Jun 1, 2026June 2026 monthly summary for libgdx/libgdx: Delivered a critical UI rendering fix for password fields and strengthened cross-font consistency. Major outcome: password field bullets now render with Unicode (U+2022) instead of Windows-1252 default, with documentation updates for BitmapFont usage and zero-arg constructor caveats. Impact includes improved cross-platform rendering accuracy, reduced user confusion, and clearer API guidance. Code refined under commit f9af1f6273e04da84eaffebbb782d083441634b0 (issue #7810); formatting enforced via Spotless.

May 1, 2026Month: 2026-05 — Focused on stability and correctness in core rendering paths of LibGDX. Delivered a targeted bug fix to BitmapFontCache.clear() to reset glyphCount, preventing color handling regressions when clearing and re-adding multi-color text. This change ensures correct rendering of cached multi-color text and addresses a regression (#7793), reducing rendering inconsistencies for text-heavy applications and editors that rely on BitmapFontCache. The fix aligns with existing tests and provides a clear regression path for future changes. Business value: improves user-visible text rendering reliability, reducing support tickets and rework for game developers using multi-color fonts.
