Unfortunately, a late last-minute bug was found in some fast-moving
distributions we support that uses a modern version of GCC.
The compilation error was due to the name "bool" now being reserved by C23.
During the release procedure a backport was made to solve the issue.
We missed a flaw in this approach and managed to break the ABI
compatibility:

Message from VCC-compiler:
VMOD <name>: bad metadata
         (Syntax != 2.0)
         File name: <path>.so
 ('<path>.vcl' Line X Pos Y)
 import <name>;
 --------####-
 Running VCC-compiler failed, exited with 2
 VCL compilation failed
 Command failed with error code 106


We apologize for the inconvenience, but the end result is that all VMOD
have to be recompiled for the 7.6 and 7.7 branches of Varnish.
See the updated release note:
