Rails - Jan 2005 - Rails 0.9.5: A world of fixes and tweaks

This release is mostly about polishing the Rails by closing holes, 
deficiencies, and subtle extensions to existing features. The 
long-awaited Directions and generator upgrade have been postponed to 
the next release. The highlights of this release is:

* *Rewritten reloading*: Working in development with models and 
controllers reloading on every request now resembles "the real thing"
a
lot more by actually removing the model classes before reloading them. 
This fixes a bunch of subtle bugs and makes it possible to remove a 
method and see it reflected without restarting the application.

* *Create and update collections:* Through calls like text_field 
"student[]", "last_name", it''s now much easier to
get input tags like
<input name="student[123][last_name]"... />, which together with
the
fact that Base#create, Base#update, Base#destroy, Base#delete, 
AssociationCollection#build, and AssociationCollection#create now all 
accept arrays enables handling of many records at once.

* *Stopping after render/redirect:* Any before_filter can now terminate 
the chain by calling render or redirect and the pattern of 
redirect-and-return now works again. The first call to either render or 
redirect wins as well and subsequent calls are ignored.

That''s just three of the 37 changes, fixes, and additions available in 
Rails 0.9.5. You can read the full story in the changelogs:

* Active Record: http://ar.rubyonrails.com/files/CHANGELOG.html
* Action Pack  : http://ap.rubyonrails.com/files/CHANGELOG.html
* Rails        : http://rails.rubyonrails.com/files/CHANGELOG.html

This release shouldn''t require any changes to your application if 
you''re coming from Rails 0.9.4 unless you were relying on const_missing
to load non-AR/AO/AC classes. In that case, you''ll have to start being 
explicit with require_dependency for the reloading to be triggered.

Does this mean that development mode will be a bit slower?
