Varnish Enterprise 6.0.18r7 has been removed Announcement

Published October 29, 2026.

Release removed from the repository

The release of Varnish Enterprise version 6.0.18r7 has been removed from the package repository due to regressions discovered in the latest release.

This release updated the VCL compiler, which introduced regressions in the handling of ACLs. Some ACLs that loaded with 6.0.18r6 now fail to compile, for example an entry with non-zero bits in the masked part of the address, such as "192.0.2.1"/24. We have identified further issues with ACLs in this release.

We recommend that all users of 6.0.18r7 downgrade to 6.0.18r6. Downgrade all Varnish Enterprise packages together. Third-party VMODs built for 6.0.18r7 are not compatible with 6.0.18r6 and must be replaced by builds for 6.0.18r6. VCL that was modified to use features new in 6.0.18r7 must be reverted before it can be loaded by 6.0.18r6.

A follow-up release addressing these regressions is being prepared.
