Dec 1, 2025December 2025: Focused on delivering business-value via documentation governance, security hardening, and robust dev tooling for SpacetimeDB. Key work included a naming convention for documentation pages, a fault-tolerant commitlog replay mode to improve debugging and reliability, security improvements in HTTP error handling to prevent leakage of tokens, and comprehensive replay-logic fixes that address system-table handling, sequences, and updates. These changes streamlined content maintenance, reduced security risk in logs, and strengthened production-replay safety without altering core production semantics.

Oct 1, 2025October 2025 (2025-10) Highlights: - Major architectural refactor enabling asynchronous execution and multi-instance module management for SpacetimeDB, laying the groundwork for scalable, procedure-enabled workloads across tenants. - Disk efficiency and resilience improvements via commitlog snapshotting on segment rotation, addressing bloat from many small segments. - Expanded procedures support and tooling, introducing a procedures API, macro, and scheduling infrastructure to enable side-effecting database functions. - End-to-end capability for WASM-based procedures, including HTTP/WS endpoints and initial procedure_sleep_until syscall, enabling asynchronous procedure execution within modules. - Strengthened developer experience and reproducibility with Nix-based development environment and integrated cargo-insta testing workflow. Note: No explicit major user-facing bug fixes documented this month; focus was on architectural modernization and feature enablement with additive API changes.

Feb 1, 2025February 2025 monthly summary for clockworklabs/SpacetimeDB focused on developer experience and documentation quality. Delivered a documentation update clarifying set-semantic duplicate handling for Table.insert and Table.try_insert, ensuring that inserting an exact duplicate row is a no-op even under unique constraints. This aligns user expectations with actual behavior, reduces ambiguity, and supports smoother adoption and debugging. No code changes were required this month; emphasis was on communicating correct semantics and improving DX.
