- Massive optimization of data layer -- with ~11,000-item test library on a Mac Pro, decreased initial Zotero pane loading from several minutes to ~10 seconds. This included some small API changes and new methods (e.g. Items.cacheFiles()) in the data layer, but most of it was changing the way loading and caching of data worked internally.
- Moved unique itemData values out to separate itemDataValues table for better normalization
- Updated itemTreeView.sort() to be able to sort a single row into the items list for performance reasons -- itemTreeView.notify() now only sorts a single row when possible (and sometimes doesn't need to sort anything). This should make general interface use dramatically less sluggish with large libraries.
- Consolidated purging on item deletes, which should speed up multi-item deletes quite a bit -- clients should use Items.erase() instead of Item.erase(), since the former calls the new Items.purge() method (which calls the various other purge() methods) automatically
- Notifier no longer throws errors in notify() callbacks and instead just logs them to the Error Console -- this way a misbehaving utility (or Zotero itself) won't keep other observers from receiving change notifications
- Better handling of database corruption -- if an SQL query throws a file corruption error, Zotero adds a marker file to the storage directory and displays a message prompting the user to restart to attempt auto-repair--and, most importantly, no longer copies the corrupt file over the last backup.
- A "Loading items list..." message appears over the items list (at least, sometimes) while data is loading -- useful for large libraries, but may need to be fine-tuned to not be annoying for smaller ones.
- Note titles are now cached in itemNoteTitles table
- orderIndex values are no longer consolidated when removing items from collections -- it just leaves gaps
- Fixed shameful bug in getRandomID() that could result in an item with itemID 0, which wouldn't display correctly and would be impossible to remove
- Fixed autocomplete and search for new location of 'title' field
- Added proper multipart date support for type-specific 'date' fields
- Made the pre-modification array passed to Notifier observers on item updates actually be pre-modification
- New method Zotero.ItemFields.isFieldOfBase(field, baseField) -- for example, isFieldOfBase('label', 'publisher') returns true, as does isFieldOfBase('publisher', 'publisher')
- Restored ability to drag child items in collections into top-level items in those collections
- Disabled unresponsive script message when opening Zotero pane (necessary for large libraries, or at least was before the optimizations)
- Collections in background windows didn't update on item changes
- Modifying an item would cause it to appear incorrectly in other collections in background windows
- Fixed an error when dragging, hovering to open, and dropping a note or attachment on another item
- Removed deprecated Notifier methods registerCollectionObserver(), registerItemObserver(), unregisterCollectionObserver(), and unregisterItemObserver()
- Loading of Zotero core object can be cancelled on error with Zotero.skipLoading
- Removed old disabled DebugLogger code
- New method Zotero.log(message, type, sourceName, sourceLine, lineNumber, columnNumber, category) to log to Error Console -- wrapper for nsIConsoleService.logMessage(nsIScriptError)
- New method Zotero.getErrors(), currently unused, to return array of error strings that have occurred since startup, excluding CSS and content JS errors -- will enable an upcoming Talkback-like feature
- Fixed some JS strict warnings in Zotero.Date.strToMultipart()
