v10.3.0 Summary

Community-driven release with 54 pull requests from 6 contributors.

Key Themes

Security & enhancements: Implemented Content Security Policy (CSP) headers management, improved font-weight for bold elements in the default theme, and fixed a scheduler drift.
Stability & bug fixes: Resolved issues with Persona Bar language flags, CDV cache busting, config scripts, CSP header separators, and module build assembly inclusion.
Maintenance & updates: Bumped numerous dependencies including dotnet-sdk, Mimekit, BouncyCastle, Cake.Frosting, MSBuild Community Tasks, and multiple npm packages.
Developer experience: Major investment in CI/CD automation via GitHub Actions — added artifact attestation, NuGet deployment, OSSF scorecard, dependency review, pinned workflow permissions, and numerous build/release automation improvements.

Overall

This release combines meaningful security additions — most notably CSP header management — with a broad set of stability fixes and a significant overhaul of the CI/CD pipeline. While not a feature-heavy release, it lays important groundwork for developer experience and long-term maintainability.
