Previous Releases

Version 5.54 corrected an important problem affecting applications running in ICOBOL 2 compatibility mode. This was first noticed by a client on the Rocky Linux 9 build, but it may also affect other builds. It also corrected a problem with runtime surrogates using SP2 failing to terminate if the client side crashes, which could slowly use up licenses.

If 5.54 is needed for its 32-bit support or because of a hardware protection device that is no longer supported, it can still be downloaded from our Archive Page. See the Release Notes for more information and additional helpful details.

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.

ICOBOL 4 support ended as of the end of 2015, so revision 4.89 is the last release of ICOBOL 4. Various ICOBOL 4 releases can still be downloaded from our Archive page.
