ChuckandClaude Opus 5.5 2601cb4cbb chore(deprecation): remove the 35 APIs deprecated for 3.8.0 (#708)
* chore(deprecation): remove the 35 APIs deprecated for 3.8.0

The usage scan (docs/DEPRECATIONS_3.8.md, regenerated 2026-10-01 and
committed here) finds no call or override of any of them in the 46
monorepo plugins or the 8 third-party plugins plugins.json lists; the
only core callers were other deprecated methods removed alongside.

- CacheManager: 13 methods, plus the private helpers only
  has_data_changed used (_has_*_changed, _is_market_open).
- DisplayManager: 7 methods, plus WEATHER_COLORS and the private
  _draw_sun/_cloud/_rain/_snow/_storm helpers only the icon methods used.
- FontManager: 14 methods, plus size_tokens, _save_overrides and
  _clear_plugin_font_cache. font_overrides and _load_overrides stay:
  resolve_font() still applies config/font_overrides.json.
  performance_stats stays: get_font() keeps it and tests read it.
- PluginManager.get_enabled_plugins.

test_deprecation.py pins only the two 3.9.0 markers now; the scanner
tests run against a stand-in core instead of the real markers. The
memory-tier tests read stats through log_memory_cache_stats() and the
component, and the test of the removed _clear_plugin_font_cache goes.
Docs drop the removed methods' reference entries; the Deprecated APIs
table becomes "Removed in 3.8.0". CHANGELOG gains a Removed section.

* chore(deprecation): drop the test harness's copies of the removed icon methods

VisualTestDisplayManager still drew weather icons that DisplayManager no
longer has, so a plugin's visual tests could pass on calls that raise
AttributeError on the real display. Its draw_sun/draw_cloud/draw_rain/
draw_snow/draw_weather_icon/draw_text_with_icons, WEATHER_COLORS and the
private helpers go, with the tests that exercised them. The CHANGELOG's
Deprecations entries no longer say nothing is removed.

LEDMatrix Documentation

This directory contains guides, references, and architectural notes for the LEDMatrix project. If you are setting up a Pi for the first time, start with the project root README — it covers hardware, OS imaging, and the one-shot installer. The pages here go deeper.

I'm a new user

  1. GETTING_STARTED.md — first-time setup walkthrough
  2. WEB_INTERFACE_GUIDE.md — using the web UI
  3. PLUGIN_STORE_GUIDE.md — installing and managing plugins
  4. WIFI_NETWORK_SETUP.md — WiFi and AP-mode setup
  5. TROUBLESHOOTING.md — common issues and fixes (PERMISSIONS.md for "Permission denied")
  6. SSH_UNAVAILABLE_AFTER_INSTALL.md — recovering SSH after install
  7. CONFIG_DEBUGGING.md — diagnosing config problems
  8. LOW_MEMORY_BOARDS.md — Pi Zero 2 W / 3B+ / 1GB Pi 4 memory limits

I want to write a plugin

Start here:

  1. PLUGIN_DEVELOPMENT_GUIDE.md — end-to-end workflow
  2. PLUGIN_QUICK_REFERENCE.md — cheat sheet
  3. PLUGIN_API_REFERENCE.md — display, cache, and plugin-manager APIs
  4. PLUGIN_ERROR_HANDLING.md — error-handling patterns
  5. DEV_PREVIEW.md — preview plugins on your dev machine without a Pi
  6. EMULATOR_SETUP_GUIDE.md — running the matrix emulator

Contributing to the docs

  • Markdown only, professional tone, minimal emoji.
  • Prefer adding to an existing page over creating a new one. If you add a new page, link it from this index in the section it belongs to.
  • If a page becomes obsolete, delete it (it stays in the repository history) and fix the links to it; test/test_doc_links.py fails on broken relative links.
  • Keep examples runnable — paths, commands, and config keys here should match what's actually in the repo.
