Clients not compatible with ACME v2 will progressively disappear from https://letsencrypt.org/docs/client-options/ (They will be greyed out first, and then removed).
The objective is to points users only to ACME v2 clients as the ACME v1 API is deprecated and will be removed (End of Life Plan for ACMEv1)
If you are the developer of an ACME Client or library:
- If your Client/Library is not yet compatible with ACME v2, you should consider supporting it
- If your Client/Library is already compatible with ACME v2, please make sure it has the
acme_v2
flag in https://github.com/letsencrypt/website/blob/master/data/clients.json (Example: https://github.com/letsencrypt/website/blob/361dac37f17d0a18791f7ee4f59f0e1942b143ba/data/clients.json#L140 )
If it doesn’t have have that flag and is compatible with ACME v2, please open a pull-request to update that information (and if relevant, with the version since ACME v2 was supported)
