 ## [Unreleased]
 
+### Added
+
+- **ICM (Infinite Context Memory)**: New MCP memory server section after Kairn (~line 11365) — Rust single binary, zero deps, Homebrew install, dual architecture (episodic decay Memories + permanent knowledge graph Memoirs), 9 typed relation types, auto-extraction 3 layers, 14 editor clients. Score 3/5 — recommended as Rust-native alternative when Python dependency management is a friction point. Includes explicit license callout (Source-Available, free ≤20 people) and vendor-reported benchmark flags.
+- **Comparison matrix update**: Added ICM column to MCP memory stack matrix (Runtime + License rows added for all tools)

 ## 2.1.x Series (January-March 2026)
 
+### v2.1.76 (2026-03-14)
+
+- **New**: ⭐ MCP elicitation support — MCP servers can now request structured input mid-task via an interactive dialog (form fields or browser URL)
+- **New**: `Elicitation` and `ElicitationResult` hooks to intercept and override MCP input responses before they're sent back to the server
+- **New**: `PostCompact` hook that fires after compaction completes
+- **New**: `-n` / `--name <name>` CLI flag to set a display name for the session at startup
+- **New**: `worktree.sparsePaths` setting for `claude --worktree` in large monorepos — check out only needed directories via git sparse-checkout
+- **New**: `/effort` slash command to set model effort level
+- **Fixed**: Deferred tools (loaded via `ToolSearch`) losing their input schemas after conversation compaction — array and number parameters were being rejected with type errors
+- **Fixed**: Auto-compaction retrying indefinitely after consecutive failures — circuit breaker now stops after 3 attempts
+- **Fixed**: `Bash(cmd:*)` permission rules not matching when a quoted argument contains `#`
+- **Fixed**: Slash commands showing "Unknown skill"
+- **Fixed**: Plan mode asking for re-approval after the plan was already accepted
+- **Fixed**: Voice mode swallowing keypresses while a permission dialog or plan editor was open
+- **Fixed**: `/voice` not working on Windows when installed via npm
+- **Fixed**: Bridge sessions failing to recover after extended WebSocket disconnects
+- **Improved**: `--worktree` startup performance by reading git refs directly, skipping redundant `git fetch`
+- **Improved**: Killing a background agent now preserves its partial results in the conversation context
+- **Improved**: Model fallback notifications — now always visible with human-friendly model names
+- **Improved**: Stale worktree cleanup — worktrees left behind after interrupted parallel runs are automatically cleaned up
+- **Improved**: Blockquote readability on dark terminal themes — italic with left bar instead of dim
+- **Updated**: `--plugin-dir` now accepts one path only; use repeated flags for multiple directories
+- **VSCode**: Fixed gitignore patterns containing commas silently excluding entire filetypes from the `@`-mention file picker
+
 ### v2.1.75 (2026-03-13)
 
 - **New**: ⭐ 1M context window for Opus 4.6 now enabled by default for Max, Team, and Enterprise plans (previously required extra usage)
