Lyrenne v2.10.3
You can now see in the app when an update is waiting.
Until now the only heads up was a tray notification about ten seconds after launch. It disappears on its own, so if you weren't looking at that exact moment you never knew there was a new version.
There's now a small pill in the top right corner when an update is available. Click it and it takes you to Settings where you can install it. It sticks around until you actually update, and it shows download progress if you start one and go back to browsing.
It only shows up if you have "Check for updates at startup" turned on. If you turned that off, nothing changes for you.
Upgrading
Auto update handles it, or grab the zip below and extract over your existing folder.
