[webkit-dev] Upgrading Buildbot on EWS

[Aakash Jain]

Hi All,

I am planning to upgrade Buildbot on EWS (ews-build.webkit.org) tomorrow 
(Sunday, Oct 6th) around 6am PST from v1.7 to v1.8.2. It would give us few 
security fixes. Note that we aren't upgrading to Buildbot 2.0+ yet, since it 
need Python 3 compatibility. Python 3 compatibility work would be done 
separately.

I have already tested this version (v1.8.2) on the UAT instance 
(ews-build.webkit-uat.org). The risk is minimal and the downtime should be only 
few minutes. Please let me know if there is any concern.

Thanks
Aakash
