Incompatibilities introduced in 3.21

Password Policy Changes

The password policy has been updated to enhance security within the application. These changes apply exclusively to the creation and validation of passwords within the application.

Password quality is not checked during user authentication or when importing users from Active Directory, as these processes rely on external password policies. Therefore, this update has no impact on authentication or user import functionality.

The specific changes are:

Increased PASSWORD_MIN_LENGTH from 8 to 12
Set LOWERCASE_MIN_COUNT and DIGIT_MIN_COUNT to 1
Expanded SPECIAL_CHARS to include all printable ASCII special characters

Datapoint names with quotes

Fixes have been applied for datapoint names that include quotes. In the ASCII file generated with the Ascii -out option, quotes in DP names will be escaped using double quotes ("").

This issue does not occur with ASCII V2 files, as they do not require escaping quotes.

Note that DpType and MasterDP names must not contain quotes, as this is not supported.

Important:

If you have existing ASCII V1 files with quotes in datapoint names, you will need to modify them by adding an extra double quote ("") before each quote character.
