The latest Claude Code release is 2.1.97, not 2.3.0 (which is this
guide's own version). Update all 20 "Claude Code Version" footer lines
to accurately reflect the documented Claude Code version.

Update all documentation footers from generic "April 2026 / 2.1+" to
the specific sync date (April 9, 2026) and documented version (2.3.0).
Also add version/date footers to zh/CATALOG.md and
zh/01-slash-commands/README.md which were missing them.

* docs: sync all tutorials with latest Claude Code official docs (April 2026)
Update 44 documentation files to reflect the latest Claude Code features
from code.claude.com. Key content changes include new slash commands
(/ultraplan, /powerup, /sandbox), deprecated command removals (/pr-comments,
/vim), corrected skill description budget (1%/8K), new hook events
(PermissionDenied, InstructionsLoaded, ConfigChange), expanded Agent Teams
section, new plugin components (LSP, bin/, settings.json), and new CLI
flags (--bare, --tmux, --effort, --channels). Added "Last Updated: April
2026" metadata footer to all documentation files.
* fix(docs): correct env var values and alphabetical ordering
- CLAUDE_CODE_NEW_INIT=true → =1 in 02-memory and 09-advanced-features
- CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=true → =1 in 09-advanced-features
- Fix /powerup vs /plugin alphabetical order in slash commands table
* fix(docs): correct env var values in locale files (vi, zh)
Propagate CLAUDE_CODE_NEW_INIT=true → =1 and
CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=true → =1 corrections
to Vietnamese and Chinese translations.
* refactor(ci): shift quality checks to pre-commit, CI as 2nd pass
- Remove ci.yml (lint, security, pytest were only for EPUB scripts)
- Move EPUB build to pre-commit local hook (runs on .md changes)
- Add check_cross_references.py, check_mermaid.py, check_links.py scripts
- Add markdown-lint, cross-references, mermaid-syntax, link-check as
pre-commit hooks — mirrors all 4 CI doc-check jobs locally
- Remove spell check job from docs-check.yml (breaks on translations)
- Refactor docs-check.yml to reuse scripts/ instead of inline Python
- Add .markdownlint.json config shared by pre-commit and CI
- Update CONTRIBUTING.md with required dependencies and hook table
* fix(ci): resolve all CI check failures in docs-check workflow
- fix(check_cross_references): skip code blocks and inline code spans
to avoid false positives from documentation examples; fix emoji
heading anchor generation (rstrip not strip); add blog-posts,
openspec, prompts, .agents to IGNORE_DIRS; ignore README.backup.md
- fix(check_links): strip trailing Markdown punctuation from captured
URLs; add wikipedia, api.github.com to SKIP_DOMAINS; add placeholder
URL patterns to SKIP_URL_PATTERNS; add .agents/.claude to IGNORE_DIRS
- fix(check_mermaid): add --no-sandbox puppeteer config support via
MERMAID_PUPPETEER_NO_SANDBOX env var for GitHub Actions Linux runners
- fix(docs-check.yml): pass MERMAID_PUPPETEER_NO_SANDBOX=true to mermaid job
- fix(content): repair broken anchors in README.md, 09-advanced-features;
fix #plugins -> #claude-code-plugins in claude_concepts_guide.md;
remove non-existent ./docs/performance.md placeholder links; fix
dependabot alerts URL in SECURITY_REPORTING.md; update auto-mode URL
in resources.md; use placeholder pattern for 07-plugins example URL
- remove README.backup.md (stale file)
* fix(check-scripts): fix strip_code_blocks regex and URL fragment handling
- fix regex in strip_code_blocks to avoid conflicting MULTILINE+DOTALL
flags that could fail to strip indented code fences; use DOTALL only
- strip URL fragments (#section) before dispatching link checks to avoid
false-positive 404s on valid URLs with anchor fragments
* fix(check-scripts): fix anchor stripping, cross-ref enforcement, and mermaid temp file cleanup
- heading_to_anchor: use .strip("-") instead of .rstrip("-") to also strip leading hyphens
produced by emoji-prefixed headings, preventing false-positive anchor errors
- check_cross_references: always exit with main()'s return code — filesystem checks
should block pre-commit unconditionally, not silently pass on errors
- check_mermaid: wrap file-processing loop in try/finally so the puppeteer config
temp file is cleaned up even if an unexpected exception (e.g. UnicodeDecodeError) occurs
- docs-check.yml: remove now-unused CROSS_REF_STRICT env var
* fix(scripts): fix anchor stripping and mermaid output path
- Replace .strip('-') with .rstrip('-') in heading_to_anchor() so leading
hyphens from emoji-prefixed headings are preserved, matching GitHub's
anchor generation behaviour.
- Use Path.with_suffix('.svg') in check_mermaid.py instead of
str.replace('.mmd', '.svg') to avoid replacing all occurrences of .mmd
in the full temp path.
Update 23 files across all 10 tutorial directories and 7 reference
documents to match the latest Claude Code v2.1+ features and correct

for new features: Auto Memory, Remote Control, Web Sessions, Desktop
App, Agent Teams, MCP OAuth, Task List, Sandboxing, and more.
