I publish today the 2.3.0 release. The 2.3.x is a large rework of the code and new important features:

Here are the main features of the 2.3.0 :

  • Datalink simulation
  • Start of ESM (RWR feature)
  • DCS Marks and IP support
  • Vulkan support
  • New generator engine
  • Better network protocol (to ensure compatibility in future version)
  • And lot more….

You can see the replay of my Twitch stream presenting the new features in the first beta:

LotAtc 2.2.x will no more received updates, I will still provide it in the next months to let users migrate to the new 2.3.x branch, users are encouraged to switch to LotAtc 2.3.x. See how to install section below.

Papi’s charts are also been updated. Thanks Papi !

If you need Papi’s charts to use them in cockpit, see there.

Next ?

The next steps are:

  • Maintenance of 2.3.0 of course :)
  • Updating documentation for 2.3.0, I am working on a complete rewrite of the documentation, I hope to provide a first version in the next weeks
  • Datalink/ESM features/enhancement (both the view and the core)
  • ATC rework (the big step of this year)
  • LotAtc Server scheduler reworking (core part but very important), this will allow better performances on servers with massive spawn/despawn units during the mission, PAR view with better refresh update
  • Others subjects that will come later…

How to install

You can install 2.3.x branch by launching the LotAtc updater then Add/remove components to add 2.3.x in parallel than 2.2.x.

The 2.3.x is not compatible with 2.2.x branch, network protocol has changed so you need that Client AND Server has same version 2.2.x or 2.3.x. You can install both versions in parallel !!! See the next video to know how to do !

This version is compatible with the 2.3.0-beta2 in both way (client/server).


All changes since 2.2.9 (2.3.0 + beta versions):
