Version 5.0 beta 11 is ready for testing. Most improvements are done by your feedback, thank you very much for support.
What is new:
• Fixed importing azz version 4 files issues.
• Improved popup menus.
• Improved encryption:
azzdb files are encrypted by default using aes-256 cipher algorithm which provides top strong confidentiality and Integrity. However, this happens at the price of a certain performance reduction, especially for a large database.
If azzCardfile is running slowly after encryption, try to encrypt it using alternative encryption mode.
The aes-ecb cipher algorithm provides comparably weak confidentiality and no Integrity. However, it has the best performance across other encryption modes and is secure enough in most of cases.
• Created a choice of cards selection for printing and exporting (current, selected, all, titles only)
• Small improvements and bug fixes.

Now azzCardfile 5 has almost all functionality, next version will be final or pre-release.
