v2.0.0 (2023-05-14)

This is a breaking release since the binaries to be installed have been revised and merged. The albatross-client-local is now albatross-client [--socket], albatross-provision-ca is now albatross-client sign or albatross-client generate. The albatross-client-remote is now albatross-client certificate. The albatross-client-bistro is now albatross-client <command> --destination <host> --ca ca.pem --ca-key ca.pem --server-ca cacert.pem.

And finally, albatross-tls-inetd is now albatross-tls-endpoint --inetd.

v1.5.1 (2022-08-31)

• Albatross_influx: drop leading ':' if path should be dropped (#114 @hannesm)

• FreeBSD packaging: rename albatross_stat to albatross_stats (#113 @hannesm)

• Refactor albatross BHyve stat collection (to avoid exception in List.combine) (#116 @reynir @hannesm)

• Albatross-client: allow passing a mac address explicitly to create for each network interface (#107 @reynir)

v1.5.0 (2022-05-16)

• Revise Name.t to use ':' as path separation, and allow '.' in labels. Previously the path was built by the common name in the X.509 certificate chain and the leaf certificate was appended (i.e. chain certificate "foo", chain certificate "bar", leaf certificate "my.unikernel" lead to the name "foo.bar.my.unikernel" -- and chain certificate "foo", leaf "bar.my.unikernel" lead to the identical name). Since the holder of the certificate and private key "foo" could issue at any point another intermediate certificate for "bar", this is not security critical -- but for resource management this was confusing and lead to some issues (policy could be violated). Now, the path separator is ':' (i.e. "foo:bar:my.unikernel" and "foo:bar.my.unikernel"). In addition, various test cases have been added, for vmm_trie, vmm_resources and also for old and new wire versions (albatross daemon state, command execution) to ensure that old clients continue to work with new server components. The wire version has been bumped to WV5, since the Name.t encoding was changed. (#111, @hannesm @reynir)

• CI execute tests (#112, @hannesm)

• fix URL to builder-web (https://builds.robur.coop) which dropped the opam-switch postfix in the URL (#113 @hannesm)
