Add xterm-kitty to color capable term list

Remove the mention of linking with libtermcap from einfo(3), and fix
some comments in libeinfo.c to more accurately reflect the new
situation.

 This file will contain a list of notable changes for each release. Note
 the information in this file is in reverse order.
 
+## OpenRC 0.54
+
+This release drops the support for the split-usr build option.
+Also, it drops the support for ncurses/termcap and uses ansi codes
+directly for color support on terminals that support them.
+
+## OpenRC 0.53
+
+The names of cgroups for services started by OpenRC are now prefixed by
+"openrc." This is done because some services, like docker, create their
+own cgroups.
+
+It is now possible to override the mount options used to mount the
+cgroups filesystems.
+## OpenRC 0.52
+
+This release drops the "runscript" and "rc" binaries.
+These binaries have been deprecated for multiple years, so it should be
+fine to remove them at this point.
+
+There was an issue before this release with the default setting for
+cgroups being inconsistent. This is fixed.
+
+Start-stop-daemon did not work correctly on Linux 6.6 systems.
+This has been fixed in this release as well.
+
+## OpenRC 0.51
+
+The default RC_CGROUP_MODE has been updated to unified.
+This benefits users since it will assign each service to its own cgroup,
+making resource nanagement better over all.
+
+OUTPUT_LOGGER and ERROR_LOGGER have been implemented for
+supervise-daemon. For mor einformation on these settings, please check
+the man page.
+
+## OpenRC 0.50
+
+This is a bug fix release which fixes a significant performance issue on
+musl libc systems.
+
+## OpenRC 0.49
+
+This release adds support for glibc's builtin 
+strlcpy, strlcat etc functions, which will be in posix next.
+Also, it fixes completions.
+
+
 ## OpenRC 0.48
 
 This release is a maintenance release; it has no user-facing changes.
