New in Fission 2.5:
* Fission now has full compatibility with MacOS 10.15 (Catalina).
* Fission now offers full Dark Mode support, with a “Match System” option that uses the Dark theme when your Mac is in Dark Mode, and the Light theme when in Light Mode. You can also still select your desired theme manually, right in Fission's Preferences window.
* Several major improvements have been made to Fission's waveform drawing. In addition, the Dark theme once again correctly draws and highlights the waveform, restoring full functionality.
* A new wizard has been added to Fission, which includes a new “Quick Tour” to provide a helpful overview of the application, as well as update notes on the first launch of a new version.
