Analyze these commits and generate a changelog of all notable user facing changes, grouped by area.

Each commit below includes:
- [author: username] showing the GitHub username of the commit author
- [areas: ...] showing which areas of the codebase were modified

Commits between ${previous} and HEAD:
${commits}

Group the changes into these categories based on the [areas: ...] tags (omit any category with no changes):
- **TUI**: Changes to "opencode" area (the terminal/CLI interface)
- **Desktop**: Changes to "desktop" or "tauri" areas (the desktop application)
- **SDK**: Changes to "sdk" or "plugin" areas (the SDK and plugin system)
- **Extensions**: Changes to "extensions/zed", "extensions/vscode", or "github" areas (editor extensions and GitHub Action)
- **Other**: Any user-facing changes that don't fit the above categories

Excluded areas (omit these entirely unless they contain user-facing changes like refactors that may affect behavior):
- "nix", "infra", "script" - CI/build infrastructure
- "ui", "docs", "web", "console", "enterprise", "function", "util", "identity", "slack" - internal packages

Rules:
- Use the [areas: ...] tags to determine the correct category. If a commit touches multiple areas, put it in the most relevant user-facing category.
- ONLY include commits that have user-facing impact. Omit purely internal changes (CI, build scripts, internal tooling).
- However, DO include refactors that touch user-facing code - refactors can introduce bugs or change behavior.
- Do NOT make general statements about "improvements", be very specific about what was changed.
- For commits that are already well-written and descriptive, avoid rewording them. Simply capitalize the first letter, fix any misspellings, and ensure proper English grammar.
- DO NOT read any other commits than the ones listed above (THIS IS IMPORTANT TO AVOID DUPLICATING THINGS IN OUR CHANGELOG).
- If a commit was made and then reverted do not include it in the changelog. If the commits only include a revert but not the original commit, then include the revert in the changelog.
- Omit categories that have no changes.
- For community contributors: if the [author: username] is NOT in the team list, add (@username) at the end of the changelog entry. This is REQUIRED for all non-team contributors.
- The team members are: ${team.join(", ")}. Do NOT add @ mentions for team members.

IMPORTANT: ONLY return the grouped changelog, do not include any other information. Do not include a preamble like "Based on my analysis..." or "Here is the changelog..."

<example>
## TUI
- Added experimental support for the Ty language server (@OpeOginni)
- Added /fork slash command for keyboard-friendly session forking (@ariane-emory)
- Increased retry attempts for failed requests
- Fixed model validation before executing slash commands (@devxoul)

## Desktop
- Added shell mode support
- Fixed prompt history navigation and optimistic prompt duplication
- Disabled pinch-to-zoom on Linux (@Brendonovich)

## Extensions
- Added OIDC_BASE_URL support for custom GitHub App installations (@elithrar)
