May 2026 monthly summary for swift-nav/libsbp focusing on delivering a high-value, backwards-compatible extension to the SBP orientation data model and strengthening test/CI coverage.

In March 2026, hardening the JSON streaming decoder in swift-nav/libsbp to improve reliability when consuming block-buffered input. Implemented an internal buffering strategy by replacing a boolean end-of-file flag with an Option<usize> to track incomplete buffer length, enabling unlimited retries for incomplete parses while preserving end-of-stream detection. Adjusted buffer advancement so it only occurs on successful parses to avoid data loss. Added 4 unit tests and validated against a block-buffered pipeline (test scenario using grep with gstdbuf); verified reduction of decode errors from 799 to 0. No public API changes. Jira AP-1080. Commit: 9c1cbccbb9a3d6722cc7f447f0d3da838f006c94.

June 2025: Delivered documentation and consistency improvements for DF389 fields across C, Haskell, and Java; refreshed Docker image tag references and clarified encoding of standard deviation values; aligned documentation across HOWTO.md and README.md.

February 2025 — swift-nav/rules_swiftnav: Delivered CI Sanitizer Symbolizer Integration to surface UBSAN/MSAN/TSAN symbol data in CI failures, enabling faster debugging and more reliable CI runs. No major bugs fixed this month. Business value: shorter triage cycles, more robust CI, and improved developer productivity. Technologies/skills: CI tooling, sanitizer symbolizers, UBSAN/MSAN/TSAN, Git-based release workflow.

December 2024 monthly summary for swift-nav/rules_swiftnav: Implemented a targeted bug fix to Clang-Tidy flag filtering in _safe_flags within clang_tidy.bzl. Removed an unnecessary condition that checked for flags containing '-std=', preserving only genuinely unsupported flags in the filter. This change was committed as 2deb089e3717d78d42a78e543e3f0449f72f11a6 with message 'Remove unnecessary condition in _safe_flags function (#132)'. The update reduces CI noise from false positives and improves the maintainability of the clang-tidy configuration, contributing to more reliable code analysis downstream.
