On-Prem Continuous Delivery Release Notes

Prev Next

This article contains the Provider Connectivity Assurance Controlled Availability release notes. This on-prem software is updated continuously, giving customers access to the latest features and improvements. Software updates are released every few weeks.

As an alternative to the Controlled Availability release, on-prem customers who prefer the most stable Generally Available release can find the 25.7 software release notes here. The Generally Available release contains a fixed feature set and receives updates for security and bug fixes.

For customers who prefer a cloud-based offering instead of on-prem software, the latest Cloud content release notes are available here.

Known Limitations

Limitation

Description

Workaround

(Provider Connectivity Assurance Installation)

Dual stack deployments failed preflight checks when nameserver in /etc/resolve.conf resolves to an IPv6 address.

This can be worked around by putting a placeholder IPv4 address to pass the preflight check.
