ICOBOL 5 Releases

Interactive COBOL Revision 5.53
(April 4, 2025)

Revision 5.53.01 is the current release of the ICOBOL 5 product. Version 5.53.01 corrects an additional problem in the network code in 5.53 that was noticed shortly after its release (we missed one place that needed the fix). Release 5.53[.01] was a minor update to release 5.52, which includes fixes in ICNETD, the surrogates, the ODBC driver, and the Linux networking code.

Release 5.50 included bug fixes, significant updates to the SP2 components, openssl, and updates to the underying toolsets used to build the system. We do recommend that you test this release if you are upgrading from a pre-5.50 release. See the Release Notes for more information and additional helpful details.
