I just put up the file released for 1.6. You'll notice that I've got all of the new methods in there, including the comment and geocoding API methods.
Just a couple of notes:
- The photos_getWithGeoData() and photos_getWithoutGeoData() functions use the same style of arguments as photos_search(). That is to say that you need to pass an associative array if you want to use any of the optional arguments.
- By default, phpFlickr will use PHP's XML parsing functions. This is different from the 1.6-beta release, but the same as every version before it. If you would like to use the SAXY parser which handles unusual characters better, but can use a lot more memory. Just bear that in mind if you are going to use it. To use the SAXY parser, use the following code (with whatever modifications you need, of course):
$f = new phpFlickr('[api key]');
$f->useSAXY(true);
