by Nick Hilliard 17 Aug '12

17 Aug '12

irrtoolset 5.0.1 has been released and is available in the usual place: ftp://ftp.isc.org/isc/IRRToolSet/ This is a bugfix release. There are no new features. The following bugs were fixed: * don't barf on pingable: and ping-hdl: attributes (RFC 5943). * don't barf on inet6num: assignment-size (RIPE policy proposal 2010-06). * RFC 5952 requires that ipv6 addresses be presented in lower case. * ipv6 addresses are now printed in optimised format. * added geoloc: and language: fields to both inetnum: and inet6num: objects. * compilation fixes for g++ 4.7 / debian wheeze. * stop talking asdot to IRRDBs. none of the IRRs supports asdot since ~2010. * silence a bunch of warnings for clang 3.0. * fix AS output for rpslcheck. Supported production targets for irrtoolset 5.0 include recent versions of: Debian / Ubuntu FreeBSD Solaris Mac OS/X The code will run on both 32 bit and 64 bit platforms. Please report any bugs to irrtoolset(a)lists.isc.org. Nick
