What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **changed** — Notice configuration now comes from a static, cacheable repository file with a bundled disabled fallback and deterministic rollout assignment, instead of calling PostHog's feature-flag evaluation API
- **changed** — RedisDBConfig now uses Pydantic's native extra="forbid" handling for unknown fields instead of a custom model validator

**Improvements:**
- **OSS notices:** Notice configuration now comes from a static, cacheable repository file with a bundled disabled fallback and deterministic rollout assignment, instead of calling PostHog's feature-flag evaluation API. This keeps notices fail-safe when the remote config is unavailable and removes the PostHog feature-flag request from notice evaluation ([#7185](https://github.com/mem0ai/mem0/pull/7185))
- **Vector Stores:** `RedisDBConfig` now uses Pydantic's native `extra="forbid"` handling for unknown fields instead of a custom model validator, preserving strict validation while returning standard Pydantic errors ([#7089](https://github.com/mem0ai/mem0/pull/7089))
