NLP fix #2: arithmetics support, complete CFG features (suppressed now)

History.md

@@ -1,11 +1,10 @@
 ### Issues currently under work:
 - 71: "3.99" is interpreted as 4.39am: justified
-- 66, 64, 28, 21, 18, 16, 15, 11, 5, 4: normalization: natural language for numbers and time
-- 70, 66, 63, 62, 21, 18, 15: support arithmetic, in <n><T>, with <op=and> etc.
+- 70, 66, 63, 18: full CFG and unit-specific arithmetics
 - 27, 26, 13: default, e.g. tonight, tomorrow at 11 -> at 11am, at midnight etc
 - 55, 52, 25, 2: causality, before, after, ago, from now, <bar> ops
 - 32: ranges
-- fix decimal number parsing
+- CFG pending takeover: month-specific carry into days, defaults (tomorrow = 9am), leap year
