Release notes 26.7.0 (#893)
* Release notes for 26.7.0 New platform features. Discovered via Claude, using a generated script. This will later inform a skill. Note: It misses release note comments inside PR descriptions. Working on a fix. * Improve generated script It no longer tries to find the "release notes" since they are quite free form. Instead, an LLM can do that but after the script pulls the content. * Rearranged release notes after catching the missing release notes from issues. * remove a todo * nifi cold start * kafka pod FQDNs in cert DNs * TrustStore .spec.tlsPemCaName no configurable * NiFi 1 CRD fields gone, and sensitiveProperties removedl * Nifi OPA Authorizer thread exhaustion * Product changes Based on data in portal, but with a correction for Spark * docs: Tweak 26.7.0 release notes * docs: Fix underscore rendering issue * docs: Apply suggestions from review Co-authored-by: Lars Francke <lars.francke@stackable.tech> * docs: Apply suggestion from review * docs: Add vulnerabilities section * docs: Add Druid deprecation admonition * docs: Update getiing-started page * docs: Apply suggestions from review Co-authored-by: Lars Francke <lars.francke@stackable.tech> * docs: Fix two small typos * docs: Apply suggestions from review Co-authored-by: Lars Francke <lars.francke@stackable.tech> * docs: Move UIF timeout change to fixed section * docs: Mark Druid 37 TLS/S3 region changes as breaking * docs: Update order of breaking changes overview * docs: Use consistent name for UIF * docs: Add release highlights * docs: Apply suggestions from review Co-authored-by: Lars Francke <lars.francke@stackable.tech> * docs: Adjust Superset Celery query section * chore: Add missing colon * docs: Add links to product-specific upgrade guides * docs: Add examples of generic database connections * docs: Mark Kafka FQDN change as breaking * docs: Add SPDX SBOM entry * docs: Apply suggestion from review Co-authored-by: Lars Francke <lars.francke@stackable.tech> --------- Co-authored-by: Techassi <git@techassi.dev> Co-authored-by: Lars Francke <lars.francke@stackable.tech>

.Stackable support for Apache Druid is deprecated
11+
====
12+
Stackable's support for xref:druid:index.adoc[Apache Druid] is deprecated as of SDP link:#_release_26_7[26.7] and is planned for removal in SDP 27.11.
13+
This concerns only the Apache Druid integration in the Stackable Data Platform (SDP).
14+
Apache Druid itself is an independent, actively maintained project and is not affected; only its inclusion in the SDP is being discontinued.
15+
We have taken this decision because we have not seen adoption of Apache Druid among our customers.
16+
17+
The planned timeline is:
18+
19+
* SDP 26.7 ships Apache Druid link:#druid-37_0_0[37.0.0], the final LTS version we plan to provide, with approximately one year of support.
20+
* SDP 27.7 is planned to be the last release that includes Apache Druid.
21+
* Apache Druid is planned to be removed in SDP 27.11.
22+
23+
There is no direct replacement for Apache Druid within the SDP.
24+
If you rely on Apache Druid, please contact us via our https://stackable.tech/[homepage] or the https://github.com/orgs/stackabletech/discussions[Discussions forum] to discuss your options.
25+
If you are willing to fund its continued development and support, we are open to reconsidering this decision.
