Ruby on Rails 2.3.6 发布

Ruby on Rails 刚刚发布了 2.3.6: 该版本包含六个月以来的 bug 修复，一小些新特性，以及一个到 Rails 3 的桥接。同时该版本废弃了一些无用的功能，而这些功能将于 Rails 3 中被删除。

详细的改进内容：

Upgrade Rack from 1.0.1 to 1.1.0.
XSS prevention: update to match Rails 3 and move to the official plugin at http://github.com/rails/rails_xss.
Cookies: convenient cookie jar add-ons to set permanent or signed cookies, or both at once: cookies.permanent.signed[:remember_me] = current_user.id. Read more.
Flash: promote alert and notice, the most common flash keys in many apps, to self.alert = '...' and self.notice = '...'. Add redirect_to url, :alert => '...' and :notice => '...'. Read more.
i18n: localize the label helper.

Namespacing: support optional table name prefixes on modules by defining self.table_name_prefix. Read more.
Destroy uses optimistic locking.
Counter cache: use Post.reset_counters(1234, :comments) to count the number of comments for post 1234 and reset its comments_count cache.
PostgreSQL: always use standard-conforming strings, if supported.
MySQL: add index length support. Read more.
MySQL: add_ and change_column support column positioning using :first => true and :after => :other_column.

Upgrade i18n from 1.3.3 to 1.3.7.
Upgrade TZInfo from 0.3.12 to 0.3.16.
Multibyte: speed up string verification and cleaning.
JSON: use YAJL for JSON decoding, if available. gem install yajl-ruby
Testing: add assert_blank and assert_present. Read more.
Core: backport Object#singleton_class from Ruby 1.8.8, deprecating our Object#metaclass.
Core: add Object#presence that returns the object if it’s #present? otherwise returns nil. Example: region = params[:state].presence || params[:country].presence || 'US'
Core: add Enumerable#exclude? to match include?.
Core: rename Array#rand to Array#random_element to avoid collision with Kernel#rand.
Core: rename Date# and Time#last_(month|year) to #prev_(month|year) for Ruby 1.9 forward compatibility.

JSON: set ActiveResource::Base.include_root_in_json = true to serialize as a hash of model name -> attributes instead of a bare attributes hash. Defaults to false.
