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.
The autoCheckpoint setting does not exist in Claude Code's settings
schema. Checkpointing is automatic and built-in — every user prompt
creates a checkpoint. Replace the incorrect config example with the
actual cleanupPeriodDays setting, which controls retention period.
Fixes#18
Update 23 files across all 10 tutorial directories and 7 reference
documents to match the latest Claude Code v2.1+ features and correct
outdated content including model names (4.5→4.6), permission modes,
hook events, CLI syntax, MCP config paths, plugin manifest format,
checkpoint commands, session management, and URLs. Add documentation
for new features: Auto Memory, Remote Control, Web Sessions, Desktop
App, Agent Teams, MCP OAuth, Task List, Sandboxing, and more.

- Add logo to all subdirectory README files in feature folders (01-10) and plugins
- Replace old markdown image syntax with HTML picture element for dark/light mode adaptation
