It’s been well over 1 year since our last release. Many things have happened for all of us and even though we are still performing post-release tasks and fixing unforeseen bugs, we have persevered to get this version with over 600+ individual tasks. Thus we are releasing Pencil2D v0.6.5 into the wild!

Pencil2D Release 0.6.5, 28 days later

…Well actually make that 49 gasp. Truth be told the new version has been out since July 31st 2020. While we were working on a new release strategy the release version became more and more ambitious, however most of our team had a reality check with both their personal and professional lives so we had to decide that it was time to release a new, albeit impefect, version to update your experience.

The lack of a timely announcement was a byproduct of our desire that all officially supported platforms, including those with external maintainers were ready before the announcement, however this wasn’t possible. We also wanted to provide a bit more explanation on how the new features are meant to be used, so we produced a few video overviews to help with this.

Right now we’re furiously addressing new bugs that have appeared due to the newest features, and finally putting to rest other problems that were chasing users for years. We kindly ask everyone to please follow closely the bug tracker, as we will be also looking to release a new bug fix version, 0.6.6 by the end of september / start of october to address some of the most critical Known issues you’ll find right off the bat.

Lastly, during this past year we’ve been also dealing with additional issues introduced by traditional operating systems after a new wave of security updates. Due to this the open-source community, as well as Pencil2D users, have been reporting various issues related to file permissions. If you’d like to know what we’ve done to ease this problem and what you can do, read on!

Before you dive into the current release notes or the new feature highligths we have a surprise for everyone!

Pencil2D User Showcase Reel 2020

Back in May we made a call for content in order to update our User Showcase for 2020. Suffice to say we are overjoyed with the work that was sent and we’re proud of this community. While we couldn’t accomodate everyone, we did our best so each contributing artist would be featured and we edited the video artistically to higlight their own work. We hope you enjoy it!

Release Highlights

We also took some time to provide quick video guides to each of the new major features that have landed in Pencil2D. While humble, these will certainly improve over time with your feedback and support. Enjoy!

Windows & MacOS Permissions Issues

Begining 2019 we started to have many reports about crashes and corrupted files (something we had managed to minimize with previous patches), after many months of investigation and support tickets, we narrowed down the root cause of these problems. It was the Operating Systems themselves.

Windows 10 and macOS Mojave, and later Catalina have been on a crusade to enhance their security protocols. While this is not a bad thing to do, when most software vendors require thorough scrutiny of all files to even let the end user system work, this quickly becomes a breeding ground for chaos.

Attempting to spare you from the technical details, put quite simply, Pencil2D was forced into this security mayhem and to be honest we still haven’t found a suitable solution that can be bundled with the software.

With the recent Windows OS signed certification and macOS notarization buffs, we’ve found ourselves fighting for survival, so to speak.

To ease our affected users experience we have made and found a set of guides on how to deal with permissions & security lock-in for our software.

Known issues & Gotchas

Here is a non-exhaustive list of bugs that we are already aware of, but were unable to fix in this release. Rest assured, we will do our best to fix all of them eventually.

  • #1417 Panels spilling their content or timeline getting pushed outside the scree when the vertical screen size is too narrow, usually on 1366x768 laptops (this was partially addressed by #1369 already)
  • #1426 Onion skins, layers & documents show “ghosted” (buffered) images after creating a selection
  • #1427 Crash when importing the same layer multiple times with the new Pencil2D project layer import feature
  • #1428 Crash when creating new file after using peg-bar alignment
  • #1429 Undoing a stroke made in an empty frame, relative to an existing keyframe will create a new keyframe instead and mess up the undo order.
  • #1433 & #1435 Polyline tool drawing not updating properly while drawing on vector & bitmap layers respectively.

  • Zooming out the camera layer to less than 25% will increase the chance of Crashing Pencil2D
  • #748, #1004, #1098 Misc undo/redo issues. New Undo / Redo system under development will be reviewed for v0.7.0
  • #1117 The CLI (Command-Line Interface) export operation consumes more memory than using the editor
  • #1120 Undoing Selection Flip X / Y will delete the drawing instead. A possible fix will be available for the new undo system.
  • #1133 Lag and buggy strokes with Huion tablets. Workaround: disabling the “linear optimizer” in your tablet driver may help if that option is available, see this post
  • #1179 Currently there’s an audio delay of 1-2 frames for in-editor playback & exported files. However on some systems the opposite happens where the audio delay on playback might be longer by 12-16 or more frames, but on export it works ok.
  • #1189 Zoom shortcut on drawing tools not working properly with the Middle Mouse Button (Win) and mouse input in general (All Operating Systems)
  • #1193 The feather slider widget (Brush Tool) has a higher max value than the input value, and any value above 96 pixels will not allow you to paint.
  • #1196 A unerasable stroke appears when drawing if you turn off the pressure sensitivity checkbox with drawing tools.
  • #943 Color Palette (Bitmap): Some issues when replacing the first swatch remain. Only thumbnail changes color, but the actual color doesn’t. It is recommended you make a new item rather than changing it.
  • #1055 Color Palette (Bitmap): Swatches will not update using the Replace command. It only works when having a vector layer active. (Note: Create your custom palettes with a vector layer selected or import them from GIMP or Krita using *.gpl files)

  • Undo: Undoing moving a keyframe to a new frame will create a blank keyframe on the place where it used to be.
  • Undo, Smudge Tool (Bitmap): You cannot UNDO the smudge tool at the moment.
  • Blur Tool (Bitmap): Pressing ALT with smudge tool doesn’t work, do NOT use it. Use other drawing apps for smudge or blur effects for now.
  • Fill Tool (Vector): Filling a stroke requires the stroke to be selected.
  • Fill Tool (Vector): “Stroke thickness” option will reset pressure sensitive lines width.
  • Vector Engine is a WIP and does not work as intended. Much more work will be required, please avoid using it for production.

How can I help?

In case you missed our announcement on social media, now you can upload your Pencil2D project here to help Pencil2D development.

With a project library, our dev team will be able to test new features and detect bugs more effectively. We are still looking for more projects from our users so please consider sharing them with us if you have any. The projects are invaluable to us even if you just share them privately.

To those who have already shared your work with us, we are very grateful for your help. Some of the fixes in this very release would not have been possible without you.

Pencil2D is developed by passionate volunteers in their spare time. You can become one too, there are many ways to help other than programming! Please visit Contribute Page for further information.
