Just thought you ought to know.
In the commercial versions of BitKeeper, the latest released version was sent along with the lease from our license server. With the open-source release, the code has to actually poll our download area on bitkeeper.org to find the latest release.
This is done in upgrade.c:upgrade_latestVersion() and is done as a background process that is spawned at most once a day and writes the results to $HOME/.bk/latest-bkver. As a result, sometimes the data can be stale, and even running ‘bk version’ twice in a row and return 2 different answers as the first one will start a refresh and only the second call will new the new answer.
In this particular case, I know the author of this email often runs his machines completely firewalled off from the Internet so the background refreshes will fail and the data becomes stale.
BTW if a new version is available then:
sudo bk upgrade
is usually at that is needed to install that version on the current machine. It downloads the current installer image and uses it to upgrade the bk that is only your PATH.
