Announcing the Butterfly 2.4.2 release!

Merry Christmas to everyone celebrating! 🎄

As a special gift, I am releasing Butterfly 2.4.2 today. This release is a culmination of all the nightly builds and release candidates from the past month, bringing you a stable and polished experience.

2.4 will be kept as a long-term stable version to make it as bug-free as possible. The next feature release (2.5) will take a bit longer while we focus on quality and stability.

This update will be available soon on the Play Store, Snap Store, F-Droid, and Microsoft Store. Please report any issues on GitHub and share the app to help the project grow!

We also reached 1,600 stars on GitHub—thank you for your support!

To read all the changes, please visit the nightly version blog entries here:

Performance optimizations

The app has been optimized for slower devices, usage will be faster without consuming too much memory.

Memory usage: Improved memory usage when closing documents.
Rendering: Faster pen tool, rendering, and tool switching.
Eraser: Improved performance of the eraser and path eraser tools.
WebDAV: WebDAV operations and bake queue have been optimized.

RTL layout fixes

Previously, the RTL layout for right to left languages had many issues. All known issues have been fixed, with additional improvements.

Fixed appbar layout and menu opening.
Fixed icon display issues.
Fixed text direction in label and color toolbars.

The RTL layout wont change the ordering of the toolbars, allowing anyone to easily switch languages, without worrying about re-adapting their muscle memory.

UI improvements

There are more UX improvements, including:

Add Menu: Bigger buttons for easier interaction.
PDF Export: Improved dialog layout and image export preview.
Navigation Rail: It is now thinner and takes up less space.
Feedback: Progress bars are shown when exporting, and a processing indicator has been added.
Ruler: Added a center dot for better precision.
Palette: You can now restore the current palette.
File Association: Added .tbfly file association on Windows and iOS.

Improved SVG Export Compatibility

The SVG export compatibility has been improved by using fill-opacity and stroke-opacity attributes. This change enhances the compatibility of exported SVG files with various applications and web browsers.

Bug fixes

The main focus of this release is to fix the issues that weren’t previously.

Images: Fixed issues where images would refuse to load or update (showing a gray square).
Export: Fixed invisible layers being ignored on export and PDF export crashes when changing quality.
Input: Fixed stylus buttons not working on some devices and improved line shape hit calculation.
Navigation: Fixed smooth navigation issues.
Files: Fixed renaming, duplicating, and moving files on native platforms.

Indonesian translations

I have added support for Indonesian translation. Thanks to the translators for helping me make this app available for a broader audience.

What comes next?

This release was a simple patch fixing multiple issues, the next version, 2.5, will bring new features!

But…

This app is being developed by only one person, all of these feature take time and effort.

Please consider helping me by contributing to Butterfly.

You don’t need to be a programmer to help, translating the app, improving the docs, and reporting bugs are all means of contribution that don’t require programming skills.
