Release Notes: 'make profile' was updated. On glibc2 systems you can now kill -USR1 the process to get a current profile dump and restart profiling. Kline/akill/zline matching has been revamped, which should help greatly with lag under heavy user loads with many klines/akills/zlines. Denial of sending .zip files and . files (with a null extension), to prevent the spreading of exploits, was added.
