I can find the commit graph in bitbucket server (Stash), does the feature exists in this version?

[G__Sylvie_Davies__bit-booster_com_]

Bitbucket Server (a.k.a. Stash) has never had a built-in commit graph (see: BSERV-2534).   Some confusion arises because Bitbucket Cloud (a.k.a. bitbucket.org) has always had one.  But all is not lost. There are a number of add-ons available for Bitbucket Server through the Atlassian Marketplace that provide a commit-graph, including:

• Bit-Booster - Rebase Amend Squash (paid) - includes a graph integrated into the commits view.
• Awesome Graphs for Bitbucket Server (paid) - also integrated into the commits view.
• Commit Graph (free) - separate "all branches" graph available.
  
  

According to my analysis, Bit-Booster is the best git commit graph for Bitbucket Server.

Full disclosure: I wrote Bit-Booster.  I also submitted some patches to Commit Graph.

Which version were you using previously that had a commit graph?  I'm not aware of there haivng been a commit graph in Stash, but there are a number of plugins available that provide one.  We use Commit Graph.
