.. Release Notes from this point.

:critical:`[Critical]` Application hang after failing to post a local credential validation event during DomainParticipant enablement
-------------------------------------------------------------------------------------------------------------------------------------
*DomainParticipant* enablement failure caused by a local credential event 
error caused an application hang. The logged message included the following 
errors:

.. code-block:: none
    
    ERROR [[...]|CREATE DP|ENABLE|ENABLE PRES DP|LC:Discovery,Security] PRESParticipant_enable:FAILED TO POST | An event for [...] validation.
    ERROR [[...]|CREATE DP|ENABLE|LC:Discovery,Security] DDS_DomainParticipantPresentation_enable:!create enable
    ERROR [[...]|CREATE DP|ENABLE|LC:Discovery] DDS_DomainParticipant_enableI:!enable participant
    ERROR [[...]|CREATE DP|ENABLE] DDS_DomainParticipantFactory_create_participant:ERROR: Failed to auto-enable entity

Trying to use or delete the *DomainParticipant* caused the application 
hang.

:major:`[Major]` Excessive resource consumption in certain scenarios *
----------------------------------------------------------------------
In certain situations, the *Security Plugins* consumed excessive
resources in threads responsible for local security artifacts' renewal
and expiration. The primary symptom was high CPU consumption, which
slowed *Connext’s* runtime execution. Examples of situations triggering
this problem included a period of time between creating a
*DomainParticipant* and fully enabling it, or disabling OCSP. The latter
could be triggered by setting the ``<ocsp>`` tag within the
`identity_credential_authority_validation <https://community.rti.com/static/documentation/connext-dds/7.7.0/doc/manuals/connext_dds_secure/users_manual/p2_core/authentication.html#identity-credential-authority-validation>`__
tag to ``IGNORED`` or by setting the
``com.rti.serv.secure.authentication.ocsp_ignored``
`property <https://community.rti.com/static/documentation/connext-dds/7.7.0/doc/manuals/connext_dds_professional/properties_reference/property_full.html>`__
to ``TRUE``.
