 ## Changelog
+- #### 2.8.2 released 25 February 2025.
+   - [#744](https://github.com/AbsaOSS/cobrix/issues/744) Added the ability to specify default record length for the record length field mapping:
+     The default record length can be specified by assigning a value to the underscore key `"_"`. For example:
+     ```scala
+        .option("record_format", "F")
+        .option("record_length_field", "RECORD_TYPE")
+        .option("record_length_map", """{"A":100,"B":200,"_":500}""")
+     ```
+
 - #### 2.8.1 released 27 January 2025.
    - [#730](https://github.com/AbsaOSS/cobrix/issues/730) Added more code pages with euro character in https://github.com/AbsaOSS/cobrix/pull/741.
    - [#740](https://github.com/AbsaOSS/cobrix/issues/740) Extended binary type support to make sure unsigned binary fields can fit Spark data types in https://github.com/AbsaOSS/cobrix/pull/742.
