[Buildbot-devel] [ANN] Buildbot-0.7.10

[Marcus Lindblom]

Hi,

It was changed (in reponse to another ticket) since a full clone is 
expensive to do over and over again. Rather, we just do 'hg init' if we 
need to (inital setup + error recovery and maybe branch shifts), then 
'hg pull' from thereon, to make things leaner and speedier.

I suppose the first checkout could be a 'hg clone' instead, followed by 
the same 'hg pull' as now.

Cheers,
/Marcus
