Since a few hours we're having, thanks to Edin, Windows snapshots for the upcoming PHP 5.3 release. In combination with the latest sources from CVS everybody should be able to test the current state.
There are quite a few new features already committed to the CVS tree, some of them are documented in the NEWS file and READMEs in CVS, most of them have been commented on Planet PHP so I suggest searching there for more information and keep this list short:
Namespaces: A way to help you organizing your code.
Late Static Binding: Gives you the class name used when calling a static method.
Improved ini-handling: .htaccess file like per-directory configuration and much more
__callStatic magic method: similar to __call but for static calls
mysqlnd: a replacement for libmysql for better PHP-MySQL-Integration
getopt() on any platform (inclding windows)
As you can see there's lots of stuff which needs testing! The earlier bugs are found the earlier they can be fixed! In case you ever wondered how you could give back something to PHP (which you certainly should do) you might take a look at our test coverage reports to see which areas of PHP need more testing and provide additional tests. (See qa.php.net and Marcus's slides for an introduction to test writing) Having more tests is important for us - and you don't have to know much about PHP internals to write proper tests (sometimes it's even better to write black-box tests...)
But well, there's not only PHP 5.3: If you're interested in unicode you should certainly take a look at PHP 6 and if you're running older systems you should consider upgrading to the latest 5.2 release instead of waiting for PHP 5.3 - the stable release is not expected within this year and many things there can change till it's released.
And as a final note: Test the snaps as often as you can - generic tests can never cover all use-cases and - as said above - fixing regressions is harder after a release than during development. (And be warned: We won't take any complaints from people not testing in time)
While browsing through the net I often find pages I like to share, but well, I don't want to spent time writing a blog article neither do I like putting the link without comment in this blog. Therefore I've created a small tool which helps me with publishing links to my new Link-Blog with a single click from my web browser. On that page you'll find any kind of stuff - I guess most of the content will be German.
So why did I create my own system instead of using del.icio.us or some service like that? - Well there are two reasons: a) It's my system and I have full control and b) in future I'll add some code which will automatically extract teasers from the linked page and add these to the list - like I already did for YouTube videos.
Ilia recently published the probably final release candidate of the current stable tree: PHP 5.2.4RC2. The stable release can be expected soon. This release fixes quite some bugs from older versions and does a few minor adjustments. Please test the RC release so unexpected regressions can be detected and fixed before it's marked stable. If regressions and other problems aren't detected now it will take a few months till the next version will be released, so do your best to make sure it's worth being called stable! Please file found issues, after checking for other reports and the documentation, into the bug tracker. The recent trend to report bugs using blogs isn't working well!
In other news one could read that there were also some major improvements in the development of PHP 6 made: Next to all that Unicode related work which was made over the last months PHP got, due to Andrey, mysqlnd as PHP-optimized replacement for libmysql and, thanks to Dmitry's work, namespace support. So this weekend might be the perfect time for sending you're family visting other parts of the family, letting them sweat on some beach or having fun at some theme park - then you can sit down, relax, and, after testing PHP 5.2.4RC2, give that new stuff in PHP 6 a test.
