v1.3.4

What's New

Bug Fix

• Root-only /llms.txt: Fixed issue #30 where /blog/post-slug/llms.txt incorrectly returned home page content instead of 404. The /llms.txt endpoint now only matches at the site root.

Generator Improvements (llmstxt.org compliance)

• Posts limit filter: Added tgp_llms_txt_posts_limit filter (default 50, use -1 for unlimited)
• Category exclusion: Added tgp_llms_txt_exclude_categories filter to exclude categories by slug
• Post dates: Each post listing now includes its publish date
• Last Updated timestamp: Header now includes Last Updated: YYYY-MM-DD
• Cleaner format: Simplified header to match llmstxt.org spec

Documentation

• Added new filter documentation to docs/HOOKS.md

v1.3.3

What's New

Code Quality (Issue #26)

• YAML Escaping: Fixed Frontmatter to properly escape YAML 1.2 special characters
• Markdown Title Escaping: Sanitize titles to escape special markdown characters
• N+1 Query Fix: Batch loading post meta with update_postmeta_cache()
• Cache Invalidation: Transient caching with automatic invalidation on post updates
• RateLimiter Extraction: Extracted rate limiting into dedicated class (SRP)
• Redis/Memcached Support: Rate limiter uses WordPress object cache

CI/CD Improvements

• Blacksmith Runners: Migrated all workflows to faster Blacksmith runners
• PHPUnit Fix: Removed coverage config that caused CI warnings
• E2E Tests: Fixed wp-env setup for reliable endpoint testing

Testing

• 140 PHPUnit tests (up from 78)
• Comprehensive MarkdownConverter test coverage
• E2E tests for /llms.txt and /*.md endpoints

Documentation

• Added docs/HOOKS.md with all filters and actions
• Added composer audit to CI pipeline
• Track composer.lock for reproducible builds

Housekeeping

• Removed .claude folder (consolidated in private repo)
• Added .claude/ to .distignore

v1.3.2

Bug Fix

Critical fix: Generator class had private constructor preventing /llms.txt endpoint from working.

Fixed

• Made Generator constructor public so EndpointHandler can instantiate it for serving /llms.txt requests
• The PSR-4 migration (v1.3.0) incorrectly made the constructor private

This fixes the "critical error" on /llms.txt endpoints while .md endpoints continued to work.

v1.3.1

Bug Fix

Critical fix: Include Composer autoloader in release package.

Fixed

• Release workflow now runs composer install --no-dev before packaging
• Removed vendor/ from .distignore so autoloader is included in release ZIP

This fixes the "Failed to open required vendor/autoload.php" error when installing the plugin.

v1.3.0

What's New

Features

• PSR-4 Autoloading: Migrated to PSR-4 namespaces (TGP\LLMsTxt\*) for better code organization
• Static Initialization Pattern: All classes now use Class::init() with private constructors
• Error Logging Infrastructure: New Logger class with error/warning/debug levels and action hooks for external integrations (tgp_llms_txt_error, tgp_llms_txt_warning)
• Rate Limiting: Added IP-based rate limiting (100 requests/minute) for public endpoints with standard headers

Security

• CSS color and gradient validation for block rendering
• Manifest structure validation for plugin updates
• Input sanitization for all proxy headers

Developer Experience

• Comprehensive PHPUnit test coverage (78 tests, 177 assertions)
• E2E testing with Playwright
• WordPress Coding Standards compliance

Breaking Changes

• Class names changed from TGP_Class_Name to TGP\LLMsTxt\ClassName
• Requires PHP 8.2+
