This is a maintenance release for libhitaki version 0.2 series.
It appears that it is not permitted to put GPL-2.0-only code into LGPL-3.0-or-later code.

Unfortunately, one of the UAPI headers from Linux kernel (include/sound/firewire.h) is included in libhitaki for backporting purposes. This header is licensed under GPL-2.0-only. The last change to the header was made for v6.3 kernel. While the headers have license exception (Linux-syscall-note), it resembles a GPL Runtime Library Exception (https://www.gnu.org/licenses/gcc-exception-3.1.en.html), which does not affect conveyance or so.
According to GNU, including GPL-2.0-only code in LGPL-2.1-or-later code results in GPL-2.0-or-later lincensing for the combined work. This release is for the purpose.
