- Support for MacOS 12 (Monterey): Fission now has initial compatibility with the forthcoming MacOS 12 (Monterey)
- Enhancements to Fission's Built-In Updating: Fission's updating code has been overhauled and improved. It is now based on Sparkle 1.26.0, with several customizations.

- Finally, the new “Skip for Now” button allows you to delay updating if desired
- As always, we strongly recommend leaving the “Automatically check for updates” option enabled.
- Fission's manual is now provided online, rather than being built in to the application. The application's “Help” menu has also been modified and streamlined, to get you assistance as quickly as possible.
- Fission's Start window has been made more intelligent. The Cmd-0 shortcut will now open the window if its closed, close it if it's open and in the foreground, or pull it forward if it's already open but in the background

- When Fission is unlocked by entering a valid license key, in addition to displaying an animation, it will now play a brief celebratory sound for visually impaired users
- The Quick Tour now properly supports the new “Speak items under the pointer” setting in MacOS 11 (Big Sur)
- Improvements have been made for the Quick Tour to present better on small resolutions, using scrollbars to make all content accessible
- Due to breaking changes in their API, the “Share to SoundCloud” integration has been removed from Fission
- It's now possible to access several relevant menu items while the initial Quick Tour is open
- The “Purchase” button in the License window now uses a better link to get to the Buy page
- The Update window's width has been tweaked, to handle longer titles
- Get Access to Test Builds: Fission now features a new “Check for test releases” hidden preference. When active, you may receive notice of pre-release versions of the software, ahead of its wide release. If you're interested to test updates, you can turn this option on in the Debugging window (accessible by holding option while viewing the “Help” menu, then selecting “Quit and Relaunch for Debugging”).
- Fission Is Now Available Exclusively via RogueAmoeba.com: As of version 2.7.1, Fission is distributed exclusively via direct download and purchase from our site. It has been removed from the Mac App Store. See this page for more details.

Many debugging improvements have been made:
