It’s been less than a week since PNGGauntlet 3 was released, and now PNGGauntlet 3.1 is out! It turns out that when I found PNGGauntlet 3, forgotten and incomplete, I hadn’t realized exactly how incomplete it was. Most everything worked, but the options dialog was only half-implemented, not allowing you to change OptiPNG and DeflOpt options. Worse, I’d broken the ability to launch PNGGauntlet with command-line options, which also broke the “Open With…” feature introduced in 2.0.1. I wanted to fix those bugs, but I know that I personally hate it when I update a program only to have another update right away. I knew I needed some neat feature to add to make it more palatable to update, and the only thing I could think of was the feature that everybody asks me for every time I release PNGGauntlet. So I did it – PNGGauntlet will now use all of your processor cores to compress files in parallel. You can turn it off if you don’t want it, but in my tests on an older dual-core machine, it halved the time to compress a batch of images. Hopefully that will make this update go down a bit smoother.
Update: OK, so it looks like there are still a few bugs, introduced by adding the parallel compression and the new compressors. Non-PNG files are being converted to PNG but keeping their original file names, and errors are popping up while parallel-compressing files. Sorry, I’ll have a 3.1.1 version out soon that addresses these. No, I didn’t “remove features” in favor of nonsensical behavior, these are all just bugs.
