  • [Nina]
    • Release updates 1.72.x: Theia IDE 1.72.300 promoted to stable
    • New vulnerability report, scheduled to fix with 1.73.x (perhaps also follow ups)
  • [Stefan] React 19 compatibility and React 19 switch (#17567)

  • [Nina]:
    • Release updates 1.72.x: Theia IDE 1.72.x Preview Testing ongoing
      • 1.72.2 patch includes fix for file watcher issue, 1.72.3 planned, promote to stable expected end of the week

2026-06-02

  • [Jonas]: Great news: Nina is a new project lead, congratulations!
  • [Nina]:
    • Release updates 1.72.x: Theia IDE 1.72.x Preview Testing ongoing
    • Some reports, one severe about file watcher issues (https://github.com/eclipse-theia/theia/discussions/17595)
    • Ad merge queues from last week about bypassing the queue:
      • bypass actors: small trusted group can skip the queue. Risk: weakens queue guarantees
      • Temporary relax rule in EclipseFdn Otterdog config: needs Eclipse Foundation team member merge. Risk: too slow for urgent cases / may stay relaxed.
      • ==> decided to introduce the merge queues without bypassing option. We can re evaluate in 1-2 months if it causes any friction and revert if needed.

2026-05-26

  • [Nina]
    • Eclipse Theia v1.72.0 release scheduled for Thursday, 2026-05-28
    • Proposal: Merge queues
      • GitHub merge queues re-run CI on each approved PR against the latest master (plus any earlier queued PRs) before merging, instead of trusting the PR's stale base. Today we only check merge conflicts, not build compatibility against current master
      • Catches semantic conflicts where two PRs are green in isolation but break when combined, keeping master continuously green for everyone branching off it
      • Concrete recent example: #17521 (adding tests for the code completion agent) and #17447 (white-labeling of the product name in AI features) each passed CI on their own branches, but together broke the code completion agent test on master and required a follow-up (#17527)
      • Queue check is intentionally lightweight (lint, build, test on single Ubuntu/Node ~15-20 min). Full matrix already passed on the PR and isn't repeated, so per-PR cost is not too high
      • Requires an repo config change (via Otterdog, allows_merge_queue: true + status checks on master)
      • I already drafted workflow + Otterdog changes a while back, but at the time it didn't seem too urgent enough to continue

  • [Stefan]
    • Logging proposal #15359 update: Name all loggers according to this scheme: [optional-purpose]package-name:class-name#optional-suffix, e.g. remote:BackendRemoteServiceImpl
    • Combined with a regex or wildcard (*) based logger configuration #17466
    • Enforced via ESLint rule #17468

  • [Nina]
  • [Mark] Looked at bundling improvements:
    • Vite doesn't fit our usecase well and required too many workarounds
    • I've updated the ESBuild PR. It should be ready for testing - I'll try to fix the CI failures

  • Growing number of Pull Requests to review [Stefan]
    • Main issues:
      • Reviewing takes considerable time
      • Reviewing is much less "publicly" awarded compared to original authorship
      • LLMs accelerate the mismatch between development time / review time.
      • Reviewing some of the pull requests feels like LLM development
    • Suggestions:
      • Split reviewing into multiple aspects (high-level/architecture, code review, testing)
      • Make reviewing more prominent, for example via git trailers, like in the Linux kernel, e.g. Tested-by, Reviewed-by, Acked-by, Co-developed-by, Co-authored-by (Github/Gitlab special UI).
      • Allow "AI reviews" to catch/improve low-mid quality contributions before non-trivial "review time" is spent
      • Other ideas?
