PHP Upgrading Worthwhile ... or not? PHP5.2.3 >> PHP5.2.17

From the following sp开发者_开发技巧ecific viewpoints, is it necessary to upgrade from 5.2.3 >> 5.2.17 or not?

Some more background info that may help with my specificness of this question:

What I DO care about/need best improvements:

• GD image manipulation
• Speed of Load

What I DONT need improvements in:

• site security
• Database usage/SQL etc

Check out the PHP Changelog here.

At first glance I don't find speed improvements between 5.2.3 and 5.2.17, but there are a few bug fixes regarding specific GDLib functions which might affect the things you're coding.

I'd recommend to upgrade to 5.3 anyway because of the other issues you don't need improvement in! ;-)

5.2 is EOL already. Consider upgrading to 5.3.6 now.
