Paint.net 4.3 released with performance improvements and switch to .NET 5

A new version of the open source image editor Paint.net was released this week. The latest version, Paint.Net 4.3, is the first that uses the .NET 5 framework and no longer .NET Framework 4.8. The framework change has positive and negative consequences for the application.

Paint.net 4.3 is already available. Users who have installed the application and enabled automatic update checks should receive the update notification and an option to download and install the new version on the next start of the program. Paint.net 4.3 offline and portable versions are available on GitHub, and there is a Microsoft Store version, but it is updated automatically as well.

Portable zips are new and may be downloaded from GitHub. These won’t update automatically, however.

Performance improved significantly according to the developer of Paint.net. Part of it comes from the switch from the .NET Framework 4.8 to .NET 5.

.NET 5 is a massive update to the .NET runtime, and brings a lot in terms of performance with its improved code generation (JIT). It also enables me to optimize code even further via the use of SIMD intrinsics (SSE* and AVX* on x86/x64, and AdvSIMD on ARM64), which I’ve started putting to good use. In addition, effects are faster, plugin loading is faster (especially for shapes), the Magic Wand and Paint Bucket tools are significantly faster, and overall performance is just plain better. Even installation and updating are faster because I was able to remove the “Optimizing performance” stage from setup.

The official release notes list more than a dozen areas with performance improvements, but that is not the only change. ARM64 devices are natively supported by Paint.Net 4.3, and that means that performance on devices such as the Surface Pro X has improved as a consequence.

Speaking of consequences, the migration to .NET 5 caused some plugins to no longer work with that version. The developer managed to get most of the plugins working again, but there is a chance that some plugins won’t work anymore with the new version.

The developer plans to migrate to .NET 6 in the near future; the final release is expected in November, and a Paint.NET update will be released shortly thereafter according to the developer.

Xbox Insiders app displays a rating to indicate how games will perform on your computer

Can you run it? Gamers may recognize the phrase, it is the tag line of a popular benchmarking service that determines whether your computer can run a game or not. It’s actually a pretty terrible way to judge the performance of your system, but things like these have a cult/meme status. Now, if you are curious whether your PC can handle a game, there is a way you can get an idea. The Xbox app now displays a rating to indicate how the games will perform on your computer. I tried this on a Windows 10 machine with the regular Xbox app, it does not have the rating system. You will need to be using the Xbox Insiders app on your system to get the new feature. The Xbox app has been getting new features steadily, Microsoft recently added an option in the app that allows you to install games to any folder.

Latest Ventoy includes VentoyPlugson, a GUI configuration tool

Image
Ventoy 1.0.62, the latest version of the popular open source tool to create bootable USB devices using disk images such as ISO, includes a new tool called VentoyPlugson. VentoyPlugson gives Ventoy users a graphical user interface to configure the tool. Up until now, Ventoy users could only configure the application through the ventoy.json file directly; this option is not going away, and users can even mix and match both options, e.g. by using VentoyPlugson to create a ventoy.json file and then editing the file manually to tweak it further, The latest release version of Ventoy includes the tool in the zip archive. Windows users need to extract the archive that they download from the official repository and run VentoyPlugson.exe afterwards. ADVERTISEMENT It displays a small GUI. Select the Ventoy USB device and then the Start button; this should open the configuration page in the default browser. If that does not work, use the Link button instead. There is also a refresh button i

Progressive Web Apps for Firefox Extension

Image
Progressive Web Apps for Firefox is a browser extension for Mozilla’s Firefox web browser and a command line utility to install, manage and use Progressive Web Apps (PWAs) in Firefox. Mozilla’s Firefox web browser supports many of the APIs that PWAs use, but Mozilla decided some time ago to remove installation options from Firefox. Most Chromium-based browsers support installing PWAs directly from within. Installation on desktop systems adds these applications to the Start Menu for quick access, and these apps launch in their own dedicated window. Progressive Web Apps for Firefox introduces a number of features to Firefox that users of the browser may find useful. Some functionality may even be useful to users who don’t use PWAs. ADVERTISEMENT PWAs that are installed in Firefox through the extension benefit from a number of extra features. One of the most interesting features of the extension is that PWAs are run in an isolated Firefox extension that may use multiple profiles to s
