-- `print` and `close` now show a trailing decimal mark on cost amounts also,
-  when needed to disambiguate a digit group mark.
-

-  appropriate (fixes a regression in 1.25).

-
-### hledger-ui 1.33.1
-
-- Require vty-windows-0.2.0.2+ to avoid display problems in recent
-  MS Terminal on Windows.
-
-- process >=1.6.19.0 seems not strictly needed and is no longer required,
-  improving installability.
-  [#2149]
