Launcher build 656 released!

Build 656 has been released to the stable update stream.

We've added:

  • Support for custom Java JVM arguments (remember that giant box in Java Settings labelled "Java Args"? Well, now it works)
  • Support for wrapper commands (so you can use stuff like optirun in Linux)
  • Oracle Java runtimes previously had no vendor name. Now they show up prefixed with "Oracle".
  • The Java detection is now smarter on Windows and supports more vendors and locations.
  • Probably not a huge deal, but the launcher now correctly identifies arm64/aarch64 as a 64-bit platform.

Have fun!

Hello whenever I install a modpack and I get on it I press singleplayer and it just pulls me back into technic launcher and I don't know what to do.

Before I say anything, I would like to say thanks for releasing this I'm glad we have an upgrade. But I've been trying to load up vanilla Minecraft but for no reason it's says I have enough RAM but it says I need java 16 and I'm using Java 1.8.0_291 64 bit. Does anyone know a work around this problem?

same things happening to me, i legit cannot open ANY of my installed modpacks even with no mods on them

you broke something. A modpack i played before the update is now not launching. Instead i gat an error saying not able to create JVM. The Console is telling me that it could not launch because of insufficient heap size. its set to java 1.8 64-bit and there is more than enough free RAM

I took a quick look into it. The problem is gone when i delete my set of java arguments. it works when i add one random of those arguments and it completely goes mayhem when i use more than one.

can you put your explanation in dumb please

you may be able to start your mod when you go to Launcher Options then to the tab java settings and get rid of everything in the java argument section. What they did is defaulting a lot of possible java arguments so you can't play around with them anymore.
