I have four File Headers in the CSV to import, following instructions in File Headers in the Anki Manual.
Importing now ignores the following separators (commas, in my case) with this recent release. At least it seems to. However, only the separator, html, and deck headers were honoured.
The notetype header was not honoured.
However, if I manually go load the CSV into a text editor and delete all the following separators, the import works fine.
The File Headers of my CSV follow.
#separator:Comma,,,,,,,,
#html:true,,,,,,,,
#notetype:Basic (optional reversed card) EO AK,,,,,,,,
#deck:EO All Official Esperanto Words and Roots,,,,,,,,
File Headers of another file, which also shows the same behaviour (i.e. that the Note Type is ignored).
#separator:Comma,,,,
#html:true,,,,
#notetype:Basic (optional reversed card) EO 1000,,,,
#deck:EO 1000 Most Frequently Occuring Words,,,,
