+## [v1.110.0] - 2026-07-15
+
+This release adds dynamic MCP HTTP headers, new shell safety policies, per-model custom pricing, and cache-stable dynamic prompts, along with fixes for elicitation delivery and session cost tracking.
+
+## What's New
+
+- Adds dynamic MCP HTTP headers via a header factory, enabling context-aware HTTP header resolution instead of static headers fixed at startup
+- Adds a `safe-auto` safety policy for shell operations, providing a middle ground between prompting for every tool call and `--yolo` mode; safe calls beyond shell are auto-approved under this policy, with an opt-in `safer` mode available via `approve-safer` resume
+- Adds an optional `cost` block to model configuration, allowing explicit per-model token pricing for custom, locally-hosted, or uncatalogued models
+- Adds opt-in cache-stable dynamic prompts (`cache_stable_prompts` user setting), persisting frozen instruction snapshots and appending chronological updates when trusted context changes
+
+## Bug Fixes
+
+- Fixes elicitation requests from concurrent background jobs being silently dropped and blocking the requesting handler indefinitely
+- Fixes session cost dropping after compaction (e.g., from $49 to $12) by keeping cost monotonic across compaction and preserving cost accounting across reload
