MemoryBear v0.3.9 Community Release Notes — Unstoppable Momentum

[keeees]

Release Date: June 24, 2026 | Codename: PoJun (破军 · Breaking the Vanguard)

This release pushes MemoryBear from feature accumulation toward platform-grade robustness. Memory reflection becomes more reliable, knowledge processing handles richer file types, and retrieval gets faster. Together with stronger entity relationships and the memory service's debut on the ModelScope MCP marketplace, this version sharpens both the depth and the reach of memory capabilities.

⚠️ Breaking Changes

• Removed endpoints: The synchronous-write /v1/memory/write/sync and asynchronous-read /v1/memory/read endpoints have been removed in this version. Please migrate to the current memory write/read endpoints before upgrading. If you need migration guidance, refer to the API documentation.
• Deprecation notice (removal in next version): The /v1/write/status (async write task status query) and /v1/read/status (async read task status query) endpoints will be removed in the next version. Please check whether your integration calls these endpoints and plan your migration accordingly.

🚀 I. Core Upgrade Overview

1. Memory Intelligence 🧠

• More Reliable Reflection: Memory reflection now executes more steadily and safely, sustaining stable performance even under heavy load so reflection results are produced consistently.
• Event Timeline Editing: The reflection engine can now add, update, and delete events on an entity's description timeline, dynamically enriching existing events, appending new ones, and removing outdated details based on user input.
• Multi-Relationship Entity Types: Build entity relationship networks across multiple dimensions, strengthening relationship analysis and surfacing latent associations.
• More Accurate Memory Extraction: Improved the accuracy of statement extraction and simplified its field structure for cleaner, more consistent results.
• Smarter Memory Compression: Refined the memory compression strategy to better preserve key information such as timestamps and important events, improving information completeness.
• More Precise Deduplication: Memory merging is now more precise — part-whole and subclass-superclass cases are no longer incorrectly merged, while genuine duplicates are consolidated reliably.
• Metadata Management: Memory metadata can now be correctly added, updated, and deleted, with more consistent structured management throughout the memory lifecycle.
• Express Retrieval Mode: A new high-speed memory retrieval mode optimized for latency-sensitive scenarios, delivering faster responses for real-time interaction.
• Trial-Run Memory Cleanup: Temporary memories generated during trial runs are now automatically cleaned up, preventing stale data accumulation and improving data quality.

2. Knowledge Base & Document Processing 📚

• Structured Data Parsing: Structured files such as JSON, Excel, and CSV are now parsed through a dedicated path separate from general text, improving tabular data parsing and processing quality.
• More Maintainable Chunking: The knowledge base chunking flow has been improved for greater stability and extensibility, making it easier to support more file types and chunking strategies going forward.
• Parent-Child Chunking Recognition: The system now uniformly determines and reports parent-child chunking mode (parent_child_mode), for more consistent chunking behavior.
• Structured Excel Parser: The new Excel parser recognizes sheets, merged cells, sub-table regions, and headers, converting Excel data into structured chunks with field semantics and provenance — improving Excel retrieval accuracy in RAG scenarios.

---

3. Application & Knowledge Recall ⚙️

• Object Storage Support: Added object storage capability for file storage, improving scalability and reliability.
• Unified Knowledge Recall: Workflow and Agent now share a unified knowledge-retrieval capability, delivering more consistent retrieval behavior across both and improving reuse.
• Navigation Rename: Renamed "Application Management" to "Agent Management" in the in-workspace left navigation bar.

---

4. API & Ecosystem Integration 🔌

• ModelScope MCP Marketplace: The memory MCP service is now listed on the ModelScope MCP marketplace, expanding ecosystem reach and making it easier to discover and use memory capabilities.
• End-Users Query API: Added /v1/dashboard/end_users, which paginates the user list and memory counts for a workspace using its API key.
• Streamlined API Key Onboarding: Creating an API key now returns the associated user identifiers in the same response, letting integrations complete identity mapping and memory association more quickly.

---

5. User Experience 🎨

• Knowledge Base Detail UI: Refined the action bar on the knowledge base detail page, adjusting the layout of operation entries.
• Workflow Canvas Layout: Moved the workflow orchestration action bar downward for a cleaner layout.

🧭 Looking Ahead

This release marks a turning point in MemoryBear's maturity. More reliable reflection, richer knowledge processing, and stronger storage together signal a shift from feature accumulation toward platform-grade robustness. The system is now better equipped to carry production workloads safely and steadily.

The introduction of express retrieval, multi-relationship entity modeling, and the ModelScope MCP listing point toward a broader trajectory: memory as an open, fast, and richly connected capability. By unifying knowledge recall across workflows and agents, MemoryBear is laying the groundwork for memory that is both deeper in understanding and wider in reach.

Looking ahead, we will deepen short-term and working memory by tying them more closely to context, prototype a cross-modal memory association engine, and build out the forgetting engine with finer-grained controls. On the platform side, expect continued performance improvements, broader system-model adaptation, and a more consistent API experience. We are also bringing repeatable single-turn replay to the trial-run window.
