Manually or semi-automatically improved training corpora quality for the languages indicated with the following ISO 639-3 related codes:
amh

kaz
lit
lus

For unknown languages, the code was changed from "xxx" to "und" which is ISO 639-3 compliant. A confidence score is also returned for "und".

If no relevant language list is given when HeLI is started using the -l option, the language models are read from two .ser file instead of the text files. This makes the identifier start more than three times faster on the development laptop.
