v0.24.0

All Platforms:

• Fixed a recording with no audio at all: on machines using the software
  recording path, two parts of the pipeline could collide and leave the
  recording silent.
• A failed recording no longer breaks the next one: if a recording session
  died unexpectedly it could leave a stuck background process holding the file,
  and every later recording would fail until it was cleared by hand. That can no
  longer happen, and a session that does die is cleaned up automatically.
• Interrupted recordings are kept, not lost: a recording cut short by a
  crash is recovered alongside your other captures instead of being discarded.
• Recordings start faster: the encoder was being detected twice at the start
  of every recording, once needlessly.
• More natural voice levels: the automatic gain now leaves more room above
  your speaking level, so louder syllables keep their punch instead of being
  flattened against the ceiling. Your level meter will read a little lower than
  before, which is the extra headroom.
• Video editor settings: the Preview Editor settings page has a new Video
  Editor section, so save-on-copy, close-on-copy and copy-on-delete can differ
  between images and videos instead of sharing one set.
• Small region selections work: dragging a very thin selection produced
  nothing at all, with no error. Fixed.
• Crop button now reads "Apply Crop".

Diagnostics:

• Debug logging: Settings → Health → Debug has an opt-in "Enable Debug
  Logging" switch, off by default, with a button that opens the log folder. When
  something goes wrong, the log names it, which makes a bug report a single file
  instead of a conversation.

Linux:

• Folder buttons open the file manager: buttons that open a folder did
  nothing at all. Fixed.

macOS:

• Failures explain themselves: a capture that could not complete used to
  close with nothing and no message. It now says what happened and, where the
  fix is known, how to fix it.
• Screen Recording permission: if the permission is missing or has been
  invalidated (which macOS often does after a system update), the app now says
  so and gives the steps to restore it.
• Permissions are clearer: Accessibility is now labelled Recommended rather
  than Optional, explains what it is used for, and can be skipped without being
  asked again on every launch.
• Manage Permissions has been added to the menu bar item, so the permissions
  window can be reopened whenever you want.
• Stuck captures clean themselves up: a capture that never manages to open
  now exits on its own instead of lingering as an invisible process.

Windows:

• Nothing new this release.

Known issues:

• On Windows 10, the shaded overlay shown when selecting a capture area renders
  solid black instead of see-through, and frosted-glass window effects do not
  apply. Windows 11 is unaffected. Still under investigation.

Note: Windows 10 is not officially supported, but effort is being made to
ensure rudimentary compatibility at this time.
