pfUI/CHANGELOG.md

• Hard dependency on ClassicAPI — modern C_* namespaces and engine polyfills (focus, nameplates, GUIDs).
• TBC/Wrath/expansion plumbing removed; vanilla 1.12 + Turtle WoW only.
• Nameplate overhaul — GUID-keyed caches, per-tick allocation cuts, name-collision filtering, configurable name text position.
• Unit auras rebuilt on C_UnitAuras — replaces the old tooltip-scraping aura tracker with structured engine data, so buff/debuff durations, stack counts, and source attribution are accurate without polling.
• Equipment manager — new backport of Blizzard's gear-set UI, integrated into the character pane. Save, swap, and edit sets without a third-party addon.
• Bag sorting — new built-in feature (previously pfUI only deferred to third-party sorters).
• /focus and /clearfocus moved to ClassicAPI; /focusname retained in pfUI.
• questitem refactored onto C_QuestLog.
• updatenotify isolated to its own pfUI-brues addon-message prefix so we don't share traffic with upstream pfUI installs.
