I have not had time to download Safari 5.0.1 yet but here is what CNET said about it.
“Apple has released an update to Safari 5, which addresses a number of issues with the initial release, including the problem with black backgrounds appearing when generating mail attachments with scripts, and the potential security vulnerability with autofill that was recently uncovered. In addition, the program has a built-in link to Apple’s new extensions gallery for people to download and install extensions.
The update is a 47MB download and is available through Software Update or as a standalone installer from the following web page:
In addition to the black background bug (which Apple mentions again in this knowledgebase article), Apple has fixed the recent autofill bug that posed a security threat for websites that could automatically get personal information from the user’s address book, so if you have turned off autofill because of previous reports, you can turn it back on after applying the 5.0.1 update. Other security fixes in this update are listed in this security bulletinregarding the update.
In addition to the security fixes, Apple addressed compatibility issues with various websites including RollingStone.com, Facebook.com, and Crateandbarrel.com when using Safari Reader, Flash, and when performing other functions like printing.
The Extensions gallery is quite intuitive, and installing extensions is as easy as browsing for them and then clicking the “Install” button. Once clicked, the extension will appear in the Safari toolbar immediately and be ready for use. While extensions can easily be installed through the gallery, the only way to manage and remove them is through the Safari preferences section for the extensions.
A full list of the changes in this update are the following:
- Customize Safari with features created by third-party developers Find extensions in the Safari Extensions Gallery, accessible from the Safari menu and extensions.apple.com
