RHEL Versions and differences
Can anyone tell me the dates of release and significant differences between releases of RHEL?
I'm due to do the RHCE course soon (version 6).
Couple of books on amazon ranging in price from £2 for the 2000 edition, £5 for the 2002 edition, to £25 for the latest edition (Albeit still version 5).
Am I wasting money getting an older version of the book?
