April 2025 — Stabilized core data workflows, improved determinism in caching and data transfer, and delivered targeted performance and reliability improvements across Tangram. Key features delivered include deterministic caching enabled by restoring setting file times to the epoch for cache entries; export body compression; import request compression; download robustness improvements with raw-byte checksums and decompression; and data integrity enhancements via storing actual vs. expected checksums in processes. Major bugs fixed include PostgreSQL indexing and index streaming issues (including index message publishing and stream config), bad SQL and FDB empty object handling, API surface simplification by removing the status field from finish arg, removal of debug remnants, test determinism improvements for snapshots, and several lifecycle/IO fixes (process stdio ordering, exit code propagation, and pipe/PTY lifecycle). Cross-cutting improvements include Linux build compatibility, code formatting cleanup, and refactors such as index subscription simplification, window-size renamed to size, and messenger trait refinements. Overall impact: increased reliability, deterministic caching, safer data transfer, improved developer productivity, and clearer error reporting across runtimes; business value includes more predictable deployments, faster iteration, and reduced production incidents.

March 2025 highlights a reliability and performance uplift across Tangram with an emphasis on faster workflows, stronger data integrity, and improved observability. Key features delivered include broad maintenance and housekeeping (dependency updates, warning cleanup, and snapshot refreshes), significant performance enhancements (faster export, improved touch-time handling, and synchronous cache operations), and several architectural/infra improvements (pipes, PTYs, and mounts support; separate index database; server diagnostics and update checks; Tangram CLI versioning). A comprehensive set of bug fixes addressed JSON deserialization, blob creation with path, finish-log handling, index metadata, large object store behavior with FoundationDB, internal error formatting, and cache hygiene. These changes reduce operational risk, boost throughput, and provide clearer release traceability.

February 2025 focused on reliability, performance, and scalable workflow enhancements across tangram. Key features and fixes include renaming internal targets for clarity and enabling unsandboxed processes; per-backend graph object insertion at end of checkin; race-based build optimization by comparing local and remote builds; restoration of tg exec and scaffold tg run with a new checkout progress indicator; and config-driven remotes plus enhanced import/export progress, enabled by Tower-based client/server for scalable operations. These changes improved build throughput, robustness of process management, and developer experience, while maintaining data integrity and operational observability. Supporting fixes included client request timeouts and environment correctness for tg.build, as well as various database-, foundationdb-, and CLI-related reliability improvements.
