Adobe has updated Acrobat XI and Reader XI to version 11.0.02 solely to improve the security of the two apps. The updates address critical vulnerabilities in versions 11.0.01 and earlier, vulnerabilities that could enable an attacker to take control of your system (detailed over at The Next Web). The update for Acrobat XI is just 11.9 MB; meanwhile you can choose between the delta updater (25 MB) or the full installer (76.6 MB) for Reader XI. Additionally, Adobe recommends that users of older editions of Acrobat and Reader update their software as well, with Acrobat getting version 10.1.6 (13.5 MB) and version 9.5.4 (10.8 MB). If you can’t update to Reader XI 11.0.02, you can similarly choose version 10.1.6 (17 MB) and version 9.5.4 (5.4 MB for Intel, 5.6 MB for PowerPC). ($449 new for Acrobat XI Pro, free updates)
Copy Existing Filename to 'Save As' Field
While many utilities provide file naming automation, they're mostly overkill for those cases when you need to make small variations in file content while ensuring the documents group together in a "by name" list.
In the Save As dialog, the default name is the current document name. You can quickly change this to match any existing file.
1. Make the list of files the active element.
2. Click on a grayed-out filename, which momentarily turns black.
3. The Save As field now contains the filename you just clicked.
You can modify the name (adding, say, "version 3") or overwrite that existing file you clicked.
