There're breaking change in isync 1.4. The update was intentionally postponed, I think (1.3.4 and 1.4 was released in the same day)

[paper42]

from what I can see in the changelog, the breaking changes are possibly:

• removed isync compatibility wrapper
• if a server supports only SSLv3 and/or lower (or only TLS1.3), mbsync could stop working and config has to be updated (only for very specific circumstances)

What is the state of this ? Alpine already got 1.4.1 and the configuration got breaking changes. Keeping the old version in void is painfull
