--------------------------------
Assignee: Julian Foad
> multi-wc-format
> ---------------
>
> Key: SVN-4883
> URL: https://issues.apache.org/jira/browse/SVN-4883
> Project: Subversion
> Issue Type: Improvement
> Affects Versions: 1.14.0
> Reporter: Julian Foad
> Assignee: Julian Foad
> Priority: Major
>
> Allow a new version of the Subversion client to work on a WC that uses an
> older format, without upgrading that WC to the newest format the client knows.
> Concrete example (currently hypothetical):
> * if a v1.15 client were to support this feature, it could be made
> compatible with both the WC format used from Subversion 1.8 to 1.14 ("WC
> format 31") and a new format that would be introduced at the same time in
> 1.15 ("WC format 32").
> This will allow the user to:
> * use the new client and an old client against the same (old-format) WC
> * use the new client's new features with a (new-format) WC
> An implementation of this was recently merged into trunk. It was was
> developed on a branch named 'multi-wc-format'.
> UI exposure of this feature includes:
> * 'svn checkout' and 'svn upgrade' default to the oldest compatible WC
> format.
> * 'svn checkout' and 'svn upgrade' accept an option such as
> '--compatible-version=1.15' to request a newer format.
