Hello everybody!\n\nInfernals is almost here, so today were looking at the preliminary release notes for the Stellaris 4.2.0 Corvus update.\n\nThe 4.2 update is named after the Corvus constellation, representing the crow. In Greek mythology it was the sacred bird of the god Apollo, and was known for its beautiful white feathers. In one myth, Apollo ordered the crow to watch over his lover Coronis - who fell in love with a mortal man, Ischys. When the crow reported back to Apollo, he scorched the birds feathers black in a fit of rage.\n\nNext week youll be able to scorch the galaxy:\n

4.2.0 Performance Open Beta

Last Friday we put an Open Beta up on the [c]stellaris_test[/c] branch that contains some behind the scenes changes to how modifiers are applied and how threading works. These modifier node and thread pool changes are from newer versions of our engine, and this branch contains the basic groundwork for the improvements planned for 4.3.0 and that Open Beta that we expect to start a few weeks from now.\n\nThe data so far has been positive, so currently were expecting to roll it into the actual 4.2.0 release. Join us on the branch if you have time and help us break it.

Features

• New modifier node system

  [/*]

• New thread pool system

Balance

• The Summon Dimensional Fleet Astral Action now summons Astral Cruisers and Astral Escorts equal to twice the number of Rifts you have explored.

Livestream

Davide and I are planning on continuing burninating the galaxy while being distracted by answering questions in our last Infernals livestream. Will we make it to the end of Galactic Hyperthermia and set the universe on fire? Depends on how many questions you ask.
