June 2026 monthly summary for keras-team/keras focusing on delivering cross-backend NASNetMobile support, bug resolution, and demonstrable business impact.

March 2026 — mandiant/capa: delivered a performance-focused upgrade to bytes-based rule matching and improved cache resilience. Implemented a length-prefix bytes index that enables O(1) candidate selection for byte features, dramatically reducing comparisons and speeding up rule matching and byte extraction on large rule sets. The index is constructed once at RuleSet initialization, eliminating per-match allocations and hot-path overhead. Added comprehensive tests for exact matches, startswith, mismatches, short-patterns, and mixed-pattern scenarios to validate correctness across edge cases. Hardened cache loading for RuleFeatureIndex by validating new dataclass fields during deserialization and triggering a rebuild when stale caches are detected, preventing runtime attribute errors. These changes collectively improve performance, scalability, and reliability while maintaining maintainable code and strong test coverage.

February 2026 (2026-02) monthly summary for mandiant/capa: Delivered robust Rich markup output with sanitization to prevent MarkupError and improved readability of verbose API details by removing dim styling in -vv output. Implemented documentation clarity and navigation improvements, including a typo fix and added links in README to usage, installation, limitations, and FAQ. These changes reduce risk from user-controlled content, improve developer UX, and strengthen onboarding and overall usability for end users.
