This update is all about safely testing out a major new version of the software. The developers packed both the old, reliable version and a new, upgraded version into a single download. This matters to the developers so they can slowly roll out the new version without risking breaking things for everyone at once, but it's designed to be completely invisible to you.
What's new
- A combined package: Instead of just getting the old app or the new app, your download now includes both. A tiny "loader" program acts like a traffic cop, deciding which version to open for you.
- A staged rollout: The developers are slowly letting people try the new version, starting with just 1% of users. This percentage will grow over time until everyone is using the new version.
Improvements
- Invisible safety net: If the new version fails to load for any reason, the app automatically falls back to the old version in the same window. You don't have to do anything to fix it.
- Shared settings: Your settings, passwords, and preferences are shared between both versions. If your computer switches from the old version to the new one, you won't lose any of your setup.
- No mid-session surprises: The app will only switch versions if you close and reopen a window. It will never switch while you're actively working.
Fixes
- No specific bugs were fixed in this release; it is focused entirely on the rollout setup.
