So... What's else exactly is New in Howler 2020?

If there is just one thing to mention, to single out:  Brushes!

But there's also so much more. Here are some recent developments as we crank through the new builds:

Here is a log of some of the internal notes shared with the beta team, through recent builds, as we go along with implementing new features, fixes and cool tools and brushes. As you may notice, a lot of focus is on brushes and new media.

Build 40 (hopefully) addresses 2 critical bugs.

Build 41 is here -  fixes the storing from the undo browser. When you're in the undo stack you can store an image from there, it should now be added as expected in the stored images stack. This is important if you want to recover a prior stored image from the history (undo) stack but have since changed the size. You can send t to stored copy, then restore it as a new image from there.

Release build 42

Release build 43

Here's a video showing it:

Build 46 - aka Howler 2020.1  (December 2019)

improved Light
            diffusion filter

Build 47 - April 2020 - read about it too: the May 2020 Newsletter #168: May-onaise

We also have a short video showing this detail:

Build 49 - (unreleased intermediate build)

It's not a big update, but it's feeling pretty good when painting on 4k.  We tried to make it faster for painting big images.

No more lag when painting on big images, for the most part, or very minor.
It was due to our realtime compression of undos. It was using 2 threads, but nowadays most entry-level PCs have quadcore or better, so we increased the number of threads. If you want to do some serious painting, you'll want some serious gear. Get off that 10-year old core 2 duo :-)

Well, we did a quick video on it. On YouTube here.

Also, there was an issue when deleting some of the default subfolders in the Medias folder. Looks like we fixed it. You might see the folder problem improved.  No more crash, we think, based on our testing. 

Build 50 - May 2020 -

Build 49 improved the compression of undo images with extra multithreading.
This build 50 improves the counterpart, namely decompression of the saved undo images. You can now scrub even faster through the undo image stack:

              preview from history stack

Build 53 - Late May 2020 - Memorial Day weekend

Miscellaneous improvements.

We've worked on the Particle Modeler somewhat.

particle modeler with sprites

We've added a collection of Sprites to the Particle Modeler of PD Howler. (not available in PD Artist - it's in the Animated filters category)
The sprites are in PNG format, you can add your own. The ones included initially are from Particle Pack 1.1 by Kenney Vleugels at  -  big thanks to Kenney and other contributors.

Video intro to the Sprites added in Particle Modeler - on YouTube:


Build 55 - Mid-June 2020

No new features, just some audio-related development we did of the rock shooting game, with added sound effects.  We haven't worked out the attribution for the various sound effects yet, so that's something we cannot ship yet.
We do maintain documentation for the API, but haven't documented the new features yet.

A new Demo version was released from build 55.

As a reminder:
We also have a playlist with a bunch of video tutorials here on YouTube:

Getting Started VBDrawing Tutorial

Plus we also have a LUA scripting interface, to make your filters, or run some Lua filters from the Gimp

Hold the Presses! we have another update!

Howler 13 is now at release build 56!

What's new in build 56? A few things, mostly internal, but one big thing" Stored Images are no longer kept in memory. They won't waste your precious RAM, so you can focus on better, larger images. PLUS, they're kept on disk in the Temp folder so if there's a power loss, a crash or other incident causing Howler to go down, your stored images won't be lost, they'll still be on disk and you can recover them when restarting Howler.

Here's a brief video intro:
