# 3.1.0 (unreleased)

## Overview ##

## Upgrading

 * `Object::has_extension()` and `Object::add_extension()` deprecated in favour of using late static binding, please use `{class}::has_extension()` and `{class}::add_extension()` instead, where {class} is the class name of your DataObject class.
 * Removed `SiteTree.MetaTitle` and `SiteTree.MetaKeywords` since they are irrelevant in terms of SEO ([1](http://www.seomoz.org/learn-seo/title-tag), [2](http://www.mattcutts.com/blog/keywords-meta-tag-in-web-search/)) and general page informancy
 * Deprecated `Profiler` class, use third-party solutions like [xhprof](https://github.com/facebook/xhprof/)
 * Removed defunct or unnecessary debug GET parameters: 
   `debug_profile`, `debug_memory`, `profile_trace`, `debug_javascript`, `debug_behaviour`
 * Removed `Member_ProfileForm`, use `CMSProfileController` instead
 * `SiteTree::$nested_urls` enabled by default. To disable, call `SiteTree::disable_nested_urls()`.
 * Removed CMS permission checks from `File->canEdit()` and `File->canDelete()`. If you have unsecured controllers relying on these permissions, please override them through a `DataExtension`.
API Deprecated Profiler class, removed related debug GET params Use third party tools like XHProf instead. Removed defunct or unnecessary debug GET parameters: debug_profile, debug_memory, profile_trace, debug_javascript, debug_behaviour 2012-07-05 11:39:59 +02:00			`# 3.1.0 (unreleased)`

CMS member profile now is no longer in a popup (#7880) 2012-10-08 04:02:01 +02:00			`debug_profile`, `debug_memory`, `profile_trace`, `debug_javascript`, `debug_behaviour`
NEW Enable SiteTree::$nested_urls by default 2012-10-08 17:01:53 +02:00			* Removed `Member_ProfileForm`, use `CMSProfileController` instead
API File->canEdit() returns TRUE by default (not checking CMS perms) This is a measure to support form fields and controllers interacting with files in different contexts, for example an UploadField used in a ModelAdmin, or a website frontend. The check for 'CMS_ACCESS_AssetAdmin' was too restricting. This wasn't a problem in 2.x simply because the old FileField/Upload classes didn't respect File->can*() permissions. 2012-10-12 15:37:07 +02:00			* `SiteTree::$nested_urls` enabled by default. To disable, call `SiteTree::disable_nested_urls()`.
