improvements for custom certificates (CustomCertService is shut down when not needed anymore)
update to okhttp/3.9.0 (including ALPN support)
minor improvements and bug fixes
With this new update, I am seeing an issue where new subscribed events while syncing do not show up at the right time. They show up the night before as a short event. This was an issue with a version about a year ago and it seems to have returned in this version.
