Mozillamozilla/fxa
  • Replaced a hardcoded 28-day session expiry with the auth server's configured token lifetime, closing an open FIXME and adding unit tests.#20801
  • Fixed a misspelled OAuth integration test description, split out as its own PR at the maintainer's request.#20800
  • Gave the disabled-StatsD stub a histogram method, so Redis metrics calls no longer throw at runtime when metrics are off.#20799
  • Stopped settings buttons from shrinking, so Japanese, Chinese and Korean labels no longer stack one character per line.#20724
  • Corrected a typo in the GraphQL error returned for an invalid metrics opt state, in both the resolver and its tests.#19930
  • Restored the localized string for an unset secondary email, fixing an l10n regression that showed a hardcoded 'None'.#19929
Cal.comcalcom/cal.diy
  • Made the push test notification use the instance URL instead of app.cal.com, so it works on self-hosted installs, and returned 400 on invalid payloads.#29673
Apache Airflowapache/airflow
  • Logged an empty plugins folder at debug level and warned only on real import failures, so new installs no longer look broken.#72432
  • Updated the contributor and Breeze docs for Colima, using docker context and DOCKER_HOST instead of a socket symlink that conflicts with Docker Desktop.#72431
Bravebrave/brave-search-mcp-server
  • Removed a nonexistent offset parameter from the image search schema, which kept leading agents to make wasted calls.#348
Oppiaoppia/oppia
  • Removed @ts-nocheck from seven Group 12 domain spec files and fixed the strict TypeScript errors so they still typecheck and pass.#27839
