-## [8.0.0] - 2025-12-14
+## [7.2.3] - 2025-12-15
 
-### Fixed
+## Bug Fixes
 
-**Timeline MCP Tools Parameter Bug**
+- **Fix MCP server failures on plugin updates**: Add 2-second pre-restart delay in `ensureWorkerVersionMatches()` to give files time to sync before killing the old worker. This prevents the race condition where the worker restart happened too quickly after plugin file updates, causing "Worker service connection failed" errors.
 
-Fixed critical bug where timeline tools were completely non-functional due to parameter name mismatch between MCP layer and SearchManager. The tools now use correct parameter names:
-- `anchor` (was incorrectly `anchor_id`)
-- `depth_before` (was incorrectly `before`)
-- `depth_after` (was incorrectly `after`)
-- `type` (was incorrectly `obs_type` in timeline tool only)
+## Changes
 
-**Affected Tools:** `timeline`, `get_context_timeline`, `get_timeline_by_query`
+- Add `PRE_RESTART_SETTLE_DELAY` constant (2000ms) to `hook-constants.ts`
+- Add delay before `ProcessManager.restart()` call in `worker-utils.ts`
+- Fix pre-existing bug where `port` variable was undefined in error logging
 
-**Impact:** These tools were previously broken and would fail with "Cannot read properties of undefined (reading 'length')" errors. They now work correctly with the proper parameter names that match the underlying SearchManager implementation.
+## [7.2.2] - 2025-12-15
 
-### Added
-- New `get_batch_observations` MCP tool for efficiently fetching multiple observations in a single request
-- Enhanced SessionStore methods for fetching prompts and session summaries by ID
+## Changes
 
-### Changed
-- Extracted magic numbers to constants (`RECENCY_WINDOW_DAYS`, `RECENCY_WINDOW_MS`)
-- Replaced debug logging calls with proper logger methods
+- **Refactor:** Consolidate mem-search skill, remove desktop-skill duplication
+  - Delete separate `desktop-skill/` directory (was outdated)
+  - Generate `mem-search.zip` during build from `plugin/skills/mem-search/`
+  - Update docs with correct MCP tool list and new download path
+  - Single source of truth for Claude Desktop skill

+## [7.3.0] - 2025-12-15
+
+## Features
+
+- **Table-based search output**: Unified timeline formatting with cleaner, more organized presentation of search results grouped by date and file
+- **Simplified API**: Removed unused format parameter from MCP search tools for cleaner interface
+- **Shared formatting utilities**: Extracted common timeline formatting logic into reusable module
+
+## Changes
+
+- **Default model upgrade**: Changed default model from Haiku to Sonnet for better observation quality
+- **Removed fake URIs**: Replaced claude-mem:// pseudo-protocol with actual HTTP API endpoints for citations
+
+## Bug Fixes
+
+- Fixed undefined debug function calls in MCP server
+- Fixed skillPath variable scoping bug in instructions endpoint

+
+# Current State of Endless Mode
+
+## Core Concept
+
+Endless Mode is a **biomimetic memory architecture** that solves Claude's context window exhaustion problem. Instead of keeping full tool outputs in the context window (O(N²) complexity), it:
+
+- Captures compressed observations after each tool use
+- Replaces transcripts with low token summaries
+- Achieves O(N) linear complexity
+- Maintains two-tier memory: working memory (compressed) + archive memory (full transcript on disk, maintained by default claude code functionality)
+
+## Implementation Status
+
+**Status**: FUNCTIONAL BUT EXPERIMENTAL
+
+**Current Branch**: `beta/endless-mode` (ahead of main)
+
+**Recent Activity**:
+- Merged main branch changes
+- Resolved merge conflicts in save-hook, SessionStore, SessionRoutes
+- Updated documentation to remove misleading token reduction claims
+- Added important caveats about beta status
+
+## Key Architecture Components
+
+1. **Pre-Tool-Use Hook** - Tracks tool execution start, sends tool_use_id to worker
+2. **Save Hook (PostToolUse)** - **CRITICAL**: Blocks until observation is generated (110s timeout), injects compressed observation back into context
+3. **SessionManager.waitForNextObservation()** - Event-driven wait mechanism (no polling)
+4. **SDKAgent** - Generates observations via Agent SDK, emits completion events
+5. **Database** - Added `tool_use_id` column for observation correlation
+
+## Configuration
+
+```json
+{
+  "CLAUDE_MEM_ENDLESS_MODE": "false",  // Default: disabled
+  "CLAUDE_MEM_ENDLESS_WAIT_TIMEOUT_MS": "90000"  // 90 second timeout
+}
+```
+
+**Enable via**: Manual checkout of beta branch (see instructions below)
+
+## Flow
+
+```
+Tool Executes → Pre-Hook (track ID) → Tool Completes →
+Save-Hook (BLOCKS) → Worker processes → SDK generates observation →
+Event fired → Hook receives observation → Injects markdown →
+Clears input → Context reduced
+```
+
+## Known Limitations
+
+From the documentation:
+- ⚠️ **Slower than standard mode** - Blocking adds latency
+- ⚠️ **Still in development** - May have bugs
+- ⚠️ **Not battle-tested** - New architecture
+- ⚠️ **Theoretical projections** - Efficiency gains not yet validated in production
+
+## What's Working
+
+- ✅ Synchronous observation injection
+- ✅ Event-driven wait mechanism
+- ✅ Token reduction via input clearing
+- ✅ Database schema with tool_use_id
+- ✅ Web UI for version switching
+- ✅ Graceful timeout fallbacks
+
+## What's Not Ready
+
+- ❌ Production validation of token savings
+- ❌ Comprehensive test coverage
+- ❌ Stable channel release
+- ❌ Performance benchmarks
+- ❌ Long-running session data
+
+## How to Try Endless Mode
+
+Endless Mode is currently only available on the beta branch. To try it:
+
+```bash
+# Navigate to your claude-mem installation
+cd ~/.claude/plugins/marketplaces/thedotmack/
+
+# Checkout the beta branch
+git checkout beta/endless-mode
+
+# Install dependencies
+npm install
+
+# Restart the worker
+npm run worker:restart
+```
+
+**To return to stable:**
+
+```bash
+cd ~/.claude/plugins/marketplaces/thedotmack/
+git checkout main
+npm install
+npm run worker:restart
+```
+
+## Summary
+
+The implementation is architecturally complete and functional, but remains experimental pending production validation of the theoretical efficiency gains.
