​

Removed

• Peer-level messages

​

Changed

• Rearranged configuration values (LLM, Deriver, Dialectic, History->Summary)

​

Fixed

• Groq API client to use the Async library

​

Fixed

• Migration/provision scripts did not have correct database connection arguments, causing timeouts

​

Fixed

• Bug that causes runtime error when Sentry flags are enabled

​

Fixed

• Database initialization was misconfigured and led to provision_db script failing: switch to consistent working configuration with transaction pooler

​

Added

• Ergonomic SDKs for Python and TypeScript (uses Stainless underneath)
• Deriver Queue Status endpoint
• Complex arbitrary filters on workspace/session/peer/message
• Message embedding table for full semantic search

​

Changed

• Overhauled documentation
• BasedPyright typing for entire project
• Resource filtering expanded to include logical operators

​

Fixed

• Various bugs
• Use new config arrangement everywhere
• Remove hardcoded responses

​

Added

• Ability to get a peer’s working representation
• Metadata to all data primitives (Workspaces, Peers, Sessions, Messages)
• Internal metadata to store Honcho’s state no longer exposed in API
• Batch message operations and enhanced message querying with token and message count limits
• Search and summary functionalities scoped by workspace, peer, and session
• Session context retrieval with summaries and token allocatio
• HNSW Index for Documents Table
• Centralized Configuration via Environment Variables or config.toml file

​

Changed

• New architecture centered around the concept of a “peer” replaces the former “app”/“user”/“session” paradigm
• Workspaces replace “apps” as top-level namespace
• Peers replace “users”
• Sessions no longer nested beneath peers and no longer limited to a single user-assistant model. A session exists independently of any one peer and peers can be added to and removed from sessions.
• Dialectic API is now part of the Peer, not the Session
• Dialectic API now allows queries to be scoped to a session or “targeted” to a fellow peer
• Database schema migrated to adopt workspace/peer/session naming and structure
• Authentication and JWT scopes updated to workspace/peer/session hierarchy
• Queue processing now works on ‘work units’ instead of sessions
• Message token counting updated with tiktoken integration and fallback heuristic
• Queue and message processing updated to handle sender/target and task types for multi-peer scenarios

​

Fixed

• Improved error handling and validation for batch message operations and metadata
• Database Sessions to be more atomic to reduce idle in transaction time

​

Removed

• Metamessages removed in favor of metadata
• Collections and Documents no longer exposed in the API, solely internal
• Obsolete tests for apps, users, collections, documents, and metamessages

​

Added

• Normalize resources to remove joins and increase query performance
• Query tracing for debugging

​

Changed

• /list endpoints to not require a request body
• metamessage_type to label with backwards compatability
• Database Provisioning to rely on alembic
• Database Session Manager to explicitly rollback transactions before closing the connection

​

Fixed

• Alembic Migrations to include initial database migrations
• Sentry Middleware to not report Honcho Exceptions

​

Added

• JWT based API authentication
• Configurable logging
• Consolidated LLM Inference via ModelClient class
• Dynamic logging configurable via environment variables

​

Changed

• Deriver & Dialectic API to use Hybrid Memory Architecture
