Yes. According to the API documentation [1] the function was added in
libpsl 0.11.0. CentOS 7 contains version 0.7.0. Before 8.6.0, curl
used a different API to get the version number. This was changed in
commit 72bd88adde0e8cf6e63644a7d6df1da01a399db4.
There is no macros available to check for the version in the libpsl
version in CentOS 7, but newer versions seem to have them. Using them,
one can do something like the attached to get it working again on
CentOS 7. The --version display reverts back to the previous format:
$ ./src/curl --version
curl 8.6.0-DEV (x86_64-unknown-linux-gnu) libcurl/8.6.0-DEV OpenSSL/1.0.2k-fips zlib/1.2.7 brotli/1.0.7 zstd/1.5.2 libpsl/0.7.0 (+libicu/50.1.2)
