TL;DR: mdr v2.1.0 ("Fernandel") brings significant performance modernization under .NET 10, a brand-new automated test suite, an autonomous end-to-end WinGet release and tracking pipeline, and hardened security scanning.
Following the jump to NativeAOT in 2.0, this release modernizes the rendering engine under the hood: code block syntax highlighters now utilize compile-time [GeneratedRegex] source generators, theme palettes leverage immutable FrozenDictionary lookups, and the document ingestion pipeline streams lines with pooled buffers for zero-allocation reading. A comprehensive 27-test suite now validates formatting, markdown parsing, and terminal keybindings on every pull request.
On the release engineering front, our distribution automation has been completely rebuilt to match wtop. Building a release now generates signed, provenance-attested NativeAOT binaries across all major platforms, logs a proactive Microsoft Defender (WDSI) verification issue, and delegates upstream package publishing to an autonomous tracker that monitors Azure Pipeline validations on microsoft/winget-pkgs until the PR is merged.
This release is named in honor of legendary French actor and comedian Fernandel, celebrated worldwide for the Don Camillo series.
Key Highlights
- Modernized Rendering Engine: Switched to compile-time regex source generators ([GeneratedRegex]), immutable FrozenDictionary palettes, canonical language ID cache keys, and pooled line streaming.
- Unit Test Suite: Added 27 automated tests covering table formatting, blockquotes, syntax highlighting, and theme cycling.
- Autonomous WinGet & Release Pipeline: Synchronized distribution workflows with wtop—featuring automated upstream PR management, live Azure status tracking, and proactive Defender false-positive staging.
- Enhanced Security: Integrated automated Snyk code analysis and open-source vulnerability scanning into the CI gate.
