Please don’t get confused about the versions we provide. The version numbers following this syntax:
Year[YY]Month[MM]Day[DD] of the release. So Version 211206 means the version was released on the 6th of December in 2021.

You may not need the newest version. You are fine as long as your version is doing what you want. If there are important updates, they will be announced in the google group. Usually, the new versions contain all that we have posted in the LAStools google group since the last release. It is wise to be a member and read the mails posted there. To see the changes of a new version, you may look at the CHANGES.txt file within the ZIP file of the delivery.

The licensed version always contain also the current version of the OpenSource parts.
It is optional to download or update the OpenSource part separately.

If you are not sure which version you are using:
In Windows, just execute one of the executables like “lasdatum.exe.” The GUI will show the version number at the bottom left. On a command line, type the executable name followed by -h: This will output the help of the program and will usually also show the version number:

> lasdatum -h
