This is an important update and I urge people to update ASAP. Several bugs had crept in the 1.500 version due to heavy refactoring.
* fix a severe bug where the proxy settings didn't always get set * fix a bug where https domains whitelists could not be turned off * work around a webkit bug where the back and forward history go to the same spot * fix bug where certificate retrieval code didn't always exhaust all possible routes to the target server * add command and search history feature * add save command and search history to disk feature * fix a bug where : commands would not always expand an alias https://opensource.conformal.com/snapshots/xxxterm/xxxterm-1.517.tgz
