Important behavior changes
MRA authorizations are now rate controlled by default, to reduce the load of unnecessary authorizations on
the VCS. Take care when you upgrade because your current endpoint software may be reauthorizing more
often than necessary, which could result in the VCS issuing HTTP 429 "Too Many Requests". If you
routinely see this error after upgrade, you can edit the rate control settings at
the VCS. Take care when you upgrade because your current endpoint software may be reauthorizing more

Changes in X8.5.1
since the previous release.
This maintenance release also builds on features introduced in the X8.5 release, as follows:
SSO over MRA
Single Sign-On over MRA is released with X8.5.1; this feature was previewed in X8.5. The Features in
X8.5.n section has been updated with information about SSO over MRA.

The VCS Control now defaults to SHA-256 for signing SSO requests it gives to clients, and you can change
it to use SHA-1 if required. In version X8.5, when the SSO feature was previewed, the VCS Control defaulted
to SHA-1 and there was no way to select a different algorithm.

Note: If you were using the SSO feature with X8.5, this change may cause it to stop working after upgrade to
X8.5.1. You have two options to resolve this: leave the new default on the VCS Control, and you may need to
reconfigure the IdP to expect requests to be signed with SHA-256 (recommended for better security); the
other option is to revert the VCS Control's signing algorithm to SHA-1 for your IdP (go to
