I need a list of fixes for each recent CentOS release.
This feels like it should be simple, but I can't see a simple way to do it.
It's not hard to find the Centos release notes: https://wiki.centos.org/Manuals/ReleaseNotes
And, as an example, release notes for CentOS-7-1908 (currently the latest version of CentOS 7) are here.
Here's where my problem starts. Under Fixed Issues, it just says "For all the fixed issues it is best to look at the errata release page here and look for fixes dated starting Aug 6th 2019.", where 'here' links to: https://access.redhat.com/errata/#/
I'd prefer it if they explicitly said what they meant by 'starting'. Do they mean "starting then and going forwards" (since, inclusive) or "starting then and going backwards" (up to, inclusive)? Do they mean something else?
Given that CentOS-7(1908), AKA CentOS-7.7, was released in September, it seems reasonably clear that "starting Aug 6th", means "starting Aug 6th and going backwards".
Or perhaps they mean, to see what defects have been fixed since 7.7, look at anything with a fixed date of Aug 6th or later? That would imply that if a bug has a date of Aug 7, you can be 100% sure it wasn't fixed in this build, but a bug was fixed on Aug 5, then that bug might or might be present in 7.7.
It would be nice to know what they really mean.
Even if I assume that anything up to Aug 6 is fixed, and anything after is not, then I'm still only close to having what I want, which is to know what was fixed in 7.7 that was not fixed in 7.6.
If I could work out what's fixed in 7.6 and what's fixed in 7.7, then I could work out what's fixed in 7.7 but not fixed in 7.6. It wouldn't tell me when a defect was introduced, and it doesn't tell me anything about defects that haven't yet been fixed, but in this case, that's not important to me. YMMV.
But here are my other issues:
There's no obvious good way to download a list from the webpage. I could scrape it, but that's ugly. Am I missing something?
This is the RedHat errata page, not the CentOS errata page. I know CentOS and RedHat are more or less the same, but is it exactly the same? Comparing individual bugs between RH and CE, I can see that there's usually a couple of days before the CE bug gets fixed. Can I be sure that a RedHat build and the corresponding CentOS build both contain the same bugfixes, or is there a chance that a bug fixed close to the cutoff date might make it into one but not the other?
