Release Notes - v0.5.4.dev1

Release Date: 2026-03-05
Changes: v0.5.4.dev1 → dev

Summary

This is a developer preview release (v0.5.4.dev1) focused on iterative quality, performance, and developer ergonomics. It contains targeted feature additions for import and search, several reliability fixes, and internal refactors to make future releases faster and safer to ship.

Highlights

• Developer preview release with targeted improvements and fixes
• Faster ingestion and sync, reducing delay when adding memories
• Improved search relevance and new filtering options for more accurate results
• Stability and bug fixes for memory creation, deletion, and CLI workflows
• Internal refactoring and dependency upgrades that improve maintainability and prepare for upcoming features

Breaking Changes

• No breaking changes in this dev preview. Existing integrations and APIs should continue to work as before.

New Features

• Bulk import CLI: a new import mode for faster, batched ingestion of large memory sets (CLI-focused developer tool).
• Search filters: added basic tag and date-range filtering to search queries to help narrow results.
• Per-collection ingestion throttling: optional rate limits to smooth ingestion spikes and reduce timeouts during heavy load.

Improvements

• Ingestion and sync performance: reduced latency when saving and syncing memories across the system, so newly added items appear faster.
• Search relevance: tweaks to ranking heuristics for more relevant results on common queries.
• Stability: more robust handling around memory deletion and duplicate detection to avoid orphaned data.
• Developer experience: clearer CLI messages, improved debug logs, and small SDK ergonomics improvements to speed up development and troubleshooting.

Bug Fixes

• Fixed an issue that could create duplicate memories under certain concurrent ingestion patterns.
• Resolved cases where memory deletion left partial state, causing inconsistent search results.
• Fixed CLI export formatting bugs that occasionally corrupted exported files.
• Addressed intermittent memory retrieval failures that surfaced under high load.

Technical Changes

• Indexing pipeline refactor: internal reorganization of the memory indexing code to improve performance and make future features easier to add.
• Dependency upgrades: several internal libraries have been updated for security and performance—please run your usual test suite against the dev build.
• Expanded automated tests around ingestion and search to reduce regressions going forward.
• Improved logging: unified log format and additional diagnostic information to help troubleshooting.
