7 Commits • 3 Features
Feb 1, 2026February 2026 - UNIkeEN/SJMCL: Focused on delivering a productive developer experience and a streamlined build. Key deliverables include an initial SJMCL VSCode extension with Tauri-based command jump and locale-key hover-to-definition, UX cleanup replacing the contributors page with an external link and updating resource authors icon, and a maintenance release with framework/build optimizations (Next.js 15.5.12, tsconfig exclude tools directory) and version bump to 0.8.2. No major bugs reported this month; engineering effort improved discoverability, UX consistency, and build performance. Technologies demonstrated: VSCode extension tooling, Tauri integration, Next.js/TypeScript configurations, and maintainability-focused refactors. Business value: faster onboarding for contributors, reduced build times, and up-to-date dependencies.

Nov 1, 2025Month 2025-11: Key platform and quality improvements for UNIkeEN/SJMCL. Features delivered include Release 0.6.x enhancements with Rust 1.91 compatibility and release bumps (0.6.0–0.6.2), plus UI polish for the skin modal and profile warnings. Major fixes cover corrected bottom padding of the view skin modal, improved 'no Minecraft profile found' warning, and macOS Mojang permissions handling. Cross-OS work includes UNIX-like permissions utilities and macOS entitlements for CI signing. Code quality gains come from refactoring for readability, addressing clippy warnings, and restructuring instance summary creation. A stability safeguard was implemented by reverting an unstable instance deletion performance optimization to preserve reliability. Overall, these efforts improve platform stability, cross-OS compatibility, and maintainability, delivering smoother upgrades and a stronger foundation for future releases.
