Apache Airflow
Airflow 3.4 moves to a second release candidate three days after the first.
A side-by-side editorial comparison of Apache DolphinScheduler and Retool — release velocity, themes, recent moves, and the top alternatives to consider.
Apache DolphinScheduler adds missed fire policy and AWS EMR Serverless integration in its 3.4.x patch series.
DolphinScheduler 3.4.x is a mature data workflow scheduler on a quarterly patch cadence. Recent releases address real operational gaps: schedule missed fire policy handling (what happens when a job doesn't fire at its scheduled time), Amazon EMR Serverless as a new task plugin, configurable maximum runtime for workflow and task instances, and complement data dependency support. Security hygiene also landed — HTTP TRACE disabled, plaintext passwords removed from worker logs.
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.

Security hygiene also landed — HTTP TRACE disabled, plaintext passwords removed from worker logs.
The 3.4.x series is consolidating scheduler reliability (missed fire, dispatch timeout for missing worker groups, configurable max runtime) while expanding cloud integrations (AWS EMR Serverless, with prior support for SageMaker and Kubernetes from the 3.3.0 connection center work). The pattern is incremental operational hardening rather than architectural change. The 3.3.0-alpha connection center abstraction (Zeppelin, SageMaker, K8s) is the most notable structural addition in the visible history.
Additional AWS or cloud provider task plugins are the most likely near-term additions given the EMR Serverless landing. Scheduler reliability work will continue as the missed fire policy and timeout logic get extended to more edge cases.
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.
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.
