Version 1.4.1 yesterday had a regression (#82 Drag&Drop does not work) and a race condition (#54 print only prints first page) which has
now been corrected, addtionally to #83 NaN for VAT amount and rounding amount.This corrected version 1.4.2 of our open-source e-invoice reader "Quba" should be sufficient to get you into the next year, the next regular update is only planned for Q1/2025.Apologies for any inconvenience caused.

This release works also on intel macs (#23) and print works again (#54). Additionally, the language is now set to system default upon installation (#78), it also works with XML which is embedded as file list (#68), Electron has been upgraded from v20 to v33 (#58), there is now also a MSI installer for windows (#53) and the license is now stated in the about window (#63).

Quba is a invoice viewer supporting Peppol-, CII-, UBL-, XRechnung- and Factur-X/ZUGFeRD.Through sponsorship of the new version 1.4 can now also display orders in the Order-X-format.The XML part of hybrid invoices and orders is now also shown immediately next to the PDF-view.The removal of the "extra click" which was so far neccessary for this purpose has been removed as part of the preparation for the planned mandatory german domestic B2B-e-invoicing.Quba is open source, can also validate invoices and orders using Mustangserver when online and can be downloaded free of charge for Linux, Windows and Mac.
