+  The mail/thunderbird port switched to Thunderbird's new release train,
+  with frequent major releases (ca. 4-weeks-cycle). Users wanting to
+  stay with the 128-releases for now and the ESR releases in general
+  should switch to the mail/thunderbird-esr port.

+Author: Christoph Moench-Tegeder <cmt@burggraben.net>
+
+    Bug 1948776 - handle non-existence of MAP_NORESERVE for FreeBSD, r=afranchuk,jld,nika
+    
+    The MAP_NORESERVE flag does not exist in FreeBSD. As the minimally-
+    invasive workaround, I decided to remove that flag directly in the
+    mmap() calls, instead of defining our own MAP_NORESERVE as 0
+    possibly far away and not obviously connected to these places.
