Wesnoth 1.19.26

[Pentarctagon]

Wesnoth 1.19.26 is out!

Get on itch.io

Get on Steam

This new release in the 1.19.x development series sees various changes and improvements in various areas.

As this is a development version, we would like to remind everyone how the testing and feedback process works for these:

• If you download Wesnoth stand-alone, make sure to keep the latest stable release around in case the game breaks and you find yourself unable to get your daily fix of Wesnoth.
• Playtest the game, and make sure to report any bugs you find! Even obvious bugs can be left unfixed if everyone assumes someone else has already reported it.
• For any bugs found, or to request new features to be added, check out bug tracker here. First though, please read our instructions for reporting bugs on the wiki, which will give your bug report or feature request the best chance of being addressed.
• Near the end of the release notes below you will find a list of the most important bugs known at the time of the release. Some items are due to be fixed in future releases of the 1.19.x series, but for others we depend on contributed patches from volunteer coders like you!

General

Changes To Existing Content»

• Unit footprints
  Unit footprints have been reworked to now more strongly show multi-turn movement. It is now also possible to set custom footprints for a unit.

Miscellaneous improvements»

• [move_units_fake]
  The [move_units_fake] tag now supports units moving in parallel rather than sequentially.
• SIMD
  Performance of various pixel-level operations has been improved through using SIMD functions. This can be disabled in the advanced preferences if it causes any issues.

Important changes since 1.18.x

⁂

The multiplayer and add-ons servers for this development series are up and running. Because development versions are a moving target, the development multiplayer server only accepts the latest version in the series. Add-ons may break due to changes to the WML and Lua APIs throughout development series — any problems involving them should be reported to the respective add-on maintainers.

If you find any bugs, do not hesitate to report them, but please read the instructions on how to report bugs first! As bug reports in the forums tend to be forgotten, you will get better results using our bug tracker. We require your help for finding and fixing issues, no matter how obvious, trivial, or complicated they seem!

Have fun!

SIMD
Performance of various pixel-level operations has been improved through using SIMD functions. This can be disabled in the advanced preferences if it causes any issues.

Does that mean Wesnoth will crash on PCs without SSE2 by default?

This is the related commit I believe:
https://github.com/wesnoth/wesnoth/comm ... 8b2b0770e0

I'm far from being an expert, but I cannot see any code that checks the actual hardware capability.

[Pentarctagon]

CPUs that old likely wouldn't be able to run Wesnoth in the first place, but there's an option to turn it off.

"Does that mean Wesnoth will crash on PCs without SSE2 by default?" -- there is a detection system that should skip the simd operations and go back to the old code if SSE2 is not detected. We haven't yet tested it on such a system though.

[mentos987]

This part is the related check:

#if defined(__SSE2__) || \
defined(_M_X64) || \
(defined(_MSC_VER) && defined(_M_IX86_FP) && _M_IX86_FP >= 2)

Yeah my bad, for some reason I thought it was AVX2 and not SSE2
In case of AVX2 that would be a real issue.

This part is the related check:

#if defined(__SSE2__) || \
defined(_M_X64) || \
(defined(_MSC_VER) && defined(_M_IX86_FP) && _M_IX86_FP >= 2)

This code checks for the machine's capability during compilation, not runtime.
But as Pentarctagon has said, this isn't likely to affect anyone, since SSE2 was introduced eons ago. Even my ~2012 netbook with Intel Atom supports it.

So today we have 12-08-2026 and yesterday was released Wesnoth v1.19.26 which when we check the site below:

https://wiki.wesnoth.org/1.19_Roadmap

should be released 19-07-2026 so should we expect that next versions of the Wesnoth will be later (like atleast 20 days later) than its in Wesnoth versions road map?

[mentos987]

I think SSE2 comes default for Win 64. And Wesnoth requires 64 bit Win these days

Nope.

Missing from the changelog: SP RNG mode is now stored in a preference, and it defaults to Reduced RNG by default.
