Version 1.21.6 adds three main improvements: a fix for file syncing failures on Windows, faster loading times for large projects, and better error messages when plugins conflict.

If you're running version 1.21.5 or earlier, this update addresses problems that have caused the most support requests over the past month. The file syncing issue affected users who work across multiple devices, the performance lag hit anyone managing projects over 500 MB, and the plugin conflicts were causing crashes without telling you why.

You don't need to do anything to get this version — most installations update automatically within 24 hours. If you want to update right now, you can check manually in your settings menu under "About" and select "Check for Updates."

Key Takeaways

  • Version 1.21.6 fixes a Windows file syncing bug that prevented changes from uploading to cloud storage.
  • Large projects now load 30 to 40 percent faster than they did in 1.21.5, especially on the first open after restart.
  • When two plugins try to use the same function, you now see a clear message naming both plugins instead of a generic crash error.
  • The update arrives automatically, but you can trigger it manually from your settings menu if you want it sooner.

The File Syncing Fix for Windows Users

Windows users reported that files saved locally weren't uploading to cloud storage, even though the sync status showed "complete." The problem happened most often when you had the project open on two devices at the same time, or when you switched between offline and online mode quickly.

Version 1.21.6 rewrites how the sync engine handles file locks on Windows. It now waits for the file to be fully written to disk before marking it ready to upload, which prevents the incomplete-file-upload loop that was causing the stall. If you've been holding off on updating because of this issue, this version should resolve it.

After you update, your next sync cycle will push any files that got stuck. You don't need to manually re-upload anything — the system will catch them on its own.

Performance Improvements for Large Projects

Projects larger than 500 MB were taking 15 to 30 seconds to load in version 1.21.5. Version 1.21.6 changes how the program indexes your files when it starts, loading only the metadata it needs right away instead of scanning every file in the background.

The speed gain is most noticeable the first time you open a project after restarting the program. Subsequent opens are faster too, but the first load is where you'll see the biggest difference — typically 30 to 40 percent quicker. If your projects are under 200 MB, you probably won't notice much change.

Better Error Messages When Plugins Conflict

When two plugins tried to control the same function, the program would crash with a generic error code. You had no way to know which plugins were fighting, so troubleshooting meant disabling them one at a time until the crash stopped.

Version 1.21.6 detects plugin conflicts before they crash the program and shows you a message that names both plugins and which function they're both trying to use. You can then disable one of them or check if either developer has released a newer version that plays better with others.

How to Update to Version 1.21.6

Most users will receive this version automatically within 24 hours. The program checks for updates when you start it, and if a new version is available, it downloads in the background and installs the next time you close and reopen the program.

If you want to update right now instead of waiting, open the program and go to the menu at the top left. Select "Settings," then scroll down to "About." You'll see your current version number and a button that says "Check for Updates." Click it, and if 1.21.6 is available, you'll be prompted to download and install.

The update takes about two minutes on most systems. You'll need to close the program while it installs, and you won't lose any of your work or settings — everything stays exactly as it was.

What You Don't Need to Do

You don't need to uninstall the old version first. You don't need to back up your projects before updating — the installer protects your data. You don't need to change any settings after the update finishes. When you open the program again, it will work the same way it did before, just with these three fixes in place.

If you're on a Mac or Linux, this version includes the same three fixes. The file syncing issue was Windows-only, but the performance improvements and plugin error messages apply to all systems.

Frequently Asked Questions

Will this update change how my projects look or work?

No. Version 1.21.6 fixes bugs and improves speed, but it doesn't change the interface, add new features, or alter how you save or organize your work. Everything will look and feel the same when you open it.

What if I'm still running version 1.20 or older?

You'll still receive this update automatically. The program updates from any previous version to the latest one. If you've been skipping updates, the next time you start the program it will check and download 1.21.6.

Do I need to update right away, or can I wait?

You can wait if you want. This isn't a security update, so there's no urgent reason to install it today. But if you've been experiencing file sync problems, slow loading, or plugin crashes, updating sooner will solve those problems faster.

What happens to my settings and saved work?

Everything stays. Your settings, projects, recent files, and preferences all remain exactly as they are. The update only replaces the program files, not your data.

Can I go back to version 1.21.5 if I don't like 1.21.6?

You can, but it's not straightforward — you'd need to uninstall and reinstall the older version manually. Most users who update find the improvements worth keeping. If you run into a problem after updating, contact support with details about what's happening.
