SLADE v3.1.10 Released
Thu, Feb 20 2020

UPDATE 20th Feb: 3.1.10 is up which fixes some major issues in 3.1.9.

The first SLADE release of 2020 is here, v3.1.9 3.1.10. This is most likely going to be the last release of 3.1.x unless any particularly nasty bugs show up.

Here's what is changed since 3.1.8:

Resource Editor

  • Name sorting in the entry list is now case-insensitive
  • Don't show entry delete confirmation prompt if no entry is selected

Text Editor

  • Improved comment handling, issues with block comments should hopefully now be fixed
  • Added an option to disable the up/down arrow keys for switching between function definitions in tooltips
  • Fixed a crash when opening a text entry with no language selected


  • Enabled more standard lua libraries for use in scripts (all except io and os)

Map Editor

  • Recalculate slopes when a thing's z-height is changed in 3d mode
  • Added some extra map editor menu items that were previously keybind-only
  • Added GL sector specials to ZDoom configurations (thanks @Talon1024)

Last but not least, I finally have a macos build up again for this version. Unfortunately the version of wxWidgets used to build it is still old, so all the weird dark theme / opengl bugs are still there, but at least there's an update.

SLADE v3.1.8 Released
Fri, Nov 22 2019

Time for another minor bugfix release - 3.1.8 (at this rate we really will get to 3.1.10 before 3.2.0 is ready :P). The full list of changes is below:


  • Fixed 'use timidity' setting reverting when opening the preferences dialog


  • Updated to wxWidgets 3.1.3, which should fix some text editor highlighting issues
  • FreeImage is now statically linked, so FreeImage.dll is no longer required

Resource Editor

  • Fixed entries sometimes being misidentified as 'Doom Gfx (Snea)' or 'SRB2 Encore'
  • Fixed conversion to Hexen Planar gfx format
  • Fixed 'Replace in Maps' feature not working correctly when run multiple times
  • Fixed display of very long paths above the entry list

Map Editor

  • Field of view is now configurable
v3.1.7 was Released
Wed, Oct 30 2019

A bit late due to issues with the website around the time it was released, but anyway, 3.1.7 is (was) released!

It's mostly to fix the text editor issues with 3.1.6 on Windows. The changes are below:


  • Updated the SRB2 palette and added support for SRB2 encore lumps (thanks @SteelTitanium)
  • Converting graphics to png format is now done in-memory rather than via a temp file


  • Reverted to wxWidgets v3.1.1 for Windows builds, which should fix issues with the text editor crashing on autocomplete and not showing calltips
  • If the Doom Builder 2 installation directory is not found, SLADE will now prompt to browse for the (GZ)DB2 executable manually

Text Editor

  • Show the number of occurrences replaced after clicking 'Replace All'

Map Editor

  • Vertex slope things are now displayed at absolute height instead of relative to the sector floor
v3.1.6 now with More Bits (tm)
Thu, Aug 22 2019

SLADE v3.1.6 is now available for download, including a few changes to Windows builds - it should no longer require the MSVC runtimes to be installed separately, and there is now an 'experimental' 64bit build available.

The 64bit build currently doesn't support MIDI playback via fluidsynth (you'll have to set up and use timidity instead for now). Otherwise, the 64bit build should run a bit faster on modern hardware and allow opening much larger files than the 32bit version can.

Apart from that, this release is mostly a minor bugfix release, including a fix for the long-standing issue where playing most ogg files would cause a crash. See the full list of changes below:


  • Zip files with the .pk4 extension can now be opened
  • Various minor crash and bug fixes

Resource Editor

  • Fixed a crash when playing certain ogg audio entries
  • Fixed a crash when viewing certain font (eg. DBIGFONT) entries (thanks @mykola-ambar)
  • Fixed misaligned next/prev image buttons for multi-image graphics entries (thanks @mykola-ambar)

Map Editor

  • Fixed BEHAVIOR/SCRIPTS entries sometimes being created with blank names (thanks @Talon1024)

UPDATE 5-Sep-2019: A macOS build of 3.1.6 is (finally) available over at the downloads page.

SLADE v3.1.5 and Linux Flatpak
Tue, May 07 2019

A new release of SLADE is up, with a bunch of fixes and minor improvements:


  • Simplified temp directory handling, should now hopefully always be accessible (if not, the program won't run)
  • Added kpf extension for zip archives
  • Fixed issues opening zip/pk3 files where the path has non-ASCII characters
  • HTTPS links in the start page should now correctly open in an external browser
  • Fix various crashes


  • Fixed ZScript default properties parsing (eg. +SPAWNCEILING should now work)
  • Fixed a crash when a ZScript file #included itself or introduced a circular #include chain
  • Updated ZScript and SRB2 lua language definitions (thanks @SteelTitanium)

Resource Editor

  • Renaming a folder to change case only (eg. DECORATE -> Decorate) should now correctly mark it as modified
  • Always show path and 'up' button for archives that support folders
  • Fixed issues when editing a PNAMES entry via the data entry editor
  • Fixed archive format check for entry types (this was preventing eg. Wolf3D graphics from being detected correctly)
  • Improved detection of pod archives to avoid false positives

Texture Editor

  • Fixed an issue where renaming the currently open texture via the texture list would not update the name text box in the editor

Text Editor

  • Fixed an issue where non-commented text could stay in the 'comment' colour after closing a block comment

As per usual it can be downloaded from the downloads page.

Also, linux users may notice another link added to the downloads page - SLADE now has an official flatpak release for linux, which should make installing and keeping it up to date much simpler.
