Is there any reason that Tor in sys-whonix Qubes 4.1.2 / 4.2.0 RC4 is outdated?

Is there any reason why sys-whonix in Qubes 4.1.2 / 4.2.0 RC4 uses an older version of Tor and does not download a newer one when updating?

If you type

tor --version

in the sys-whonix terminal, you can see that Tor version is 0.4.7.13 (release date 2023-01-12). There have been several releases since then

0.4.8.1-alpha - 2023-06-01
0.4.8.2-alpha - 2023-07-12
0.4.8.3-rc - 2023-08-04
0.4.8.4 - 2023-08-23
0.4.8.5 - 2023-08-30
0.4.8.6 - 2023-09-18
0.4.8.7 - 2023-09-25

and the last is 0.4.8.7. How does the fact of using an older version of Tor affect the security of the overall system?
