## [0.5.0] - 2025-04-29
|
||
|
|
|
||
|
|
### Added
|
||
|
|
|
||
|
|
#### Multi-Profile Support
|
||
|
|
- **Profile-based usage tracking**: Added `profile` field to `session_usage` table for filtering statistics by profile
|
||
|
|
- **Profile-aware session management**: All sessions now track their originating profile (default, hermes, custom)
|
||
|
|
- **Group chat agent profiles**: Each agent can run with its own Hermes profile configuration
|
||
|
|
- **Cross-profile usage aggregation**: Usage stats page correctly filters by active profile
|
||
|
|
|
||
|
|
#### Group Chat Enhancements
|
||
|
|
- **Context compression with multi-profile**: Group chat compression now uses agent's own profile
|
||
|
|
- **Usage tracking for compression**: Token usage from context compression runs is recorded with room ID
|
||
|
|
- **Session profile mapping**: New `gc_session_profiles` table tracks ephemeral session to profile relationships
|
||
|
|
|
||
|
|
#### Single Chat Improvements
|
||
|
|
- **Ephemeral session cleanup**: Automatic deletion of temporary Hermes sessions after sync
|
||
|
|
- **User message persistence**: User messages are now properly saved to local database
|
||
|
|
- **Usage synchronization**: Token usage from Hermes sessions correctly syncs to local usage store
|
||
|
|
|
||
|
|
### Fixed
|
||
|
|
|
||
|
|
#### Token Estimation
|
||
|
|
- **Fixed overestimation**: Removed `senderName` from token calculation to avoid inflated estimates
|
||
|
|
- **Configurable estimation**: Token estimation now uses `charsPerToken` config instead of hardcoded value
|
||
|
|
- **Adjusted compression trigger**: Increased `charsPerToken` from 4 to 6 for more conservative estimation
|
||
|
|
- This prevents premature compression triggering in group chats
|
||
|
|
- Better matches actual LLM tokenization (~6-8 chars/token for English)
|
||
|
|
|
||
|
|
#### WSL Compatibility
|
||
|
|
- **Auto-detect WSL environment**: Database path automatically uses WSL local filesystem when detected
|
||
|
|
- **Improved SQLite settings**: Changed to WAL mode with `synchronous=NORMAL` and `busy_timeout=5000`
|
||
|
|
- Fixes cross-filesystem write failures in WSL2 environments
|
||
|
|
- Better concurrency and reliability
|
||
|
|
|
||
|
|
#### Database Schema
|
||
|
|
- **Unified table initialization**: Created `initAllStores()` for consistent table creation across all stores
|
||
|
|
- **Session usage schema**: Added `id` PRIMARY KEY AUTOINCREMENT for better query performance
|
||
|
|
- **Production environment**: Set `NODE_ENV=production` in production start scripts for correct database path
|
||
|
|
|
||
|
|
#### Logging
|
||
|
|
- **Enhanced error logging**: Improved error messages in `syncFromHermes` with detailed context
|
||
|
|
- **Database path logging**: Added explicit logging of Hermes state.db path for debugging
|
||
|
|
|
||
|
|
### Changed
|
||
|
|
|
||
|
|
- **Default compression trigger**: Group chat rooms now default to 100,000 tokens (was 10,000)
|
||
|
|
- **Database location**: In WSL, database always uses `~/.hermes-web-ui/` to avoid cross-filesystem issues
|
||
|
|
|
||
|
|
### Technical Details
|
||
|
|
|
||
|
|
#### Database Tables
|
||
|
|
- `sessions`: Added `profile` field
|
||
|
|
- `session_usage`: Added `profile` field and `id` PRIMARY KEY
|
||
|
|
- `gc_pending_session_deletes`: Tracks profile-specific session cleanup
|
||
|
|
- `gc_session_profiles`: Maps ephemeral sessions to profiles and rooms
|
||
|
|
|
||
|
|
#### Code Organization
|
||
|
|
- Created `packages/server/src/db/hermes/init.ts`: Unified store initialization
|
||
|
|
- Updated `packages/server/src/db/index.ts`: WSL detection and improved SQLite settings
|
||
|
|
- Refactored `packages/server/src/services/hermes/context-engine/`: Better token estimation
|
||
