Changelog

This page summarises changes, updates, and new features added to Lichess over time. Check out our open source repositories for the details of every change we've ever made.

August 2026

At a glance

  • New theme options on the website - select your name/the ⚙️ icon on the top bar and then Theme to try them:
    • An all-new special light theme with a custom background image. In the Theme menu, set it to Light and toggle on Background image to try it.
    • Adjustable background image opacity for background image themes, making many parts more readable in both light and dark styles.
    • Customise how round the website is, from straight to very round edges on nearly every part of the user interface.
      New theme options - background image on light theme, opacity, and roundness
  • Major mobile app improvements:
    • Get notifications for broadcasts for tournaments and FIDE players you follow.
    • Sign in by email, which resolved common sign-in issues. If you or your friends had issues signing into the app in the past, now is the time to try it again.
    • Play against Maia offline, an engine designed to mimic human play.
    • Go even darker with the AMOLED black theme. Being pure black, it complete turns off the pixels, saving you battery life on AMOLED screens.

Technical and other changes

Technical changes

API

lila

  • Boards were moved from PNG to WebP but later pulled back for 2D to acommodate users of old Safari browsers. (added in #21304, reverted in #21413) by SergioGlorias
    • Conversion to WebP done and still retained for 3D, which notably is optional and not used in embeds (boards in #21309, pieces in #21311) by SergioGlorias
  • Remove Handset icon from various files following the removal of voice chat (#21219) by SergioGlorias
  • ui(build): automatically apply CSS prefixes based on browserslist (#21452) by Simek

  • Migrate bloom-filter (#21444) by lenguyenthanh
    • Revert “Migrate bloom-filter” (#21451) by Thibault. Per analysis in Discord: “--add-opens=java.base/java.lang=ALL-UNNAMED applies to the entire java.lang package where every classpath dependency can reflect into private details of all core classes. It would broaden the reach of a compromised dependency, allows new dependencies to form on undocumented jdk internals that may change, and creates a hidden jvm startup requirement for every deployment path. This may bee too much for a Bloom-filter optimization.”

Web
