@andfoy, I merged split-plugins last night, so you can start working in your assigned tasks now.

[ccordoba12]

We decided with @andfoy that some LSP features will be implemented for beta2 and the rest in beta3.

hi all. In current master, I fail to make code completion working on the left editor screen. Is it normal ?

[ccordoba12]

Yes, it is. We need to fix some things for Windows yet.

[stonebig]

Isn't it working now on Windows ? I just tried with laster master and it looks ok. maybe just luck ?

[ccordoba12]

It should be fixed now after PR #8600.
