 - Internal BoM: option to avoid merging components with empty fields.
   Is named `merge_both_blank` and defaults to true.
+- Internal BoM: when a `Value` field can't be interpreted as a `number+unit`,
+  and it contain at least one space, now we try to use the text before the
+  space. This helps for cases like "10K 1%".
 
 ### Changed
 - Internal BoM: now components with different Tolerance, Voltage, Current
