When I look through this thread I think we forget two other important
feature of the 1.5 release: We started using merge tracking & changelists.

Merge tracking will give 1.4 clients+users a hard time on updates and merges
as they don't have any builtin merge support for the svn:mergeinfo property.

(See my other mail: 1.5 clients update this property on merges, copying,
etc. and merge this property automatically.. 1.4 clients can only use it as
an ordinary property)

Looking through svn_entries I found these other wc additions since 1.4.X:
- changelist
File registration on a changelist is reset

- keep_local (impacts directories only)
svn rm --keep-local dir
Won't keep directory

- working-size
svn status won't see changes when the timestamp has not changed but the file
size has.

===
All these items break if 1.4 and 1.5 clients are used on the same working
copy.
