    Disable new command checking with latexrelease
    
    When rolling forward from 2020-10-01 (and very likely only if rolling to
    2021-05-01) there will be errors because the ltcmd module was introduced
    but the public commands are the same as the ones pre-loaded 2020-10-01,
    so this disables that checking temporarily for this specific case.

+% Rolling forward from 2020-10-01 is tricky because the entire |ltcmd|
+% module is new, but the user-level commands have the same name, so only
+% these will clash.  To work around that, in |latexrelease| mode we will
+% (temporarily) disable \cs{__kernel_chk_if_free_cs:N} for this final
+% part of the code, then restore at the end.
