You know, releasing a patch that will fix things is something you do in 5 minutes.
First you find a source of a bug in millions of lines of code.
Than you have to come up with possible solution.
Than implement the solution.
Test is to see if it works and if it didn't break something else.
Prepare the patch for release.
Release it.
I'd prefer they take their time and release patches that fix problems without causing new ones.
