I should have been more specific. The release notes tells us a bit, but the changes file at

http://svn.apache.org/repos/asf/subversion/trunk/CHANGES

has the real details I am usually interested in. Here are a few of interest:

1.6.16:
   * fix potential crash when requesting mergeinfo (r902467)
1.6.13:
   * fix mergeinfo miscalculation during 2-url merges (issue #3648)
1.6.12:
   * disable custom file mutexes on Windows (r879902, -16)
   * more improvements to 'svn merge --reintegrate' (r935631)
1.6.11:
  * mergeinfo improvements with non-inheritable mergeinfo (issue #3573)
1.6.6:
  * handle tree conflicts involving replacements (issue #3486)
1.6.2:
  * avoid potential segfault with subtree mergeinfo (r36613, -15, -31, -41)
1.6.1:
  * improve 'svn merge' performance with subtree mergeinfo (r36444)
1.6.0:
    * "tree" conflicts now handled more gracefully (issue #2282, #2908)

I really can't tell which of these were done on the client (and thus we already have) and which were done on the server. And that keeps me from being able to usefully answer questions like, "What are the top 5 or so fixes we'll get if we upgrade the server to 1.6?" We can't get a concrete sense of stability/performance improvements we'll see, or whether merges will go better, etc. Without that information, we can't prioritize an upgrade.

Note that a lot of these relate to merges. I have no idea where the split is between the server and the client as far as merges go. Does the client say, "produce some information for me to do this merge?" and let the server go off to produce it, or does the client say, "diff this and this, and search for mergeinfo here and here, etc., and send me that so I can put it together sensibly"? I realize others on this list may be able to tell where a bug fix went in just from the descriptions, but I can't, and I suspect most users not reading this list can't tell either.
