Change

The TUI changelogs (packages/tui/CHANGELOG.md and CHANGELOG.zh-CN.md) stopped at 0.5.5 and never covered 0.5.0–0.5.4, so /changelog and the per-version release notes shown in the TUI were empty for every public release from 0.5.0 to the current 0.6.5. This PR adds the missing entries in English and Simplified Chinese:

• New sections: 0.5.0, 0.5.1, 0.5.2, 0.5.3, 0.5.4, 0.5.6, 0.5.8, 0.5.9, 0.5.10, 0.6.0, 0.6.1, 0.6.2, 0.6.3, 0.6.4 and 0.6.5, one per public v* tag/GitHub Release. There is no 0.5.7 tag, so its changes are listed under 0.5.8.
• Each section is based on the commits between consecutive public tags (git log vA..vB), not on another build's version numbering. Examples: lightweight mode, image limits and request timeouts are under 0.6.3 because they shipped in v0.6.3. Features that are not in this repository are left out.
• 0.5.5 adds the terminal title/notification, update-proxy, memory-output and long-session changes it shipped (feat(tui): improve session titles and terminal notifications #355, feat: sync reviewed 0.5.5 runtime improvements #367, perf: reduce repeated work in long sessions #314), drops a stray blank line, and its date changes from 2026-09-25 to 2026-09-27, the GitHub Release date.
• Dates use the GitHub Release date (UTC+8). Older sections (0.4.12 and earlier) are unchanged.
• Left out on purpose: CI/test/docs-only commits, the Pocket Pet example, and fix(tui): preserve native scrollback during automatic updates #389/fix(tui): stabilize native history and diff overlay frames #390, which shipped in 0.5.9 and were reverted in 0.5.10 (Revert #390 and #389 to restore TUI scrollback baseline #396).

Labels: documentation, tui, cli.

Validation

• Parsed both files with the TUI's own changelog parser (extractTuiVersionChangelogEntries / extractTuiChangelogMarkdown in packages/tui/src/tui/features/changelog/content.ts) using a temporary Vitest file kept outside the repository. Every version from 0.4.12 to 0.6.5 returns bullet entries in both languages, and the rendered changelog starts at 0.6.5.
• git diff shows that existing entries outside 0.5.5 are byte-for-byte unchanged. The new English text is wrapped at 100 columns with Prettier.
• pnpm verify (full profile, macOS arm64, Node 26.4.0) on the committed head 2717dcb: check:source, check:tsconfig, source export, test:release-tools, lint:tui, typecheck, build, check:standalone and test:artifact passed. test:capabilities had 5547 tests pass and 1 fail: update-runtime.test.ts > heals receipts pinned to a Homebrew Cellar keg via the stable opt path. The failure comes from the host, not this change. The local Homebrew node is dynamically linked to @rpath/libnode.147.dylib, and the copy of the binary that the test places in its fake Cellar cannot load the library (dyld: Library not loaded). Because verify stops at the first failure, I ran the remaining gates separately: test:status-contract, test:smoke, test:byok, test:policy and test:sandbox all passed.
• Performance: basic (changelog content only).
• NOT RUN: Windows gates (pnpm verify --list shows them as not applicable on this macOS host). I did not open /changelog interactively in a running TUI.

Publication and contribution checks

• No credentials, account data, real user content, internal source history or private review material is included.
• Added/removed source files were reviewed before regenerating release/public-source.json; new tests are declared in test/vitest-suites.json where applicable. (No files were added or removed.)
• Shared English/Chinese documentation and capability/verification records are updated where applicable. Mock/offline results are not described as live-service acceptance.

Maintainer handoff
