An anonymous reader writes "After > 6 months of waiting, 2.4.21 is here. Lots of cleanups, and a patch which gives a MAJOR boost to the 'feel' of the system under heavy disk IO, especially on IDE systems. As usual, available from your local kernel.org mirror or ftp.COUNTRYCODE.kernel.org/pub/linux/kernel/v2.4/! Tidbit: 'Current bandwidth utilization 131.72 Mbit/s '." See the Changelog for new stuff.
