* The key file specified in /etc/crypttab (the third field) may now
refer to a UNIX socket path. The key is acquired by connecting to
that socket and reading from it. This allows the implementation of a

acquired by connecting to that socket and reading from it. This
allows the implementation of a service to provide key information
dynamically, at the moment when it is needed.
* Support has been added for extracting the PKCS#11 token URI and
encrypted key from the LUKS2 JSON embedded metadata header. This
allows the information how to open the encrypted device to be
embedded directly in the device and obviates the need for
configuration in an external file.

PKCS#11 token URI and encrypted key from the LUKS2 JSON embedded
metadata header. This allows the information how to open the
encrypted device to be embedded directly in the device and obviates

* LUKS devices may now be unlocked using TPM2 hardware.
* systemd-cryptsetup gained support for unlocking LUKS2 volumes using
TPM2 hardware, as well as FIDO2 security tokens.
* systemd-repart may lock partitions using TPM2 hardware. This may be
useful for example to create an encrypted /var partition bound to the
machine on first boot.
* A new systemd-cryptenroll tool has been added to enroll FIDO2+PKCS#11
security tokens to LUKS volumes, list and destroy them. See
https://www.freedesktop.org/software/systemd/man/systemd-cryptenroll.html.

It also supports enrolling "recovery keys" and regular passphrases.
* The libfido2 dependency is now based on dlopen(), so that the library
is used at runtime when installed, but not if not.
* systemd-cryptsetup gained support for two new options in
/etc/crypttab: no-write-workqueue and no-read-workqueue which request
synchronous processing of encryption/decryption IO.
* The manager may be configured at compile time to use fexecve instead
of execve when spawning children. Using fexecve closes a window

with high-priority event sources that might starve out others. See
the new man page sd_event_source_set_ratelimit(3) for details.
* systemd.link files gained a [Link] Promiscuous= switch, which allows
the device to be raised in promiscuous mode.
