There are no known major reorganizations required to update svnbook to cover Subversion 1.8. C. Michael Pilato plans to take the following multi-step approach to the task:
The Subversion project's release notes are generally pretty good at pointing out subtle (and major) behavior changes. Check these for stuff missed elsewhere, and file appropriately milestones issues for changes that need to be made.
Review outstanding issues marked for closure in this version.
Use the ./tools/bin/spew-svn-command-options tool in the svnbook source tree to print (with lexigraphical sorting) the subcommands and options offered by the Subversion tool chain. Doing this against the current release of Subversion and the previous allows a simple 'diff' of the output to reveal new subcommands and options. (Of course, first make sure that this script itself is up-to-date with the latest list of binaries.)
