What's new in 1.8.91

1.8.91 fixes a crash when opening the theme picker in the packaged app and updates a vulnerable cryptography dependency.

Fixed

  • Opening the theme picker and switching themes or accents no longer crashes the installed or portable app (#452).
  • The bug report window uses the family text field and scrollbars, with grain clipped to the cards and a transparent scrollbar corner.

Security

  • Updated System.Security.Cryptography.Pkcs to 9.0.21 for GHSA-846f-f764-76mx and GHSA-2fmv-rv2c-59x7.
