Well, just a week or two after 2.9 is release, wordpress is at it again. 2.9.1 is here and we are all having to update again. If you were wondering what minute and trivial processes were addressed in 2.9.1, here they are:
What was changed in 2.9.1
- Update-core.php small validation fix
- Rotate counter-clockwise tooltip in “Edit Media” is spelt incorrectly
- Lack of escaping in _wp_comment_row()
- curl_setopt() In Feed Options?
- Some buttons have gone square in 2.9
- sanitize_user_object() throws fatal error on user property objects
- Fatal error: Call to undefined method WP_Error::__destruct()
- Plugin Compatibility Fails to Consider Future RC Versions
- sanitize_text_field() issue with UTF-8 characters
- Rotate image buttons don’t show up on PHP installs without imagerotate()
- Warning: Cannot modify header information… in class-json.php
- Increase download timeout
- timezone reset
- Code editor bug in Safari
- parts of metadata API fail on user metadata
- update-core.php doesn’t remove the upgrade files if the upgrade fails due to too old of a PHP or MySQL version
- Upgrades Fail Because of [11883]
- warning on line 790 of wp-includes/rewrite.php
- upgrade.php dies hard on MySQL < 4.1.0
- could not be converted to UTF-8 / WordPress should cache failed feed fetches so as to avoid overloading feed sources
- cron stopped working with standard configuration
- ‘$wpdb’ typo in wp-admin/maint/repair.php causing table prefix not to appear
- Upload Handling. Use is_numeric instead of ctype_digit.
- Need confirmation/undo/something for media delete
What does this mean? Let’s break it down…
Update-core.php small validation fix
What was this change? It was a W3C change. Something wasn’t validating right in the update-core.php file. It was a paragraph tag, (<p>) that wasn’t closing properly. On line 162, they removed an extra space and added the (</p>) to the end of the line. Now w3c is happy. Yay…
Rotate counter-clockwise tooltip in “Edit Media” is spelt incorrectly
Just as the title says, someone spelled something wrong. image-edit.php on line 44, they spelled it “Rotate couter-clockwise” instead of “Rotate counter-clockwise”. Fixed. Whoopee…

Lack of escaping in _wp_comment_row()
This one is a good one. Lack of escaping basically means it is vulnerable to possible hacks and attacks. And through the templating system as well. Good on ya, wordpress. This one is worth it.
curl_setopt() In Feed Options?
First of all, it is never a good sign when they themselves put a question mark in their own title. Basically Curl, (you don’t need to know what that is) wasn’t working correctly within some versions of PHP. PHP itself addressed this issue: http://bugs.php.net/bug.php?id=49531. They disabled some CURL options and moved on. Smart move on their part…
Some buttons have gone square in 2.9
This one is great!! I love this one. No joke, they addressed the fact that some buttons are not as ROUND as they once were. The video shows where some of them are located. If you still have 2.9, try to find them yourself…
