Releases for Hierarchical Select

This will be the final RC for HS 3!

Changes since DRUPAL-5--3-0-RC6:

Changes since DRUPAL-5--3-0-RC4:

• Developer mode was accidentally still enabled.
• Fixed #317658: In-line 'create new item' dialog displayed in the wrong level
• Fixed #317425: Bug in Token support of HS Taxonomy

Changes since DRUPAL-5--3-0-RC2:

Changes since DRUPAL-5--3-0-BETA2:

Yes, finally, the first HS 3 beta!

✓ scalability issues have been fixed (The entire rendering process has been rewritten to use the Forms API, which required backporting features available only in Drupal 6. The CSS and JS have been rewritten almost completely as a result of this.)
✓ perfect graceful degradation (Compare JS enabled VS JS disabled. This is actually just a byproduct of the above change.)
✓ ability to create new items in the hierarchy

Other changes:
✓ more granular control over Views exposed filters (for both the Taxonomy and Content Taxonomy implementations)
✓ Hierarchical Select for menu parent selection
✓ enhanced configuration form (more intuitive, and with a preview)
✓ abstracted configuration form, to prevent duplicate form code for multiple modules
✓ overview of all Hierarchical Select form item configuration forms
✓ display number of matching nodes
✓ actual CCK widget for content_taxonomy (already takes advantage of the abstracted configuration form)
✓ Views exposed Taxonomy filters: supporting the **ALL** option
✓ remove dependency on jQuery Interface
✓ if available, use HTML 5 client-side database storage to reduce the number of queries to the server

Changes since DRUPAL-5--2-1:

• #233310 by levavie: RTL support. Thanks\!
• #221660: i18ntaxonomy support

To see what's new and improved in this release, see my blog post about it.

Changes since DRUPAL-5--2-0-RC4:

• If _hierarchical_select_validate_selection() receives an array as the selection, and all items are invalid, then return -1 instead of an empty array, i.e. *always* return -1 if the selection was invalid.
• Fixed #222078: Content Taxonomy issues: merged levels and depth setting not working correctly
• Fixed #221210: Multiple select: impossible to remove selections of which the child term has multiple parents
• Implemented #218294: Support for the "error" class (i.e. when a required form item was left empty)
• Follow-up for #218294: hsid was hardcoded to zero.
• General cleanup: comment fixes, whitespace improvements.
• README improvements.
• Fixed #228193: Dropbox limit is not enforced server side.
• #227739: Original select randomly not hidden in Safari 3

I've been adding new features in almost every beta/RC. Not anymore now.

There's one known issue in this release. The reason it's not fixed yet: I've not yet been able to reproduce it.

New features:
- JS-enhanced Hierarchical Select settings form on the Vocabulary settings form
- New: Level label support when enforce_deepest is enabled; level labels will only be allowed in the root level.
- Smarter default settings for #required and #multiple for the exposed filter overriding.
- New: ability to set a root level label when enforce_deepest is enabled.

Improvements:
- Improvement: more consistent use of the "" option, available when: optional, or enforce_deepest is enabled, or multiple select is active and at least one item is selected.
- Improvement: the "" option is now automatically selected as soon as at least one item has been added to the dropbox (even if it's a required form item) – this required changes in the client-server interaction.
- Improvement: more reliable lineage reconstruction algorithm when save_lineage is enabled.
- Improvement: all_option setting now only has effect when multiple select is enabled (minor).
- Improved: Made selection of value 'label_X' trigger similar events as 'all' value: no server query required!

Bug fixes
- Fixed: the select items of the current HS aren't disabled when it's waiting for a server response.
- #212528: Weight of vocabulary has disappeared from the form
- #212052: When dropbox limit is reached: display warning, disable hierarchical select

New features
- Feature: support for subscriptions_taxonomy module.
