vendor/gems/mislav-will_paginate-2.3.7/CHANGELOG.rdoc

@@ -0,0 +1,110 @@
+== 2.3.6, released 2008-10-26
+
+* Rails 2.2 fix: stop using `extract_attribute_names_from_match` inernal AR method, it no longer exists
+
+== 2.3.5, released 2008-10-07
+
+* update the backported named_scope implementation for Rails versions older than 2.1
+* break out of scope of paginated_each() yielded block when used on named scopes
+* fix paginate(:from)
+
+== 2.3.4, released 2008-09-16
+
+* Removed gem dependency to Active Support (causes trouble with vendored rails).
+* Rails 2.1: fix a failing test and a deprecation warning.
+* Cope with scoped :select when counting.
+
+== 2.3.3, released 2008-08-29
+
+* Ensure that paginate_by_sql doesn't change the original SQL query.
+* RDoc love (now live at http://mislav.caboo.se/static/will_paginate/doc/)
+* Rename :prev_label to :previous_label for consistency. old name still functions but is deprecated
+* ActiveRecord 2.1: Remove :include option from count_all query when it's possible.
+
+== 2.3.2, released 2008-05-16
+
+* Fixed LinkRenderer#stringified_merge by removing "return" from iterator block
+* Ensure that 'href' values in pagination links are escaped URLs
+
+== 2.3.1, released 2008-05-04
+
+* Fixed page numbers not showing with custom routes and implicit first page
+* Try to use Hanna for documentation (falls back to default RDoc template if not)
+
+== 2.3.0, released 2008-04-29
+
+* Changed LinkRenderer to receive collection, options and reference to view template NOT in
+  constructor, but with the #prepare method. This is a step towards supporting passing of
+  LinkRenderer (or subclass) instances that may be preconfigured in some way
+* LinkRenderer now has #page_link and #page_span methods for easier customization of output in
+  subclasses
+* Changed page_entries_info() method to adjust its output according to humanized class name of
+  collection items. Override this with :entry_name parameter (singular).
+
+    page_entries_info(@posts)
+    #-> "Displaying all 12 posts"
+    page_entries_info(@posts, :entry_name => 'item')
+    #-> "Displaying all 12 items"
+
+== 2.2.3, released 2008-04-26
+
+* will_paginate gem is no longer published on RubyForge, but on
+  gems.github.com:
+
+    gem sources -a http://gems.github.com/  (you only need to do this once)
+    gem install mislav-will_paginate
+
+* extract reusable pagination testing stuff into WillPaginate::View
+* rethink the page URL construction mechanizm to be more bulletproof when
+  combined with custom routing for page parameter
+* test that anchor parameter can be used in pagination links
+
+== 2.2.2, released 2008-04-21
+
+* Add support for page parameter in custom routes like "/foo/page/2"
+* Change output of "page_entries_info" on single-page collection and erraneous
+  output with empty collection as reported by Tim Chater
+
+== 2.2.1, released 2008-04-08
+
+* take less risky path when monkeypatching named_scope; fix that it no longer
+  requires ActiveRecord::VERSION
+* use strings in "respond_to?" calls to work around a bug in acts_as_ferret
+  stable (ugh)
+* add rake release task
+
+
+== 2.2.0, released 2008-04-07
+
+=== API changes
+* Rename WillPaginate::Collection#page_count to "total_pages" for consistency.
+  If you implemented this interface, change your implementation accordingly.
+* Remove old, deprecated style of calling Array#paginate as "paginate(page,
+  per_page)". If you want to specify :page, :per_page or :total_entries, use a
+  parameter hash.
+* Rename LinkRenderer#url_options to "url_for" and drastically optimize it
+
+=== View changes
+* Added "prev_page" and "next_page" CSS classes on previous/next page buttons
+* Add examples of pagination links styling in "examples/index.html"
+* Change gap in pagination links from "..." to
+  "<span class="gap">&hellip;</span>".
+* Add "paginated_section", a block helper that renders pagination both above and
+  below content in the block
+* Add rel="prev|next|start" to page links
+
+=== Other
+
+* Add ability to opt-in for Rails 2.1 feature "named_scope" by calling
+  WillPaginate.enable_named_scope (tested in Rails 1.2.6 and 2.0.2)
+* Support complex page parameters like "developers[page]"
+* Move Array#paginate definition to will_paginate/array.rb. You can now easily
+  use pagination on arrays outside of Rails:
+
+    gem 'will_paginate'
+    require 'will_paginate/array'
+
+* Add "paginated_each" method for iterating through every record by loading only
+  one page of records at the time
+* Rails 2: Rescue from WillPaginate::InvalidPage error with 404 Not Found by
+  default
