TL;DR: The New WebApp (Modern Theme) is now the default; the old Web UI is deprecated and will be removed on November 17th.
Back in March, we rolled out the new Web UI — a big step forward for LimaCharlie. It wasn’t just a new coat of paint — we rebuilt major parts of the app to make it faster, cleaner, and easier to use. Since then, we’ve kept polishing it based on your feedback — improving layouts, fixing rough edges, and making sure everything works smoothly across all screens.
Now, after six months of running both versions side by side, we’re confident the new Web App (Modern Theme) is ready to take over.
Starting today, it’s the default experience for everyone. 
The old UI is now deprecated and will be retired on November 17.
If you’re still using it, please make the switch soon — the transition is seamless, and everything you need is already in place. If you spot anything missing, or something that still works better in the old UI, please let us know via Feature Request here — your feedback has been a huge help in shaping this release.
Thanks for being part of this evolution! We’ll keep improving the Web App to make LimaCharlie faster, smoother, and just plain nicer to use.
