Official release notes (help.openai.com)

Notes newly present in this hop (historical ground truth; not proof they launched in-window):

  • 2025-02-14 — Safari default-search setup; logout confirmation (iOS/web); Android conversation-parsing and composer/launch animation updates; iOS perf fixes; Whisper dictation shows a text preview after recording.
  • 2025-02-06 — Canvas sharing: share a Canvas asset (React/HTML, document, or code) from the Canvas toolbar, like sharing a chat.
  • 2025-01-17 — Custom instructions UI refresh (traits, tone, rules); rolling out on chatgpt.com and Windows; mobile/macOS later; EU/EFTA soon.
  • 2025-01-15 — Import from Chat into Canvas (full response or code block); web only.
  • 2025-01-14 — Scheduled tasks beta (Plus/Pro/Teams).
  • 2024-12-13 — Projects (file/chat grouping, project instructions; Plus/Team/Pro).
  • Older note backlog also landed (GPT-4o mini, GPT-4o, data-analysis upgrades, voice for all, GPTs, browsing GA, etc.).
  • 2025-02-21 note edit is non-product (embedded challenge-script noise stripped).

Flags

Retry / cancellation

  • Added honor_grace_deadline_for_retry_cancellation

Instruction / prompt catalog

  • Removed a block of instruction-module flags: appConnectionInstructions, artifactInstructions, baseInstructions, browserInstructions, dailyBriefingInstructions, emailMessagingInstructions, onboardingInstructions, skillInstructions, websiteInstructions, writingStyleInstructions, writingStyleSetupInstructions
  • Removed tax_types

Statsig

  • −2 hashed dynamic configs; gates/layers unchanged

Thin surface hop overall: release-note corpus catch-up plus instruction-flag cleanup; no high-signal composer/nav/Voice/Projects flag launches in the readable set.
