+## [v1.23.6] - 2026-02-23
+
+This release improves cost tracking accuracy, enhances session management, and fixes several UI and functionality issues.
+
+## What's New
+
+- Adds tab completion for /commands dialog
+- Adds mouse support for selecting and opening sessions in the sessions dialog
+
+## Improvements
+
+- Computes session cost from messages instead of accumulating on session for better accuracy
+- Includes compaction cost in /cost dialog
+- Displays original YAML model names in sidebar instead of resolved aliases
+- Improves emoji copying support by reversing clipboard copy order (OSC52 first, then pbcopy fallback)
+
+## Bug Fixes
+
+- Fixes token usage percentage display during and after agent transfers
+- Fixes session forking and costs calculation
+- Fixes actual provider display for alloy models in sidebar (was showing wrong provider)
+- Restores ctrl-1, ctrl-2... shortcuts for quick agent selection
+- Fixes NewHandler panic on parameterless tool calls
+
+## Technical Changes
+
+- Consolidates TokenUsage event constructors
+- Removes dead UpdateLastAssistantMessageUsage method
+- Emits TokenUsageEvent on session restore for context percentage display
+- Emits TokenUsageEvent after compaction so sidebar cost updates
+- Adds e2e tests on binaries for CLI plugin execution
+- Creates ~/.docker/cli-plugins directory if it doesn't exist
