#705])

[#705]: https://github.com/stackabletech/operator-rs/pull/705

## [0.59.0] - 2023-12-21 🌲

### Added

- Add `stackble_operator::kvp` module and types to allow validated construction of key/value pairs, like labels and
  annotations. Most users want to use the exported type aliases `Label` and `Annotation` ([#684]).

### Changed

- Move `stackable_operator::label_selector::convert_label_selector_to_query_string` into `kvp` module. The conversion
  functionality now is encapsulated in a new trait `LabelSelectorExt`. An instance of a `LabelSelector` can now be
  converted into a query string by calling the associated function `ls.to_query_string()` ([#684]).
- BREAKING: Remove legacy node selector on `RoleGroup` ([#652]).

[#684]: https://github.com/stackabletech/operator-rs/pull/684
[#652]: https://github.com/stackabletech/operator-rs/pull/652

## [0.58.1] - 2023-12-12

### Added

- More CRD documentation ([#697]).

[#697]: https://github.com/stackabletech/operator-rs/pull/697

## [0.58.0] - 2023-12-04

### Added

- Add `oidc::AuthenticationProvider`. This enables users to deploy a new `AuthenticationClass` for OIDC providers like
  Keycloak, Okta or Auth0 ([#680]).
- Add a common `ClientAuthenticationDetails` struct, which provides common fields and functions to specify
  authentication options on product cluster level. Additionally, the PR also adds `ClientAuthenticationConfig`,
  `oidc::ClientAuthenticationOptions`, and `ldap::ClientAuthenticationOptions` ([#680]).

### Changed

- BREAKING: Change the naming of all authentication provider structs. It is now required to import them using the
  module. So imports change from `...::authentication::LdapAuthenticationProvider` to
  `...::authentication::ldap::AuthenticationProvider` for example ([#680]).
- BREAKING: Move TLS related structs into the `tls` module. Imports need to be adjusted accordingly ([#680]).

### Fixed

- Fixed appVersion label in case container images contain a hash, such as `docker.stackable.tech/stackable/nifi@sha256:85fa483aa99b9997ce476b86893ad5ed81fb7fd2db602977eb8c42f76efc109`. Also added a test-case to ensure we support images containing hashes. This should be a rather cosmetic fix, images with hashes should have worked before anyway ([#690]).

[#680]: https://github.com/stackabletech/operator-rs/pull/680
[#690]: https://github.com/stackabletech/operator-rs/pull/690

## [0.57.0] - 2023-12-04

### Changed

- BREAKING: The `CustomResourceExt` functions now take the Operator version as an argument.
  It replaces `DOCS_BASE_URL_PLACEHOLDER` in doc strings with a link to URL base, so
  `DOCS_BASE_URL_PLACEHOLDER/druid/` turns into `https://docs.stackable.tech/home/nightly/druid/`
  in the nightly operator ([#689]).

[#689]: https://github.com/stackabletech/operator-rs/pull/689

## [0.56.2] - 2023-11-23

### Added

- More documentation for CRD structs ([#687]).

## [0.56.1] - 2023-11-23

### Changed

- Update `kube` to `0.87.1` as version `0.86.0` was yanked ([#685]).

[#685]: https://github.com/stackabletech/operator-rs/pull/685

## [0.56.0] - 2023-10-31 👻

### Added

- Added `COMMON_BASH_TRAP_FUNCTIONS`, which can be used to write a Vector shutdown trigger file after the main
  application stopped ([#681]).

### Changed

- BREAKING: Rename `product_logging::framework::shutdown_vector_command` to `create_vector_shutdown_file_command` and
  added `remove_vector_shutdown_file_command` ([#681]).
- BREAKING: Remove re-export of `product_config`, update `product_config` to `0.6.0` ([#682]).

### Fixed

- Fix Docker image tag parsing when user specifies custom image ([#677]).

[#677]: https://github.com/stackabletech/operator-rs/pull/677
[#681]: https://github.com/stackabletech/operator-rs/pull/681
[#682]: https://github.com/stackabletech/operator-rs/pull/682

## [0.55.0] - 2023-10-16

### Added

- Mark the following functions as `const` ([#674]):
  - `ClusterResourceApplyStrategy::delete_orphans`
  - `LdapAuthenticationProvider::default_port`
  - `LdapAuthenticationProvider::use_tls`
  - `ListenerSpec::default_publish_not_ready_addresses`

  - `MemoryQuantity::from_gibi`
  - `MemoryQuantity::from_mebi`
  - `ClusterCondition::is_good`
  - `ClusterOperationsConditionBuilder::new`
  - `commons::pdb::default_pdb_enabled`
- Add interoperability between the `time` crate and the `stackable_operator::time::Duration` struct. This is opt-in and
  requires the `time` feature to be enabled. Additionally, adds `Add`, `AddAssign`, `Sub`, and `SubAssign` operations
  between `Duration` and `std::time::Instant`. Further adds a new helper function `Duration::now_utc` which calculates
  the duration from the unix epoch (1970-01-01 00:00:00) until now ([#671]).

### Changed

- BREAKING: Rename top-level `duration` module to `time`. Imports now use `stackable_operator::time::Duration` for
  example ([#671]).
- Convert the format of the Vector configuration from TOML to YAML ([#670]).
- BREAKING: Rename `PodBuilder::termination_grace_period_seconds` to `termination_grace_period`, and change it to take `Duration` struct ([#672]).

### Fixed

- stackable-operator-derive: Add descriptions to derived Fragment structs ([#675]).

  be compatible with Vector version 0.31.0. The product image must
  contain Vector 0.31.x ([#625]).

### Fixed

- Fix the log level filter for the Vector container. If the level of the
  ROOT logger was set to TRACE and the level of the file logger was set
  to DEBUG then TRACE logs were written anyway ([#625]).
