rpm updates and longevity

[Arthur G Cannon <cannon2 us ibm com>]

Hi all, I have a couple of questions I hope you--the collective :-)--can
answer.  First, does anyone know how long fedora-legacy will release rpm
updates for bugfixes/vulnerabilities after the release of a version?  Will
it be like RedHat used to be a long time ago where they support the release
for a couple of years or will it be what it is now where once a new version
comes out all updates cease for previous versions?

thanks in advance...
