Description
FairCom DB allows you to write callbacks in C to modify a record before the server stores it in the database.
In V13, a record update callback can be executed synchronously or asynchronously during one of the following events:
Synchronously before a record in committed.
Synchronously after a record has committed.
Asynchronously after a record has committed.
You also have the option of asynchronously running code that does other tasks instead of updating.

FairCom added new actions to the MQ API to enable you to have MQTT's pub/sub capabilities while using the HTTP protocol. FairCom uniquely allows you to centrally manage sessions for all MQTT clients. The "getMessagesFromMqttTopic" action allows you to do event streaming in FairCom products similar to how Kafka does it.

FairCom has increased data flexibility and efficiency by creating a new variant data type. You can now store any type of data in a variant column, including a string, number, date, time, Boolean, image, JSON, XML, or user-defined data type, along with metadata that tells your application precisely what you stored in the column as well as the format and encoding of the data value. The database can also automatically store a value with multiple encodings along with the metadata that tells your application how it is encoded so your application can decode it.

-unload: Allows you to read records larger than 64KB by exporting data from a COBOL data file to a sequential or ASCII file.
-info: Displays information about a file.
-applyrules: Applies rules to an XFD or XDD file.
-maxsize: Specifies a maximum size limit for a file.
Enhanced commands:
-conv: Stores or retrieves the numeric storage convention of a file. Enhanced to be able to do this even if the convention ID parameter is omitted.
-ddf2xdd: Transforms Btrieve Data Dictionary Files (DDFs) into c-tree XDD files containing schema information about the data and index structures. Enhanced to be able to do this even when the name in the DDF does not match the file name.
-alter: Changes the record schema of a file. Enhanced to display new record length on success.
-copy: Copies a file. Enhanced not to automatically overwrite existing destination files.

Partitioned files in RTG
Description
RTG configuration option <datafilesuffix> can now be configured to disallow duplicating file name extensions using new options <datafilesuffix append> and <datafilesuffix casesensitive>. Previously, this could happen accidentally due to the automatic appending of a file name extension even if there was already one present, causing confusion (for example, accidentally naming something "filename.dat.dat").
