We are releasing new version 9.87 for beta testing today, and (for the next month or so) you can find it in the BETA TESTING downloads area here in our SourceForge Archives.
This new version 9.87 has had more changes than any of the prior 3 or 4 release cycles. Now it is much easier to configure LAC for use by arbitrary joystick or console game controller hardware. Two of our 54 simulated aircraft got small improvements in the mathematics of their flight model, and one of our tutorial missions was re-written and improved.
We have already published the Lac09p87.tar.gz archive containing source code ready to compile. We have also published the huge "PcLinuxOs2023LAC987.iso" file version comprising an entire. bootable LINUX operating system for industry-standard X86 hardware and containing a preconfigured, fully compiled version of LAC Version 9.87. For detailed instructions covering use of bootable "iso" images like this, take a look at the "README.txt" file we published last year for a similar .iso release. CLICK HERE to download that README.txt file.
Soon we will also publish a precompiled "AppImage" version that should work with all of the most popular LINUX distros for industry-standard x86 hardware.
Of course, you can always find a detailed summary of the changes made available from this version by accessing our online "ChangeLog" web page. CLICK HERE and scroll down to the bottom of that big long page.

If you are UPGRADING LAC to V9.87 from a prior version, you should expect to suffer from a segmentation fault unless you DELETE the "LacControls.txt" file from any prior version of LAC. Further details about this can be found in our online ChangeLog web page, in the section describing version 9.87 as referenced in the first posting of this thread. Be sure to read that information.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
LAC developers began alpha-testing new version 9.87 in late Dec2025, with a more sophisticated menu system for configuring Joysticks or Console Game Controllers. If you've updated LAC to Version 9.87 or beyond, CLICK HERE for the new instruction you'll need.

We just found a significant bug in beta-test version 9.87 that may make it impossible to increase or decrease throttles unless you are equipped with a hardware joystick or hardware console game controller equipped with hardware throttle controls. If you are using "keyboard and mouse" controls for primary flight functions, we recommend AVOIDING new beta-test version 9.87. Stick with the current production 9.83 instead, until the bug is fixed in some future version to be announced in this forum.
Further details are available in our "LAC Bug Tracking" forum here:
Update from 23Jan2026: We just found an easy workaround that can be used to prevent the bug mentioned in the prior post from troubling you. The workaround has been published, with step-by-step details, at the end of the thread referenced from our "LAC Bug Tracking" forum as discussed immediately above.
