 # Changelog
 
+## 0.9.0 - 2026-04-24
+
+### Added (CLI)
+- **Claude Max 5x plan preset.** `codeburn plan claude-max-5x` sets a $100/month budget for heavy Claude Code users.
+
+### Fixed (CLI)
+- **Cursor provider failed on newer versions.** Cursor 0.50+ stores session data in `agentKv:blob:*` entries instead of `bubbleId:*`. Added fallback parser that extracts usage from the new format.
+- **Cursor-agent provider missed Composer 2 sessions.** Composer 2 stores transcripts in `agent-transcripts/<UUID>/<UUID>.jsonl` subdirectories instead of `.txt` files. Now scans both formats. Fixes #142.
+- **Codex showed wrong model names.** Model info is now extracted from `turn_context` entries, showing exact names like "GPT-5.4" instead of generic "GPT-5".
+- **Codex edit detection showed 0 edit turns.** Codex records file modifications as `patch_apply_end` events, not tool calls. Now tracks these events to enable one-shot rate and retry metrics.
+- **Compare chart bar colors didn't match legend.** Non-winning model bars were grayed out despite the legend showing both colors. Bars now always display their assigned colors.
+
+### Fixed (macOS menubar)
+- **Menubar icon invisible on macOS Tahoe (26.x).** Status item failed to render on macOS 26.4+ due to window server registration timing. Fixed by starting as regular app, activating, then switching to accessory mode after setup. Fixes #146.
+- **High CPU usage (~14%).** Removed duplicate refresh timer, increased LaunchAgent interval to 30s, added 5-second debounce on wake events.

 ## 0.8.9 - 2026-04-22
