There was a bug in 0.6.2
The orange Piwik message shows “Piwik 1 is available” message: Users affected are running PHP 5.2.0 (and above) with either safe_mode enabled or open_basedir set, and using the curl extension.
You can patch your existing Piwik installation manually since the “one-click” update would fail in this case. We recommend that affected 0.6.2 users replace piwik/core/Http.php with the new version [/url] at [url=http://dev.piwik.org/trac/export/2258/trunk/core/Http.php]http://dev.piwik.org/trac/export/2258/trunk/core/Http.php.
Note: You may have to wait up to 8 hrs for the cached version number to update.
