This release is compatible with the previous one.

Features

You can now export your entire transaction history to the CSV format, so you can import it into LibreOffice and do your own analysis. The button for that is on the upper right corner. Press it, then select "Share to CSV" and select a program to share the file with - for exampe, your favorite cloud provider or an e-mail application.
You can also import CSV files into piggybudget now. To do this, select a file, from an e-mail for example, and use the "Share" or "Send to" feature from the respective application. For CSV files, piggybudget should show up as a possible application to share with.

Fixes

History: the pop-up menu icons are gone now (they were quite nonstandard apparently) and the font is a little smaller now.
History: the section header font is now black instead of grey.
Stats: The "month" and "week" selectors for incomes and expenses are now not linked anymore.
