## Description

This unofficial plugin provides fixes for selected WordPress bugs, so you don’t 
have to wait for the next WordPress core release. **This does not mean you can stop
updating WordPress!** It just means that you’ll get a few selected fixes more quickly.

Recent fixes:

 * **WordPress 6.9**
    - Set sender as blank to workaround Sendmail issue when sendmail_from and -f
      are both used, see [WP#64368](https://core.trac.wordpress.org/ticket/64368).

Fixes are specific to your version of WordPress. It may be that your version of 
WordPress has no fixes. That’s fine. Keep the plugin activated and updated, in case
you need it for a subsequent version of WordPress!

### Complete Hotfix List

 * **WordPress 6.9**
    - Works around issue where Sendmail fails due to `sendmail_from` and `-f` both
      being used.
 * **WordPress 3.5**
    - Lets you update Twenty Twelve if it is shown as “broken” after installing 
      3.5
    - Lets you update WordPress and install or update plugins and themes. (Only 
      some Windows servers running IIS were affected.) You’ll need to [install this plugin manually](https://codex.wordpress.org/Managing_Plugins#Manual_Plugin_Installation).
 * **WordPress 3.4.2**
    - Fix adding and updating Custom Fields
 * **WordPress 3.3**
    - Prevent plugin and theme styles from bleeding into the dashboard
    - Work around a bug for people without built-in JSON support
 * **WordPress 3.2**
    - Include JSON support for people with funky PHP setups
 * **WordPress 3.1.3**
    - Fix a bug that caused `post_status` to malfunction if passed an array
 * **WordPress 3.1**
    - Fix a bug that caused some taxonomy query manipulations (like excluding categories)
      to not work like they did before.
 * **WordPress 3.0.5**
    - Prevent KSES from overzealously stripping images and other advanced HTML from
      Administrator/Editor comments on display.

## Installation

 1. [Click here](http://coveredwebservices.com/wp-plugin-install/?plugin=hotfix) to
    install and activate.
 2. Done! Just remember to keep the plugin up to date!

Or, you can do [a manual installation using FTP](https://codex.wordpress.org/Managing_Plugins#Manual_Plugin_Installation),
which may be necessary on certain Windows servers running IIS (WordPress 3.5 only).

## FAQ

### How do I know which hotfixes are being applied to my version?

Read the “Complete Hotfix List” section in the description. A later version of the
plugin may list the hotfixes in a special WordPress admin page.
