v1.2.0 Raw EventStreams

Breaking changes:

• scanConsumers() now returns parsed consumer descriptors ({ name, stream, identifier }) instead of filename strings.
• Stream/type names produced via typeAccessor are validated more strictly; invalid names (for example with whitespace) now fail fast.

New in 1.2:

• Raw EventStreams (raw=true) across stream/category/query APIs, emitting NDJSON Buffer chunks for zero-deserialization transport paths.
• Raw predicates and object matchers for byte-level filtering, plus fixes for NDJSON/raw behavior in EventStream and JoinEventStream.
• Read-path performance and correctness improvements (readRange, merge/backwards iteration fixes, index sync optimization, partition identifier caching).
• Consumer lifecycle improvements (in-memory registry lookup, progress events).

• feat: DCB support via CommitCondition API, query() improvements, and typeAccessor string path by @Copilot in #304
• feat(Storage): async partition + index scan in open() with 'opened' event and callback hook by @Copilot in #303

Full Changelog: v1.0.0...v1.1.0

v1.0.0 Switch to ESM

This only contains a shift from old CJS to ESM exports. It is otherwise functionally equivalent to 0.9.1

v0.9.1 Fix npm publish workflow

This is just a workflow release. No functional changes.

v0.9.0 Full auto repair

This release now contains full crash recovery and repairs corrupted files, brings lagging indexes up to sync and guarantees commits are only written in full.
The repair behavior is tested with a stress test writing to storage in a tight loop and artificially crashing the process. An upper bound on potential data loss is guaranteed and only depends on write buffer size, hence is configurable.

The documentation has received an overhaul and is available at https://node-event-storage.readthedocs.io/en/latest/

This release also drops official support for nodejs < 18, though it should still be functional.

This project is now considered production ready.

The next release will be a breaking change, moving the code base to ESM.
