  • Engineering Maintenance
    • We kicked off 2025 with a focus on technical priorities that are often challenging to address amidst endless product initiatives and WMF Annual Plan commitments. It's important to balance new feature development with engineering maintenance because a stable, well-maintained code ensures that new innovations are reliable, scalable, and sustainable over time. Without regular maintenance, technical debt can accumulate, leading to system inefficiencies, increased costs, and potential disruptions to user experience. Here are the highlights of what we worked on:
      • Remove Marketing experiment related code from GrowthExperiments T382499
      • Create a generic Campaign parameter for the Donor Thank You page T380405
      • Switch GETempLinkRecommendationSwitchTagClearHook to true at all wikis T379522
      • Running extensions/Babel/maintenance/migrateConfigToCommunity.php with BabelUseCommunityConfiguration=false results in a fatal error T383904
      • PHP Warning: Stats: Cannot add labels to a metric containing samples for 'update_mentee_data_seconds' T383477
      • Migrate GrowthExperiments.Mentorship Module to statslib T374048
      • Ensure ORES topics are not loaded through legacy CommunityConfiguration code T367576
      • GrowthExperiments cypress setup assumes fixed LocalSettings path T383310
      • Migrate ComputedUserImpactLookupTest test to CommunityConfiguration 2.0 T380580
      • Deploy the CommunityConfiguration extension to all Beta Cluster wikis T383911
      • Switch GETempLinkRecommendationSwitchTagClearHook to true at all wikis T379522

      • Delete mw:MediaWiki:NewcomerTopicsOres.json T383418
      • Deprecate calling legacy Community Configuration T383330
      • Replace deprecated mediawiki.Uri usage in GrowthExperiments' SuggestedEditSession T380770
  • "Add a Link" Release at English Wikipedia
    • We moved from a 3% to a 5% release of "Add a Link" at English Wikipedia T382382
    • We will discuss increasing the rollout to a larger group, and consider further task improvements based on Community feedback.
