Leopard Reference Library
This page lists new and recently changed documents, including Articles, Guides, Reference, Release Notes, Sample Code, Technical Notes, and Technical Q&As. Most documents have a revision history, which details additions and changes to that document since the previous version. Look for "Revision History" at the bottom of the document or in the document's table of contents.

Items are listed in reverse chronological order by publication date. To see the list sorted by the type of revision, click Sort by Revision Type. Items published for the first time (First Version) will be at the top of the list, followed by items with new or changed content (Content Update), followed by items with small fixes, such as typos and format errors, but no significant content changes (Minor Change).

New and updated Reference Library documents are announced in the bi-weekly Apple Developer Connection News, available as an option to ADC members. See the Membership Overview page for details on joining.
