March 2026 performance highlights for KittyCAD/modeling-app: Implemented cross-platform system certificate management and TLS configuration, introduced a dedicated module for certificate handling, and removed Windows-specific code to ensure consistent TLS behavior across macOS and Windows. Reworked the core-dump workflow to submit support tickets instead of uploading debug information, enabling smoother issue triage and faster user support. Removed telemetry from the Language Server Protocol to enhance user privacy and reduce data transmission overhead. Additionally, stabilized certificate tests to reduce flakiness, improving CI reliability.

January 2026: Implemented security hardening and reliable lifecycle handling in KittyCAD/modeling-app. Delivered per-host dynamic CSP for sign-in and staging, introduced new utilities for host-based folder naming and CSP generation, and integrated CSP across components. Added graceful backend shutdown handling with new state transitions and context properties to ensure clean shutdowns on backend requests. Fixed staging CSP to align with production security baseline and prepared groundwork for consistent security posture across environments. These changes reduce security risk, improve maintainability, and enhance system resilience.
