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：
Action Pack
- 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.
Active Record
- 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.
Active Support
- 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.

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.
Active Resource
- 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.
Action Mailer
- Upgrade TMail from 1.2.3 to 1.2.7.
Railties
- Silence RubyGems 1.3.6 deprecation warnings.
