From f10fdfce6823f5b5bfd2f6bb1ec1ed3061406c7d Mon Sep 17 00:00:00 2001 From: Laura Martin Date: Tue, 31 Dec 2024 10:09:54 +0000 Subject: [PATCH 1/7] Use endpoint as default connection option (ADR-119) This implements ADR-119[1], which specifies the client connection options to update requests to the endpoints implemented as part of ADR-042[2]. The endpoint may be one of the following: * a routing policy name (such as `main`) * a nonprod routing policy name (such as `nonprod:sandbox`) * a FQDN such as `foo.example.com` The endpoint option is not valid with any of environment, restHost or realtimeHost, but we still intend to support the legacy options. If the client has been configured to use any of these legacy options, then they should continue to work in the same way, using the same primary and fallback hostnames. If the client has not been explicitly configured, then the hostnames will change to the new `ably.net` domain when the package is upgraded.
