 ## [Unreleased]
 
+## [0.6.0] - 2026-02-02
+
+### Changed
+
+- **Replaced Twig with native PHP templates** - Major refactoring to remove external dependency
+  - Removed `twig/twig` from composer.json dependencies
+  - All 25 Twig templates converted to native PHP templates
+  - New `render()` method in Plugin.php uses PHP include with output buffering
+  - New `render_partial()` helper method for including partials from within templates
+  - Templates support theme overrides via `fedistream/` directory in themes
+  - Improved performance by eliminating Twig compilation overhead
+  - Reduced plugin size by removing Twig and its dependencies (symfony/polyfill-ctype, symfony/polyfill-mbstring)
+
+### Removed
+
+- Twig template engine dependency
+- All `.twig` template files (replaced with `.php` equivalents)
+- Twig-related initialization code in Plugin.php
+
+## [0.5.1] - 2026-02-02
+
+### Added
+
+- **Localhost license bypass** - License check is automatically bypassed on local development environments
+  - Detects `localhost`, `127.0.0.1`, `::1`
+  - Detects common local TLDs: `.local`, `.test`, `.localhost`, `.dev.local`
+  - Allows full plugin functionality without license on development sites
+
+## [0.5.0] - 2026-02-02
+
+### Added
+
+- **Prometheus Metrics Integration** - Expose FediStream metrics for monitoring
+  - Content metrics: `fedistream_content_total` (by type/status), `fedistream_genres_total`, `fedistream_moods_total`
+  - Engagement metrics: `fedistream_plays_total`, `fedistream_plays_today`, `fedistream_favorites_total`, `fedistream_local_follows_total`, `fedistream_listening_history_entries`
+  - User metrics: `fedistream_users_with_library`, `fedistream_users_following_artists`, `fedistream_notifications_total`, `fedistream_notifications_pending`
+  - WooCommerce metrics (conditional): `fedistream_purchases_total`, `fedistream_customers_total`, `fedistream_products_total`
+  - ActivityPub metrics (conditional): `fedistream_activitypub_followers_total`, `fedistream_activitypub_followers_by_artist`, `fedistream_activitypub_reactions_total`
+  - New setting in Integrations tab to enable/disable Prometheus metrics
+  - Requires WP Prometheus plugin to be active
+
+## [0.4.9] - 2026-02-02
+
+### Changed
+
+- **Reverted nuclear option** - Restored conditional the_content filter usage
+  - `get_post_data()` now uses the_content filter only when NOT in shortcode context, NOT at depth > 1, and NOT loading page template
+  - All other protections remain in place (render depth, page template loading flag, main template lock, shortcode context)
+  - Memory leak investigation to be continued later
+
+## [0.4.8] - 2026-02-02
+
+### Fixed
+
+- **Nuclear option: NEVER apply the_content filter** - Completely removed the_content filter usage (reverted in 0.4.9)
+  - `get_post_data()` now ALWAYS strips shortcodes and uses raw content
+  - NEVER calls `apply_filters('the_content', ...)` or `get_the_excerpt()`
+  - FediStream posts don't need shortcode processing in their content anyway
+  - This guarantees no recursion through WordPress hook system
+
+## [0.4.7] - 2026-02-02
+
+### Fixed
+
+- **Hard main template rendering lock** - Added additional protection at Plugin::render() level
+  - Added `$rendering_main_template` flag that completely blocks any other render calls while main template is rendering
+  - Reduced MAX_RENDER_DEPTH from 5 to 2 (allows one level of {% include %} but prevents deeper recursion)
+  - template-wrapper.php now passes `is_main_template = true` to enable the hard lock
+  - Any render attempt during main template rendering is immediately blocked
+
+## [0.4.6] - 2026-02-02
+
+### Fixed
+
+- **Page template loading lock** - Block ALL shortcode rendering during page template loading
+  - Added `$loading_page_template` flag in TemplateLoader
+  - template-wrapper.php now sets this flag before loading theme header/footer
+  - Shortcodes::render_template() checks this flag and returns early if set
+  - This prevents any recursion triggered by theme components, widgets, or other plugins during page template loading
+  - Main template rendering still works (uses Plugin::render() directly, not through Shortcodes)
+
+## [0.4.5] - 2026-02-02
+
+### Fixed
+
+- **Multi-layer recursion protection** - Added additional safeguards against infinite Twig rendering
+  - Added render depth tracking in `Plugin::render()` with max depth of 5
+  - Strip shortcodes from content when in shortcode context (prevents any later `do_shortcode()` calls from triggering recursion)
+  - This addresses the Twig StagingExtension.php recursion error
+
+## [0.4.4] - 2026-02-02
+
+### Fixed
+
+- **Fix excerpt-triggered recursion** - `get_the_excerpt()` internally calls `the_content` filter when generating auto-excerpts
+  - When in shortcode context, now uses raw `$post->post_excerpt` or generates simple excerpt with `wp_trim_words()` instead
+  - This was the remaining recursion path causing memory exhaustion in `class-wp-hook.php`
+
+## [0.4.3] - 2026-02-02
+
+### Fixed
+
+- **Further memory leak fix** - v0.4.2 fix was still incomplete
+  - Changed `$in_shortcode_context` boolean to `$shortcode_context_depth` counter to properly handle nested shortcodes
+  - Added shortcode context protection to `template-wrapper.php` for single page views
+  - This fixes the remaining recursion path where `the_content` filter was still being applied when viewing single FediStream posts (artists, albums, tracks, playlists)
+
+## [0.4.2] - 2026-02-02
+
+### Fixed
+
+- **Complete fix for memory leak** - v0.4.1 fix was incomplete
+  - Added `$in_shortcode_context` flag to TemplateLoader to track when we're rendering shortcodes
+  - All shortcode render methods now call `enter_shortcode_context()` before loading data
+  - When in shortcode context, `the_content` filter is always skipped to prevent recursive shortcode processing
+  - This prevents infinite recursion when post content contains FediStream shortcodes
+
+## [0.4.1] - 2026-02-02
+
+### Fixed
+
+- **Critical memory leak** causing "Allowed memory size exhausted" errors in Twig's StagingExtension
+  - Root cause: `apply_filters('the_content')` in `get_post_data()` triggered shortcode processing, causing infinite recursion when post content contained FediStream shortcodes
+  - Added recursion depth tracking with `MAX_RECURSION_DEPTH = 3` to prevent runaway nesting
+  - Nested items now skip `the_content` filter, using `wp_kses_post()` instead
+  - Nested data loading (albums within artists, tracks within albums) is now properly bounded
+
+### Changed
+
+- Made `get_artist_data()`, `get_album_data()`, `get_track_data()`, and `get_playlist_data()` public methods in TemplateLoader (previously private but called externally)
+- These methods now accept both `int` post IDs and `WP_Post` objects for flexibility
+- Added `$load_nested` parameter to control whether nested items are fully loaded or just counted
+
+## [0.4.0] - 2026-01-29
+
+### Added
+
+- Gitea Actions CI/CD pipeline for automated release package creation
+  - Triggered by `v*` tags
+  - PHP 8.3 environment with production dependencies
+  - Automatic translation compilation (.po to .mo)
+  - Version verification (plugin version must match tag)
+  - WordPress-compliant zip structure
+  - SHA256 checksum generation
+  - Package structure verification
+  - Changelog extraction for release notes
+  - Automatic Gitea release creation with attachments
+  - Pre-release detection for tags containing `-`
+
+## [0.3.0] - 2026-01-29
+
+### Added
+
+- License management integration using `magdev/wc-licensed-product-client` package
+- Tabbed settings page with License, Default Settings, and Integrations tabs
+- License validation and activation via AJAX with real-time status updates
+- License status banner showing current license state and expiration
+- License checks for frontend components (unlicensed sites show message instead of content)
+
+### Changed
+
+- Reorganized settings page into three tabs for better organization
+- Frontend features (player, shortcodes, ActivityPub) now require valid license
+- Admin/backend functionality works regardless of license status
+
+### Security
+
+- Server secret stored securely in WordPress options
+- HMAC signature verification for license server responses
+- Nonce verification for all license AJAX operations
+
+## [0.2.0] - 2026-01-28
+
+### Added
+
+- Settings and Dashboard links on the WordPress Plugins page for quick access
+- Comprehensive user guide (`USERGUIDE.md`) covering installation, configuration, and all features
+
 ## [0.1.1] - 2026-01-28

 ### Create releases
 
+**CRITICAL: NEVER build release packages locally! All releases are built automatically by the CI/CD pipeline (Gitea Actions) when a tag is pushed. Local builds can corrupt the development environment and create inconsistent packages.**
+
+To create a release:
+
+1. Update version in `wp-fedistream.php` (both header and constant)
+2. Update `CHANGELOG.md` with release notes
+3. Commit changes to `main` branch
+4. Create annotated tag: `git tag -a v0.6.0 -m "Release v0.6.0"`
+5. Push: `git push origin main --tags`
+6. CI/CD will automatically build and publish the release

+#### CI/CD Build Details (for reference only)
+
+The following details describe what the CI/CD pipeline does - DO NOT run these locally:
+
 - The `vendor/` directory MUST be included in releases (Dependencies required for runtime)
-- **Don't create any release files until version 0.1.x and up!**
+- Build `vendor/` for the MINIMUM supported PHP version (8.3.0)
-- **CRITICAL**: Build `vendor/` for the MINIMUM supported PHP version, not the development version
+- WordPress requires plugins in a subdirectory structure
-  - Use `composer config platform.php 8.3.0` before building release packages
+- Symlinks are excluded from packages
-  - Run `composer update --no-dev --optimize-autoloader` to rebuild dependencies
-- **CRITICAL**: WordPress requires plugins in a subdirectory structure
-  - Run zip from the `plugins/` parent directory, NOT from within the plugin directory
-  - Package must extract to `wp-fedistream/` subdirectory with main file at `wp-fedistream/wp-fedistream.php`
-  - Correct command: `cd /wp-content/plugins/ && zip -r wp-fedistream/releases/wp-fedistream-x.x.x.zip wp-fedistream ...`
-  - Wrong: Running zip from inside the plugin directory creates files at root level
-- **CRITICAL**: Exclude symlinks explicitly - zip follows symlinks by default
-  - Always use `-x "wp-fedistream/wp-core" -x "wp-fedistream/wp-core/*" -x "wp-fedistream/wp-plugins" -x "wp-fedistream/wp-plugins/*"` to exclude development symlinks
-  - Otherwise the entire linked directory contents will be included in the package
-- Exclusion patterns must match the relative path structure used in zip command
-- Always verify the package structure with `unzip -l` before distribution
-  - Check all files are prefixed with `wp-fedistream/`
-  - Verify main file is at `wp-fedistream/wp-fedistream.php`
-  - Check for duplicate entries (indicates multiple builds in same archive)
-- Test installation on the minimum supported PHP version before final deployment
 - Releases are stored in `releases/` including checksums
-- Track release changes in a single `CHANGELOG.md` file
+
-- Bump the version number to either bugfix release versions or on new features minor release versions
 - **CRITICAL**: WordPress reads version from TWO places - BOTH must be updated:
   1. Plugin header comment `Version: x.x.x` (line ~6 in wc-licensed-product.php) - WordPress uses THIS for admin display
   2. PHP constant `WP_FEDISTREAM_VERSION` (line ~28) - Used internally by the plugin

+#### CI/CD Pipeline (Gitea Actions)
+
+Automated release packages are created via Gitea Actions when a tag matching `v*` is pushed:
+
+**Workflow:** `.gitea/workflows/release.yml`
+
+**Trigger:** Push tag `vX.X.X` to repository
+
+**Steps:**
+
+1. Checkout code
+2. Setup PHP 8.3 with required extensions
+3. Install production Composer dependencies
+4. Compile translations (.po to .mo)
+5. Verify plugin version matches tag version
+6. Build release zip with proper WordPress structure
+7. Generate SHA256 checksums
+8. Verify package structure
+9. Extract changelog for release notes
+10. Create Gitea release with attachments
+
+**Required Secret:** `GITEA_TOKEN` - Personal access token with release permissions
+
+**Pre-release Detection:** Tags containing `-` (e.g., `v1.0.0-beta`) are marked as pre-release
+
+**To create a release:**
+
+```bash
+# Ensure version is updated in wp-fedistream.php (both header and constant)
+git checkout main
+git merge dev
+git tag -a v0.4.0 -m "Release v0.4.0"
+git push origin main --tags
+```
+
+The pipeline will automatically build and publish the release package.

+### 2026-01-28 - Bugfix v0.1.1 and Feature v0.2.0
+
+**Summary:** Fixed WooCommerce integration timing bug, added plugin action links and user guide.
+
+**v0.1.1 - Bugfix:**
+
+- Fixed WooCommerce product types not appearing in product selector
+- Root cause: `Integration` constructor hooked `check_woocommerce` to `plugins_loaded` priority 5, but class was instantiated at priority 10 (too late)
+- Solution: Call `check_woocommerce()` directly in constructor
+
+**v0.2.0 - Features:**
+
+- Added Dashboard and Settings links to WordPress Plugins page
+- Created comprehensive `USERGUIDE.md` covering all features
+
+**Files Modified:**
+
+- `includes/WooCommerce/Integration.php` - Fixed hook timing
+- `includes/Plugin.php` - Added `add_plugin_action_links()` method
+
+**Files Created:**
+
+- `USERGUIDE.md` - Comprehensive user documentation
+
+**Notes:**
+
+- All releases pushed to origin (v0.1.1 and v0.2.0 tags)
+- Markdown linting fixes applied to USERGUIDE.md
+
+### 2026-01-29 - License Management v0.3.0

+**Summary:** Implemented license management integration and reorganized settings page into tabs.
+
+**Features:**
+
+- License management using `magdev/wc-licensed-product-client` package
+- Tabbed settings page: License, Default Settings, Integrations
+- License validation and activation via AJAX
+- License status banner with expiration display
+- Frontend license checks (unlicensed sites show message instead of content)
+- Admin/backend works regardless of license status
+
+**License Behavior:**
+
+- Backend (admin): Full access always
+- Frontend (player, shortcodes, ActivityPub): Requires valid license
+
+**Files Created:**
+
+- `includes/License/Manager.php` - License management wrapper class
+
+**Files Modified:**
+
+- `composer.json` - Added VCS repository and `magdev/wc-licensed-product-client` dependency
+- `includes/Plugin.php` - Tabbed settings page, license manager initialization, conditional frontend loading
+- `includes/Installer.php` - Added default license options
+- `includes/Frontend/Shortcodes.php` - Added unlicensed mode support
+- `includes/Frontend/Ajax.php` - Added license checks to public AJAX endpoints
+- `assets/js/admin.js` - License validation AJAX handlers
+- `assets/css/admin.css` - Tab and license status styling
+- `wp-fedistream.php` - Version bump to 0.3.0
+- `CHANGELOG.md` - Added v0.3.0 entry
+
+**Notes:**
+
+- Package name is `magdev/wc-licensed-product-client` (not `wc-license-product-client`)
+- Uses Symfony HTTP Client via the license client package
+- License validation cached for 24 hours using WordPress transients
+
+### 2026-01-29 - CI/CD Pipeline v0.4.0
+
+**Summary:** Added Gitea Actions workflow for automated release package creation with multiple iterations to fix CI issues.

+- SHA256 checksum generation
+- Package structure verification
+- Changelog extraction for release notes
+- Automatic Gitea release creation via API
+- Pre-release detection for tags containing `-`
+
+**Files Created:**
+
+- `.gitea/workflows/release.yml` - CI/CD release pipeline
+- `.gitmodules` - Git submodule configuration
+- `lib/wc-licensed-product-client/` - Submodule for private dependency
+
+**Files Modified:**
+
+- `CLAUDE.md` - Added CI/CD documentation and updated directory structure
+- `CHANGELOG.md` - Added v0.4.0 entry

+2. Private repo network issue - use git submodule with relative URL (`../wc-licensed-product-client.git`)
+3. Composer path repository for submodule dependency
+4. `msgfmt` not found - install gettext package
+5. SIGPIPE error (exit 141) - use `set +o pipefail` and `|| true`
+
+**Notes:**
+
+- Requires `SRC_GITEA_TOKEN` secret configured in repository settings
+- Uses `shivammathur/setup-php@v2` for PHP setup
+- Uses Gitea API directly for release creation (not GitHub Actions)
+- Submodule uses relative URL for CI compatibility
+- Composer symlinks from `lib/wc-licensed-product-client` to vendor
+
+### 2026-02-02 - Memory Leak Investigation v0.4.1 through v0.4.9
+
+**Summary:** Investigated memory exhaustion issue when WP FediStream is used with WP Prometheus plugin. Multiple fix attempts were made but the root cause remains unresolved.
+
+**Problem:**
+
+- PHP Fatal error: Allowed memory size exhausted (1GB)
+- Error locations varied: Twig StagingExtension.php, Environment.php, ExtensionSet.php, WordPress class-wp-hook.php
+- Only occurs when WP Prometheus plugin is also active
+- Suspected infinite recursion through WordPress hook system
+
+**Fix Attempts (v0.4.1 - v0.4.8):**
+
+1. **v0.4.1** - Added recursion depth tracking in `get_post_data()`, skip `the_content` filter at depth > 1
+2. **v0.4.2** - Added `$in_shortcode_context` flag, all shortcode render methods enter context before data loading
+3. **v0.4.3** - Changed boolean to counter (`$shortcode_context_depth`), added context to `template-wrapper.php`
+4. **v0.4.4** - Fixed `get_the_excerpt()` which internally triggers `the_content` filter
+5. **v0.4.5** - Added render depth tracking in `Plugin::render()`, strip shortcodes from content
+6. **v0.4.6** - Added `$loading_page_template` flag to block shortcode rendering during page template loading
+7. **v0.4.7** - Added `$rendering_main_template` hard lock in `Plugin::render()`, reduced MAX_RENDER_DEPTH to 2
+8. **v0.4.8** - Nuclear option: ALWAYS skip `the_content` filter (didn't work, reverted)
+
+**v0.4.9 - Current State:**
+
+- Reverted nuclear option
+- Kept all other protections in place
+- Issue documented in README.md as known incompatibility
+
+**Files Modified:**
+
+- `includes/Frontend/TemplateLoader.php` - Multiple recursion protection mechanisms
+- `includes/Frontend/Shortcodes.php` - Shortcode context entry, page template loading check
+- `includes/Frontend/template-wrapper.php` - Page template loading flag, main template render flag
+- `includes/Plugin.php` - Render depth tracking, main template rendering lock
+- `README.md` - Added Known Issues section
+
+**Protection Mechanisms in Place:**
+
+1. `$recursion_depth` counter in `get_post_data()` (max 3)
+2. `$shortcode_context_depth` counter for nested shortcodes
+3. `$loading_page_template` flag blocks shortcode rendering during page load
+4. `$rendering_main_template` flag in `Plugin::render()` blocks parallel renders
+5. `MAX_RENDER_DEPTH = 2` in `Plugin::render()`
+6. Skip `the_content` and `get_the_excerpt()` when in protected context
+7. Strip shortcodes from content when skipping content filter
+
+**Key Learnings:**
+
+- `get_the_excerpt()` internally calls `apply_filters('the_content', ...)` when generating auto-excerpts
+- `the_content` filter triggers `do_shortcode()` which can cause recursive shortcode processing
+- WordPress hook system (class-wp-hook.php) can itself be the recursion point
+- The interaction between FediStream and WP Prometheus appears to be at a fundamental WordPress level
+
+**Status:** RESOLVED - Issue was fixed in WP Prometheus plugin, removed from known incompatibilities
+
+### 2026-02-02 - Prometheus Metrics & License Bypass v0.5.0/v0.5.1
+
+**Summary:** Added Prometheus metrics integration and localhost license bypass for development.
+
+**v0.5.0 - Prometheus Metrics Integration:**
+
+- Created `includes/Prometheus/Integration.php` with comprehensive metrics collection
+- Content metrics: `fedistream_content_total`, `fedistream_genres_total`, `fedistream_moods_total`
+- Engagement metrics: `fedistream_plays_total`, `fedistream_plays_today`, `fedistream_favorites_total`, `fedistream_local_follows_total`, `fedistream_listening_history_entries`
+- User metrics: `fedistream_users_with_library`, `fedistream_users_following_artists`, `fedistream_notifications_total`, `fedistream_notifications_pending`
+- WooCommerce metrics (conditional): `fedistream_purchases_total`, `fedistream_customers_total`, `fedistream_products_total`
+- ActivityPub metrics (conditional): `fedistream_activitypub_followers_total`, `fedistream_activitypub_followers_by_artist`, `fedistream_activitypub_reactions_total`
+- New setting in Integrations tab to enable/disable
+- Uses `wp_prometheus_collect_metrics` action hook
+
+**v0.5.1 - Localhost License Bypass:**
+
+- Added `is_localhost()` method to License Manager
+- Bypasses license check on: `localhost`, `127.0.0.1`, `::1`
+- Also bypasses for TLDs: `.local`, `.test`, `.localhost`, `.dev.local`
+- Allows full plugin functionality during local development
+
+**Files Created:**
+
+- `includes/Prometheus/Integration.php` - Metrics collection class
+- `includes/Prometheus/index.php` - Security file
+
+**Files Modified:**
+
+- `includes/Plugin.php` - Added Prometheus integration, settings toggle, `is_prometheus_active()` method
+- `includes/Installer.php` - Added `wp_fedistream_enable_prometheus` default option
+- `includes/License/Manager.php` - Added `is_localhost()` method, bypass in `is_license_valid()`
+- `README.md` - Removed known incompatibility section, updated version badge
+
+**Integration Pattern:**
+
+Follows same pattern as WooCommerce/ActivityPub integrations:
+
+```php
+if (get_option('wp_fedistream_enable_prometheus', 0) && $this->is_prometheus_active()) {
+    new PrometheusIntegration();
+}
+```
+
+**Notes:**
+
+- WP Prometheus memory leak issue was fixed in WP Prometheus itself
+- Metrics use simple COUNT queries for performance
+- ActivityPub followers limited to top 10 to avoid cardinality explosion
+- Default disabled (opt-in via Settings > Integrations)
+
+### 2026-02-02 - Native PHP Templates v0.6.0
+
+**Summary:** Removed Twig dependency and converted all templates to native PHP for improved performance and reduced dependencies.
+
+**Changes:**
+
+- Removed `twig/twig` from composer.json dependencies
+- Converted all 25 Twig templates to native PHP templates
+- Updated `Plugin.php` with new `render()` method using PHP include with output buffering
+- Added `render_partial()` helper method for including partials from within templates
+- Added `get_template_path()` method supporting theme overrides via `fedistream/` directory
+- Reduced plugin package size by removing Twig and its dependencies
+
+**Files Modified:**
+
+- `includes/Plugin.php` - Removed Twig initialization, new native PHP render methods
+- `includes/Frontend/template-wrapper.php` - Updated docblock
+- `composer.json` - Removed `twig/twig` dependency
+
+**Templates Created (25 PHP files replacing Twig):**
+
+- `templates/partials/` - card-artist.php, card-album.php, card-track.php, card-playlist.php
+- `templates/single/` - artist.php, album.php, track.php, playlist.php
+- `templates/archive/` - artist.php, album.php, track.php, playlist.php, taxonomy.php
+- `templates/shortcodes/` - artist.php, album.php, track.php, playlist.php, player.php, releases-grid.php, tracks-list.php, artists-grid.php
+- `templates/widgets/` - recent-releases.php, popular-tracks.php, featured-artist.php, now-playing.php
+
+**Templates Deleted (25 Twig files):**
+
+- All `.twig` files in templates directory
+
+**Benefits:**
+
+- No external template engine dependency
+- Improved performance (no Twig compilation)
+- Native WordPress template overriding support
+- Smaller plugin package size
+- Simpler debugging with standard PHP
+
+**Critical Learning - NEVER Build Local Releases:**
+
+- Attempted to run `composer update --no-dev` locally for release building
+- This corrupts the development environment and creates inconsistent packages
+- **All releases must be built by CI/CD pipeline only**
+- The "Create releases" section in this document has been updated with this critical instruction
+- To create a release: commit, tag, push - CI/CD handles the rest

+## ActivityPub Integration
+

+
+### Requirements for ActivityPub integration
+
+Install and activate the [ActivityPub plugin](https://wordpress.org/plugins/activitypub/) from WordPress.org.
+
+### How It Works
+
+1. Each artist becomes an ActivityPub actor (like a Mastodon account)
+2. Fediverse users can follow artists using their handle: `@artist-slug@your-domain.com`
+3. When you publish new albums or tracks, announcements are sent to followers
+4. Followers can like and boost your releases, which shows on your site
+
+### Artist Discovery (Webfinger)
+
+Artists can be discovered via Webfinger:
+
+```txt
+https://your-site.com/.well-known/webfinger?resource=acct:artist-name@your-site.com
+```
+
+### Activity Types
+
+| Activity | When Sent |
+| ---------- | ----------- |
+| Create | New album or track published |
+| Update | Album or track updated |
+| Delete | Content removed |
+| Follow/Accept | New follower confirmed |
+
+### Viewing Followers
+
+Artist followers are displayed on the artist's admin page under the Followers meta box.
+
+---
+
