[ITK-users] [ITK-dev] [ANN] ITK 4.9 Release Candidate 1 is ready for testing!

[Simon Alexander]

Hi Matt,

Quick update:  I've found two compiler bugs so far - not great.   On
hopefully better news, I've also found that update 1 has shipped.  So I
will configure that and run it against your RC2 to see if these things are
resolved.  If not I have workarounds, unsure of the wisdom of adding them.
