Hi Robert,
It seems highly unlikely that 7c05d44 is the causal commit. The
difference that is causing the error is due to a change the the
representational structure of tables from 9.7 -> 9.8. In 9.7 (table
'(("entry11" "entry12" "entry13") ("entry21" "entry22" "entry23")))
and in 9.8 ((head1 head2 head3) hline (entry11 entry12 entry13)
(entry21 entry22 entry23)). I don't see anything in 7c05d44 that would
cause the change from the (table ...) format to the (... hline ...)
format. It looks to me like cab81f2428880b293e780915cf9762cc59692091
is the commit in question: org-babel: Improve parsing of colnames in
tables with horizontal lines. Best,
Tom
