-# Guide to automated release notes maintenance
-
-This guide is for maintainers and reviewers who manage the automated release
-notes generated by Gemini CLI. It covers the architecture of the automation and
-provides troubleshooting steps for common issues.
-
-## Architecture and governance
-
-The automated release notes process is divided between a GitHub Action and a
-Gemini CLI skill.
-
-### GitHub Action
-
-The GitHub Action (`.github/workflows/release-notes.yml`) governs the triggering
-mechanism and infrastructure. It runs automatically when a release is published
-or when manually dispatched. The action is responsible for:
-
-- Extracting the release **version**, **date**, and **raw notes** from the
-  GitHub release.
-- Passing the extracted information to Gemini CLI.
-- Updating changelog pages.
-- Creating a pull request with the generated changelog files.
-
-### docs-changelog skill
-
-The `docs-changelog` skill governs the actual content generation. It takes the
-provided version, date, and raw data, processes it, and updates the markdown
-files. It formats the content according to project standards and determines
-whether to append to an existing page or create a new one based on the semantic
-version.
-
-Specifically, the skill updates the following pages based on the release
-version:
-
-- **New Minor Stable Versions (e.g., `v1.2.0`):**
-  - Fully replaces `docs/changelogs/latest.md` with a new highlights section and
-    the full changelog.
-  - Prepends a brief announcement summary to `docs/changelogs/index.md`.
-- **New Minor Preview Versions (e.g., `v1.3.0-preview.0`):**
-  - Fully replaces `docs/changelogs/preview.md` with a new highlights section
-    and the full changelog.
-- **Patch Stable Versions (e.g., `v1.2.1`):**
-  - Edits `docs/changelogs/latest.md` by updating the version header, date, and
-    "Full Changelog" link, and prepending new "What's Changed" items without
-    replacing the entire file.
-- **Patch Preview Versions (e.g., `v1.3.0-preview.1`):**
-  - Edits `docs/changelogs/preview.md` similarly to stable patches, updating the
-    header, date, and link, and appending new items without rewriting the file.
-- **Nightly Releases:**
-  - The skill skips nightly versions entirely and makes no updates.
-
-## Troubleshooting
-
-This section covers common issues you might encounter with the automated release
-notes and how to resolve them.
-
-### Skipped minor versions do not create a new entry
-
-Sometimes new releases skip straight to a minor or patch version, such as
-`x.x.1`. In these cases, a new entry is not created.
-
-The skill expects to update the date and append a line for any new changes to an
-existing `x.x.0` page, instead of fully refreshing the page. If the `x.x.0` page
-does not exist, the skill cannot append the notes.
-
-To fix this issue:
-
-1. Navigate to the **Actions** tab and select the **Generate Release Notes**
-   workflow.
-2. Manually run the action.
-3. Copy and paste the version information, but use the `x.x.0` nomenclature (for
-   example, `1.2.0` instead of `1.2.1`) to force the skill to generate a fresh
-   page.
-4. Once the pull request is created, manually edit the version number in the
-   generated markdown file to match the correct `x.x.1` version before merging.
-
-### Pull request contains too many changed files
-
-Occasionally, the generation process results in a pull request that has too many
-changed files. The exact cause of this behavior is unknown.
-
-To fix this issue:
-
-1. Go to the Actions run that generated the pull request (this fix also applies
-   to failed runs).
-2. Rerun the action. A fresh run typically resolves the issue and correctly
-   scopes the file changes to only the changelog.

 ## Highlights
 
-- **Context Manager Simplification:** Completed a significant refactoring of the
-  context management system to improve reliability and architectural clarity.
-- **A2A Usage Metadata:** Enhanced the Agent-to-Agent protocol to expose usage
-  metadata, enabling more transparent resource monitoring.
-- **Terminal & PTY Robustness:** Resolved several critical issues related to
-  terminal interactions, including Termux relaunch loops and PTY resize errors.
-- **Routing Optimizations:** Updated default auto-routing and bypassed
-  classifiers for specific tool responses to prevent orphaned function errors.
-- **Tool Execution Control:** Forced the `update_topic` tool to execute
-  sequentially, ensuring consistent narrative flow in agent interactions.
+- **Caretaker Services:** Introduced a new caretaker triage worker including
+  core foundational modules, main worker execution loops, egress action
+  publishers, and octokit GitHub Action handlers.
+- **Robust File Editing:** Core tools like `write_file` and `replace` now bypass
+  LLM corrections for JSON and IPYNB files to ensure accurate and direct file
+  modifications.
+- **Plan Mode Improvements:** Simplified plan mode write policies to natively
+  support writing to relative paths, enhancing project directory navigation.
+- **Enhanced Account Visibility:** Improved clear user-facing messages when the
+  user account does not have a Code Assist tier, and enriched shared project
+  quota limit errors with setup instructions.

 ## Highlights
 
-- **Model Update:** Added support for transitioning to the Flash GA model when
-  the experimental flag is enabled, providing access to the latest model
-  improvements.
-- **Improved Stability:** Hardened PTY resize logic to prevent native crashes,
-  ensuring a more robust terminal experience.
-- **Bug Fix:** Resolved an issue where an invalid `preferredEditor`
-  configuration could lead to a notification spam loop.
-- **CI Enhancements:** Optimized Pull Request labeling and introduced batch
-  workflows to improve development efficiency.
+- **Caretaker LLM Triage Orchestrator**: Implemented the LLM triage orchestrator
+  and container build configuration to support caretaker triage workflows.
+- **Enhanced Workspace Trust & Sandbox Hardening**: Aligned macOS permissive
+  Seatbelt profiles with the deny-default model and enforced workspace trust and
+  task isolation in the Agent-to-Agent (A2A) server to prevent remote code
+  execution (RCE).
+- **Core Robustness & API Protections**: Mitigated infinite ReAct and prompt
+  injection loops, and prevented 400 Bad Request errors by grouping cancelled
+  tool responses and coalescing consecutive roles.
+- **Robust Credentials & Fallbacks**: Restored the
+  `GOOGLE_APPLICATION_CREDENTIALS` environment variable fallback and
+  sequentially verified cached credentials.
+- **Evaluation Coverage Reporting**: Added a new command to generate
+  comprehensive eval coverage reports.
