---------------
qtbase-opensource-src (5.12.4+dfsg-4ubuntu1) eoan; urgency=medium

  * Backport two patches from upstream 5.12.5 release:
    - Use Xft DPI as basis for HiDPI scaling (LP: #1834333).
    - Fix crash when closing floating QDialogs, by reverting a breaking
      change from 5.12.4 release.
  * Update symbols files from the current build logs.
