Which VCard versions are supported?

[sphh]

I am referring to #832 (DavDroid: Radicale no VCard/4 support). There the problem was solved by implementing a stricter standard on the clients side.

This still leaves me wonder, which VCard versions are supported. And why the Radicale server does not advertise the supported version, as mentioned in 's comment @n00b42 #832 (comment)?

1. Please could you specify the supported VCard versions.
2. If the VCard version > 3.0 are supported, please could you let Radicale advertise these versions (it might also be a good idea to advertise the version 3.0 and not relying on the automatic fall back).

I did a bit of research, and the reason why Radicale doesn't support vCard 4.0 is because its dependency vobject doesn't support 4.0. You can take a look here for more info: skarim/vobject#106

It does however say that reading v4 works. I wonder if that is sufficient for v4 support in Radicale.

vObject intends to support vCard 2.1, 3.0, and 4.0 in the near future. Work on complete 4.0 support will begin soon.

Can you tell us about the current status of work on the implementation of new versions of VCARD?

There is a PR open: py-vobject/vobject#124
And Radicale is prepared since 3.6.0 assuming vobject >= 1.0.0 has it included and also advertise 3.0 for now.
