Includes Safari 5.1.7, more RAW support
Following several weeks of developer testing, Apple has released the completed version of OS X 10.7.4. Now available though Lion's Software Update mechanism, the upgrade deals with several security, reliability and compatibility problems. Most notably it fixes a security issue in FileVault which could potentially expose a person's passwords in plain text.
Files should should more reliably copy over to servers, particularly SMB servers. Compatibility with third-party British USB keyboards has been improved, and Apple has solved a glitch that would force the "Reopen windows when logging back in" setting to on. Other issues dealt with involve Active Directory accounts, PPPoE connection sharing, using proxy auto-configuration files, permissions and the Get Info inspector, and WebDAV server connection performance. Bundled with the update is the more stable Safari 5.1.7, and expanded RAW format support.
The client download is available in delta and combo versions measuring 692.68MB and 1.4GB, respectively. The server client and combo releases are 738.71MB and 1.49GB.
