How to track kernel releases and changelog?
 

I want to track 2.6.33 kernel releases. I can see that kernel.org has couple of releases like rc1, rc2,rc3, git<>. Kernel 2.6.33. got released early Feb this year.
So How many releases of kernel 2.6.33 were there? I checked at kernel.org but couldnt find the complete information.

It would be great if someone can help with this.

It's in ../pub/linux/kernel.

Changelogs and downloads for all 2.6 kernels:
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/

RC's are under "../testing":
ftp://ftp.kernel.org/pub/linux/kerne...sting/v2.6.33/

There is only ever one release of kernel level - there may be an indeterminate number of release candidates.
There is a README file in the top level of the kernel source tree - start with that. It will refer you to ../Documentation/applying-patches.txt - read that as well. Then you'll have a pretty good understanding of the build/release strategy.
A good synopsis of each released kernel can be found at kernelnewbies.org (base releases only, not -rc).
