Harbor
Harbor's patch train is now mostly about undoing regressions from its own security hardening.
A side-by-side editorial comparison of Apache Airflow and MISP — release velocity, themes, recent moves, and the top alternatives to consider.
Airflow's feed right now is a wall of provider release candidates, not core changes.
Every entry visible is a provider-package release candidate from the same October 6 batch: Telegram, Trino, Teradata, Vespa, Yandex, Tableau, Weaviate, Vertica, YDB and Zendesk, all at patch-level rc1. None carries notes beyond the batch date. The signal here is the size of the integration surface Airflow maintains, not any single change.
MISP 2.5.50 deletes legacy discussions, templates and allowedlists as security fixes keep coming.
MISP is deep in a security-remediation cycle: 2.5.46, 2.5.47, 2.5.48 and now 2.5.50 each ship externally reported fixes, and 2.4.221 backported 57 of them to the EOL branch. 2.5.47 added PostgreSQL support and a first AI-assisted analysis integration. 2.5.50 moves Redis host settings to CLI-only and closes event-index and object-search information leaks. It also starts deleting legacy features outright.

Airflow ships its connectors on a batched, independently versioned cadence, so provider churn will keep dominating this feed between core releases. The breadth runs from legacy warehouses (Teradata, Vertica) to vector stores (Weaviate, Vespa), which keeps the scheduler relevant as pipelines feed retrieval systems.
Expect these rc1 tags to promote to final provider releases with no content change; the entries shown give no read on the next core Airflow release.

It also starts deleting legacy features outright.
The project is shifting from adding hardening patches to shrinking its attack surface. In 2.5.50, event discussions become analyst notes, legacy templates become event templates, and signature allowedlists become warninglists, with migrations and logged failures. Combined with the Overmind UI migration and the database abstraction, this looks like a deliberate cleanup of the 2.5 codebase.
Expect further legacy features to be migrated and removed in the next releases, alongside more advisories from the ongoing review. Admins with workflows on the removed discussion trigger will need to adapt.
