Apache Airflow
Airflow 3.4 moves to a second release candidate three days after the first.
A side-by-side editorial comparison of Retool and Sonarr — release velocity, themes, recent moves, and the top alternatives to consider.
Retool's app builder hits GA, generating React apps, with spend controls beside it.
Retool's app builder is generally available: it builds React apps from natural language, from MCP-compatible coding agents or from imported React code. On the same day Retool shipped limits on AI credit and token usage by user, group and model, along with credit packs by card on all paid plans. Private npm registries for Enterprise apps and GPT 6.1 Terra followed, while self-hosted stable channels took three more 4.34 updates.
Sonarr 5.0 swaps its interactive search table for cards and trims what counts as advanced.
Sonarr keeps publishing 5.0 test builds every few days. Build 2907 replaces the interactive search table with cards, marks advanced settings and moves fewer settings behind that label, and cuts duplicate requests on load. Build 2870 added TMDb import lists and a Multi-Season Pack release type. Accessibility work continues, with more context on System page and Manual Import buttons.

Retool is turning AI app generation into a metered product line: the builder is the surface, and credits and spend limits are how it gets sold and governed. Private npm registries point the same way, since generated React apps need a company's own packages. Self-hosted customers stay on a separate steady cadence of Edge builds and stable patches.
Expect more Enterprise controls around app builder output and the next frontier model added soon after launch. The entries don't show how AI credits are priced.

5.0 is still mixing contributor features with interface rework and accessibility polish. Performance work now joins it, with cache updates, import list sync and load-time requests all optimized in one build. Basic Auth removal and file safety defaults set its stricter baseline.
Expect more interface and accessibility fixes before 5.0 reaches the stable channel. Larger changes are still landing in test builds, so the timing of that release remains unclear.
