Hi to all, I've just uploaded a new version of Intrusive, the intrusive container library. You can find the library in Boost.Vault/Containers: http://boost-consulting.com/vault/index.php?directory=Containers or Boost.Sandbox CVS These are the changes from the last version: -> Added ihashset and ihashmultiset hashed intrusive containers. -> Bugfixes and performance enhancements. -> Documentation has been improved. Intrusive uses new quickbook code importing feature to maintain documentation examples synchronized with the library. Tested in WinXP-Visual 7.1 and MinGW-gcc 4.1 Comments and suggestions welcome! Regards, Ion
