If you downloaded and have been using Enigma 2.3 or 2.3.1 you should immediatly stop adding files to vaults and extract all files from them. Enigma 2.3 had a very serious bug which under limited circumstanced could cause data loss. Create new vaults with Enigma 2.3.2.
The rest of this document is of interest only if you have previously used Enigma 2.2.1 or earlier.
User Interface Changes
=====================
Enigma 2.3 has substantial user interface changes. Because buttons have moved around and dialog boxes have been redesigned any macros you use with Enigma such as QuickKeys or AppleScript probably will need to be tweaked.
Selecting files in a vault has changed. Click and drag to select multiple files at once (NOT Shift-Click). Shift click and drag to make disjoint selections.
Compatibility Issues
===================
Basically Enigma 2.3 remains fully compatible with previous versions. But there are a few caveats:
Enigma 2.3 now remembers creation and modification dates on files. Those dates are restored when the file is decrypted. Files created by earlier versions of Enigma have invalid data where Enigma 2.3 stores this information. Therefore files restored by Enigma 2.3 which were created by previous versions will have bogus creation and modification dates (often sometime in 1904). This is harmless but can be annoying. The only way to avoid this problem is to decrypt any old files with your previous version of Enigma and then reencrypt them with version 2.3
Vaults created with earlier versions of Enigma are compatible but do not benefit from the new features: folders, comments, 200 file limit [Full DES only], etc... Create new vaults to get the new features.
Enigma 2.3 can not be used to edit Self Extracting Vaults created by earlier versions of enigma. The old self extracting vaults will continue to work just fine they just can't be modified.
Documentation
==============
The documentation has been completely redone, take a few minutes to read through it.
