💡 Highlights
Will 2025 be the year of IPv6? Let's not try to answer this controversial question and just say that the main change of this pre-release is drum roll the official support of IPv6!
Most of the code was already IPv6-aware, but in some places IPv4 was assumed so these all have been adjusted to work with both IP versions.
Note that by default, IPv6 support is disabled, we've introduced the IPv6Allowed boolean option in bastion.conf that you must set to true to allow egress connections in IPv6. We've also taken this opportunity to add an IPv4Allowed option, which is enabled by default, you can set it to false should you want to have a strictly IPv6-only bastion!
A lot of tests have been added to ensure everything works correctly with this change, but as this is still an important change, and only a few tests have been done in-the-field yet, this'll be a pre-release for a few weeks.
We've also taken this opportunity to make a few other changes, such as:
- speeding up the
is_valid_ipcheck (35% speedup, noticeable for groups with thousands of ACLs) - set
ECDSAas the default algorithm for generated egress keys instead of RSA, for new installs only (defaultAccountEgressKeyAlgorithm)
Some work has also been done around the unit tests (using the more standard TAP::Harness) and functional tests (speeding them up).
A more complete list of changes can be found below, for an exhaustive (and boring) list, please refer to the commit log.

💡 Highlights
A new restricted command has been added: assetForgetHostKey, which is the bastion-wide version of the selfForgetHostKey command. In other words, it removes a given asset's hostkey from all the bastion accounts' personal known_hosts file. This is particularely useful when a given asset is reinstalled or its IP is being reallocated, and you've left the bastion-wide default of StrictHostKeyChecking to 'ask': in that case, if this command is not used after the asset hostkeys have changed, each account will have to use selfForgetHostKey on their own, to tell the bastion that the previously known hostkey should be forgotten.
This new command makes it possible to sync the reinstallation of an asset with a bastion-wide reset of its hostkeys (e.g. using an automation account that will be granted the use of the assetForgetHostKey command), without requiring all the other accounts to do it on their own. On their next connection, the other accounts will just have to accept the new hostkey (if StrictHostKeyChecking is set to ask, which is the default), or the new hostkey will be auto-accepted in the absence of a known one (if StrictHostKeyChecking is set to accept-new).
A long-standing but has also been fixed with stalling downloads using scp (#486).

💡 Highlights
This releases updates the supported OS list as follows:
- drop support for Ubuntu 16.04 and CentOS 7
- add support for Ubuntu 24.04 LTS and OpenSUSE Leap 15.6
Appart from the supported OS list, this release has a lot of changes, the most important ones are summarized below.
Add support of rsync (#301). Now, for specific protocols (such as scp, sftp and rsync), instead of having a dedicated option for all the plugins, they share a new --protocol option, which will permit adding more protocols if needed, without requiring adding new named options. The previous options are still supported and will keep working, even if the documentation has been updated to only reference --protocol.
Add support of wildcards (also called "shell-style globbing characters"), namely ? and *,
when using the --user option for plugins such as groupAddServer, groupDelServer, groupAddGuestAccess,
groupDelGuestAccess, accountAddPersonalAccess, accountDelPersonalAccess, selfAddPersonalAccess,
selfDelPersonalAccess. This implements #461.
Add a new per-account option: egress session multiplexing (usage of the ControlPath and ControlMaster ssh client options), for accounts opening a large number of connections to the same hosts, such as is the case with e.g. Ansible usage. You'll find it in the accountModify documentation.
Worth noting is also a new plugin: groupSetServers, to permit setting the ACL (asset list) of a group in one shot, to attain a given wanted list, instead of having to rely in several groupAddServer and groupDelServer calls.
We also enable the sntrup761x25519-sha512@openssh.com KEX algorithm by default on shipped versions
of sshd_config and ssh_config, read the specific upgrades instructions linked below if you're interested and this is not a new installation.

💡 Highlights
The main noteworthy change in this release is the support for so-called Secure Keys 🔑 (FIDO2) for ingress connection. If you're upgrading from a previous version, you'll have to enable support in the configuration file, refer to the specific upgrade instructions below. This is enabled on new installations by default.
How to generate and use a Secure Key from your hardware token to secure SSH access is usually detailed in the documentation of your hardware key vendor (For example Yubico).
