What does this PR do?

V2 release notes now start with a short ### Highlights section, followed by the detailed Core / TUI / Desktop / SDK / Extensions sections as before. The format comes from the iOS app's What's New: a few-word Title Case title, then one or two plain second-person sentences about what you can now do, naming the exact command or place in the UI.

Changes, all in script/release.ts, which builds the V2 review in reviewPrompt. script/changelog.ts and the changelog command are not on the V2 release path; raw-changelog.ts still filters on V1 package paths.

• Highlights: 2–5 user-visible, shareable changes, ordered by how much users care. The section is left out when nothing qualifies. Internal work, broad polish and unreleased features are skipped. Each highlight must be checked against its PR and diff, link the PR, and also appear in the detailed sections.
• Headings: the notes use ### for sections and #### for Improvements / Bug fixes, never # or ##. This fits the ## vX.Y.Z — date entries in CHANGELOG.md and splitting on ^## v\d.
• Thanks: team members listed in .github/TEAM_MEMBERS are no longer thanked, which fixes existing output. Highlights carry no thanks.
• New --print [--from <tag>] [--to <ref>]: generates and prints the review for any range without opening the editor or triggering a release. --from / --to are rejected without --print, so a real release still always compares the latest stable tag to HEAD.

The marker extraction, release_notes input, CHANGELOG.md writing and Discord announcement are unchanged. Because the highlights come first, they survive the Discord action's 4096-character embed limit.

Sample: v2.0.24..v2.0.25 highlights

Highlights

• Preview Microsoft Office Files: Open .docx, .xlsx, and .pptx files directly in the file viewer. Previews run locally and support document text, spreadsheet navigation, and presentation notes. (#53305)
• Remote Pairing through OpenTunnel: Run opencode pair --remote to expose the background service through OpenTunnel and receive a single-use remote pairing link. (#53837)
• Connect with AWS and Azure Profiles: In /connect, choose an AWS profile for Amazon Bedrock or Microsoft Entra ID (Azure CLI) for Azure instead of storing credentials in OpenCode. (#53626, #53794)
• Reopen Closed Tabs: Right-click the new-session control in horizontal or vertical tabs to restore a recently closed session. (#51973)

Sample: v2.0.23..v2.0.24 highlights

Highlights

• Native Vercel AI Gateway Support: Connect the Vercel AI Gateway provider to use Gateway-hosted models with automatic routing to Messages, Responses, or Chat Completions. Reasoning controls, prompt caching, provider routing, and BYOK options are supported. (#52643, #53432)
• Find Sessions Awaiting Input: Press Ctrl+O or run /sessions in the TUI to find sessions waiting for a question or permission at the top, marked with ? or !. This also covers sessions blocked by child subagents. (#53435)
• Persistent /btw Answers: Each /btw question now opens in its own side-panel tab and remains available across reloads until you close it. Concurrent questions run independently, and interrupted answers offer Retry. (#53270)
• Recover Sessions with Missing Folders: When a session’s folder no longer exists, use Choose worktree or Choose directory in the composer to move the session without losing its timeline. (#53268)

• Delayed guarded plugin activation until policy evaluation is ready. (#53819)

How did you verify your code works?

• Ran ./script/release.ts --print against v2.0.24..v2.0.25, v2.0.23..v2.0.24 and v2.0.25..origin/v2, and refined the prompt over three passes. The first pass had a vague "mobile workflow" highlight and two wrong UI details (opencode pair without --remote, and a "title bar" menu), and it thanked team members. All of these are fixed in the samples above.
• Checked each sample highlight against its PR body or diff (feat(app): preview Word, Excel and PowerPoint files #53305, feat(cli): pair remotely through OpenTunnel #53837, feat(core): add AWS profile setup for Bedrock #53626, feat(core): connect Azure through the Azure CLI as an external credential #53794, feat(app): show recently closed tabs menu #51973, feat(tui): surface sessions awaiting input at the top of the open menu #53435, feat(app): restore the session location missing prompt #53268, fix(cli): serve remote access on a random unguessable subdomain #53962, perf(core): speed up and harden snapshot capture #51996).
• bun run check passes. --help works, and --from without --print is rejected.
• No release was triggered.

Follow-ups: Discord doesn't render ####. The action's reduce_headings option or a highlights-only Discord body would help.
