sourcetree windows 3.0.8 pull calls api.bitbucket.org with TLS 1.0 (BB will force 1.2 on dec-1st)

Hi Atlassian Sourcetree Community.

I saw this link stating that bitbucket will turn off tls 1.0 and 1.1, and only use tls 1.2 starting december-1.  https://bitbucket.org/blog/deprecating-tlsv1-tlsv1-1-2018-12-01

So I upgraded sourcetree to the latest windows version, 3.0.8, and did a wireshark/tcpdump network capture.  Most items are good tls 1.2, but when doing a Pull I do see some bad tls 1.0 entries.  I'm on windows 10 pro ver 1703.  Doing git from sourcetree Open->Terminal looks good ( GIT_CURL_VERBOSE=1 git ls-remote https://bitbucket.org/ uses 1.2).  I'm using the built-in git of sourcetree.

So i'm concerned that something will break on that date.  Can someone else confirm or deny what I saw, that some part of sourcetree is still using old tls 1.0 ?

Thanks.  -Mike

Can you check what version of Git/Git Credential Manager you are using? see https://githubengineering.com/crypto-removal-notice/ for more information.

Sourcetree relies on the OS and should be just using TLS 1.2
