Feather Client Patch

Feather got acquired and its launcher started turning itself into “Dawn”. This keeps an existing install as Feather, and switches the ads off while it's in there.

[01] why

No off switch, so I made one

Feather Client was acquired, and its launcher began replacing itself with a new client called Dawn. If you liked Feather the way it was, there was no setting to stop it.

[02] what it changes

The patch

  • blocksthe auto-update to Dawn
  • removesthe ad bar and ad panel
  • enablesDevTools (Ctrl+Shift+I)
  • turns offthe asar integrity check, so the patched launcher loads

[03] careful by design

It tries hard not to break anything

  • Every edit is the same length and made in place, in files you already have. Nothing is downloaded.
  • No admin rights needed.
  • Safe to run twice. It spots what's already patched.
  • If it doesn't recognise your Feather version, it stops without touching anything.
  • It backs up the originals first, so undoing it is two file renames.

[04] already on dawn?

There might be a way back

Feather's updater sometimes leaves the old Feather installer behind in %LOCALAPPDATA%\feather-updater. Reinstall from that, run the patch before opening the launcher, and you're back.

[05] the trade-off

What it costs you

Updates are off on purpose, because that's what stops Dawn. The price is that Feather stays on its current Minecraft version.
