3. What’s New in 7.3.0 LTS

TLS Support 7.3.0 LTS is a long-term support release that is built upon and combines all of the features in releases 7.0.0, 7.1.0, and 7.2.0 (see Previous Releases). See the Connext Releases page on the RTI website for more information on RTI’s software release model.

3.1. Upgraded OpenSSL to version 3.0.12

The following third-party software used by the TLS Support has been upgraded:

Third-Party Tool	Old Version	New Version
OpenSSL	3.0.9	3.0.12

In addition to the upgrade, the OpenSSL target packages for Android, Linux, and Windows now include the FIPS module configuration file and provider library (the packages were built using the enable-fips option and make install_fips command described in this OpenSSL README file). You can use the fipsmodule.cnf and fips_3_0.so (Android), fips.so (Linux), or fips.dll (Windows) files to validate that TLS Support works with the FIPS provider. Keep in mind that, according to openssl.org, the latest FIPS-validated OpenSSL version is 3.0.8.

In this release, TLS Support is only available as a set of nddstls libraries built against OpenSSL 3.0.12 (which is supported until September, 2026).
