Sorry, I'm so used to building out of SVN that I've forgotten how
feature-different SVN is from the release. Indeed, changeParams is not
in any released version of OpenLayers, only in subversion. The
/dev/lib/OpenLayers.js will always be a subversion version of
OpenLayers, but it is a multi-file, rather than single-file, version.

Schuyler and I have been lamenting the lack of a new release for a
couple weeks now, and I think that this email is evidence that we need
to move more seriously on this. In the meantime, you can use the
/dev/lib/OpenLayers.js file, and we will send an announcement to the
list when we do so so that you have a non-development version to use.
Alternatively, in the meantime, you can build your own single file
version, which I recommend if your site is going to be used for anything
other than testing -- the non-single file version does need to load a
lot of files in order to work, so it does take a noticably long time to
get started the first time you visit the page.

Sorry for the inconvenience, and we'll work on getting a new release out
ASAP.
