AMT LION | AMT COBOL Runtime Various 329505

When a password was changed during login to the AMT Application Center, the security rules were not used.

Password security has been changed to be the same as those applying to the AMT Control Center.		 CHANGE AMT 78 Medium
AMT LION | AMT COBOL Runtime Various 329509

During Forms Authentication in an application, error messages allowed attackers to differentiate between valid and invalid usernames.

Security has been improved by always making AMT generate an identical, more generic error message when a login attempt fails.
Logging of the AMT Application Center and the AMT Application Server has been improved also, by logging failed login attempts AMT operators are enabled to detect brute force attacks.		 FIX AMT 78 Medium
AMT COBOL Runtime Various C2009-093

If a program went into an endless loop caused by code logic, the transaction timed out and the client became non-responsive. Catching this error did not result in a new connection for future transactions, so the AMT Transaction Server could not handle new requests.

If a time-out occurs the current agent is terminated and a new agent is created  for new transactions.		 FIX AMT 78 Low
AMT LION | AMT COBOL Runtime Various 329513

The Secure Cookie flag was missing from the AMT Control Center and the AMT Application Center.

Print dialog issues have been resolved, the following changes have been made:
1. Heading to the first groupbox: 'What to print' has been added;
2. First groupbox height has been increased to 170, so it matches the 'Code printing' groupbox;
3. 'Syntax' checkbox from the 'Code printing' groupbox has been removed since it had no functionality attached;
4. 'Print index (code only)' checkbox from the 'General options' groupbox has been moved to the 'Code printing' groupbox;
5. The printing of a selected block of code has been fixed, if the user has selected a block of code or is using the selected block 'To' and 'From' edit boxes;
6. Only the 'Items to print' dropdown is now shown in the 'General options' groupbox when a list of objects is shown, e.g. when the revisions screen is viewed.		 CHANGE AMT 78 Low

AMT COBOL AmtTools Reo C2010-035

For AMT COBOL, stored procedure 'asy_unique' has been changed to use a sequencer.

The use of a sequencer delivers better performance, because it does not need a separate database connection. The asy_unique stored procedure is now used to generate the EIBTASKN for former IBM/MicroFocus COBOL applications.		 CHANGE AMT 78 Low
AMT LION | AMT COBOL Developer Revision Control 329836

Objects in edit in another genset and not present in the current genset could not be fetched with 'GetNewest' even though there was a new checked in version.

AMT LION Runtime AmtScreens 329885

The preview of a text report could not be opened because the extensions were inappropriately used to determine the print type (graphical or text).

The extension is no longer used to determine the type of print output.		 FIX AMT 78 Low
AMT LION Runtime AmtScreens 329886

Double-clicking in the scrollbar in AMT Screens Job Management produced the selection of the entire item, instead of a simple scroll.

Double-clicks now only scroll the scrollbar.		 FIX AMT 78 Low
AMT LION Developer Code Logic 329843

Username could be overridden in the decommissioned StartReport.exe but this was not possible with the StartReport command.

Support for fields appearing in a view multiple times has now been implemented, fields are displayed and updated correctly now.		 FIX AMT 78 Low
AMT LION Runtime AmtScreens 329899

Exception 'Cannot start process because a file name has not been provided' was raised if the print file was missing, whereas a warning would be sufficient.

Now the appropriate message is shown and no exception is raised.		 FIX AMT 78 Low
AMT LION | AMT COBOL Control Center Configuration C2010-085

Using 'Read all jobs' in the AMT Control Center could cause problems with scripts being added/removed if a script existed in different folders.

AMT LION | AMT COBOL AmtTools Debugger C2010-087

The AMT Debugger has been migrated from .NET Framework to .NET Core.		 CHANGE AMT 78 Low
AMT COBOL Runtime Various C2010-088

The log files of the Transaction Agent and Server contain many trace messages, independent of the logging severity that has been set in the AMT Control Center. These trace messages should only be logged if the logging severity has been set to 'Debug'.

The trace messages are now logged only if the logging severity has been set to 'Debug'.		 CHANGE AMT 78 Low
AMT LION Developer Web Services C2010-089

Document Literal Unwrapped WSDL was not loaded correctly.

The AMT Communication Server and AMT Communication Manager have not started properly anymore since the migration to .NET Core (AMT 75). The problem was that the some of the required files for .NET Core were not downloaded by the AMT Communication Server.

The AMT Communication Server and AMT Communication Manager now work as expected.		 FIX AMT 78 Low
AMT COBOL Runtime Various C2010-102

AMT File Controller suffered from memory-leaks because threads handling named-pipe connections were not released, when a program disconnected.

The named-pipes connection threads are now disconnected on program closure.		 CHANGE AMT 78 Medium
AMT LION Developer Web Services 329907

If an XML complex type used a simple type, the latter should have been resolved to its base type, such as string, but it wasn't.

This has been corrected.		 FIX AMT 78 Low
