Feb 1, 2026February 2026 | clockworklabs/SpacetimeDB: Focused on delivering cross-language bindings, docs, and stability improvements to accelerate adoption and reduce developer friction. Key features delivered include adding C++ Bindings, extensive C++ docs across 1/4–4/4, and a C++ smoketest for quickstart-chat, plus breaking-change readiness with an include-private flag and dependency pinning for reproducible builds. Major bugs fixed include Unreal Blackholio Tutorial rename-related issues and follow-up quickstart fixes to ensure reliability. Overall impact: strengthened multi-language support, improved developer onboarding and build reliability, and safer upgrade paths. Technologies/skills demonstrated: C++, Unreal, documentation discipline, automated testing, breaking-change planning, and version pinning.

Jan 1, 2026Month: 2026-01 — ClockworkLabs/SPACETIME DB: Focused on strengthening Unreal-based messaging reliability and enabling structured error handling across C++ and Blueprint. Key changes include a fix for fragmented message handling by switching from OnRawMessage to OnBinaryMessage (aligning with C# behavior and improving BytesRemaining reporting), and the introduction of a new Unreal Result type with codegen for new structs, tests, and a serialization macro. These efforts improve live messaging reliability, error visibility, and cross-language consistency, supporting faster debugging and safer deployments.
