A rabbit checks the endpoint trail,
Past primary hosts and fallbacks pale.
Five new paths through fields of green,
Hostname endpoints stay serene.
Tests hop along to check each route,
And migration notes explain the route.

🟠 Major · Update the TLS test assertions to the new primary domain. · PubSubHttpClientTest.php:151
tests/PubSubHttpClientTest.php:151
🎯 Functional Correctness | 🟠 Major | ⚡ Quick winUpdate the TLS test assertions to the new primary domain.
The docblocks of these tests now say requests go to
main.realtime.ably.net. The regex assertions still matchrest\.ably\.io. The default primary domain is nowmain.realtime.ably.net. The URL ishttps://main.realtime.ably.net:443/time. All three tests fail.Proposed fix
- $this->assertMatchesRegularExpression( '/^https:\/\/rest\.ably\.io/', $ably->http->lastUrl, 'Unexpected scheme/url mismatch' ); + $this->assertMatchesRegularExpression( '/^https:\/\/main\.realtime\.ably\.net/', $ably->http->lastUrl, 'Unexpected scheme/url mismatch' );Apply the same change at Line 165 with
http:and at Line 179 withhttps:.Also applies to: 165-165, 179-179

Bracket IPv6 literals when building request URLs.
Defaults::isHostname() accepts ::1, and ClientOptions preserves it as the primary domain. getHostUrl() then constructs https://::1:443, which is not a valid cURL IPv6 authority. Bracket the URL-only value without changing the stored primary domain.
Suggested fix
public function getHostUrl($host) {
+ if (filter_var($host, FILTER_VALIDATE_IP, FILTER_FLAG_IPV6) !== false) {
+ $host = '[' . $host . ']';
+ }
return ($this-> tls ? 'https://' : 'http://') . $host. ':' .$this->activePort();

Reject empty or non-string endpoint values before resolving the primary domain.
ClientOptions::$endpoint is documented as string|null, but the constructor accepts arbitrary option values and only replaces values that empty() considers empty. A whitespace-only endpoint and nonprod: therefore reach Defaults::getPrimaryDomain() and can produce invalid domains. A non-string value such as an array reaches strpos() and can raise a type error.
Validate the endpoint at the ClientOptions boundary. Reject non-string values and reject routing-policy values with an empty identifier. Preserve the existing default for an unset endpoint.

Make the `endpoint` client option (REC1, REC2) the only way to choose where the client connects, aligning with the other Ably SDKs' next major. The default primary domain moves from rest.ably.io to main.realtime.ably.net, with fallbacks main.[a-e].fallback.ably-realtime.com; `nonprod:[id]` resolves to the non-production cluster, and a hostname endpoint is used as given with no default fallbacks. - Remove the `environment` and `restHost` options and the legacy host and environment-fallback derivation - Rename ClientOptions::getPrimaryRestHost() to getPrimaryDomain() - Stop suppressing default fallbacks when port or tlsPort is set, following the spec - Run tests against ABLY_ENDPOINT (default nonprod:sandbox) instead of ABLY_ENV; cover routing-policy, nonprod, hostname and custom fallback resolution - Document the migration in UPDATING.md and CHANGELOG.md Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
