2.4.0

I am excited to release 2.4.0 today! This version contains some critical updates of the server core to have better performances.

Better link integration

The JSON server is now only useful when you are using the LotAtc mission script API (as lotatcLink.registerAtis or lotatcLink.registerUserFlag) . If you are not utilizing this feature, you can disable it and reduce CPU impact (it is now disabled by default).

The updated link integration ensures that weather, datalink, drawing, and marks data are synchronized more effectively (better performances, avoiding potential CPU peaks in some cases). This improvement will also enable extra features in the future.

In the image above:

Enable/disable the JSON server (only with use of the LotAtc mission script)
Automatic install of LotAtc Json launcher, to use with 1.
Load automatically MIST and IA commands for Instructor, only needs to utilize with Instructor (no need to have 1. enabled)

You can also revert the DCS World/Scripts/MissionScripting.lua if you have modify it before.

Datalink rework

The datalink network management has undergone a significant overhaul. The new implementation fixes numerous bugs and provides better performance as well.

ESM/RWR evolution

RWR is the youngest feature of LotAtc, and I have enhanced the detection algorithm to provide more realistic and useful results for users.

Better simulation

Now you can set the tracking_off_delay, time for the simulation to consider a track lost if no more radar spot. Put -1 to disabled, 0 for instant lost or the time desired. Delay is in seconds.

Better performances

This version fix an important issue with LotAtc Advanced clients that causes too much network process on server impact.

It also fix some leaks on Client/Server side.

Versioning

The 2.4.0 is compatible with 2.3.x branch

I have changed the rule for maintenance version. With recent developpement, I have a more stable network protocol. Starting with the 2.3, all minor version changes (2.3, 2.4,…) will be compatible each others.
