In the RAR file linked by bulba99, there is a .doc file that contains a lot more information than the shorter history notes. It looks to be all internal bug details addressed in each build not the simpler summaries.
Running it through google translate for some of the text that wasn't dual-language already, got the below doc for the changes since Version:00.04.03.02.02 Date:2015-09-07. If you want to see older details just browse the rest of the doc.
It is very weird though the dates don't match up with those in the normal history notes and while some versions exactly match the list of fixes (example: v00.04.04.01.01 has the same details in both but different dates: 2016-08-19 vs. 2016/09/14) others seem totally different. I'm curious why there is such a mismatch?
