v1.1.0

Changed

• A baseURL whose path has no trailing slash, such as https://proxy.example.com/configdirector,
  now keeps that path when the SDK builds its endpoints. It used to resolve relative to the parent,
  dropping the last path component.
• In .polling mode, a transient failure on the first fetch of initialize(context:) or
  updateContext(_:) no longer returns early with an error. The context is applied, polling
  continues on the interval, and the call waits for the first successful poll up to the timeout,
  the way .streaming mode already behaved. A .oneTime client, which never retries, still
  reports the failure and keeps the previous context.
• ConsoleLogger writes debug messages as private, since they carry config values. They are shown
  in full while a debugger is attached and redacted from the unified log otherwise. Warnings and
  errors are still public.
• Reconnection delays in .streaming mode are spread out with jitter, and a connection that opens
  but delivers nothing no longer resets the backoff.

Fixed

• A values(for:default:) stream now falls back to its default when a full config update no
  longer carries its config. It used to keep yielding the last value it had seen.
• Passing .infinity as timeout or pollingInterval no longer traps.
• updateContext(_:) calls that overlap, or that race with the reconnection performed when the
  app returns to the foreground, now apply in the order they were made. The last one made is the
  one that wins.
• .ready is no longer published before the new context is in effect when config state arrives
  on the heels of the connection opening.
• In .polling mode, an updateContext(_:) after an unrecoverable error now logs that error
  again instead of claiming the client will keep retrying, and the network is left alone when
  pauseNetwork() or close() is called while a connection attempt is in flight.
• The Last-Event-ID header is omitted after the server resets the event id to empty, as the
  server-sent events specification requires.
• A rejected response's body is cut to 200 characters in the error message.
• Telemetry no longer attributes an evaluation to the context it was not made against. Reading a
  config immediately after updateContext(_:) returned could be reported in the batch belonging to
  the previous context, because the collector was told about the new context in a detached task
  that had not necessarily run yet.

v1.0.0

Added

• ConfigDirectorClient, evaluating configs against a ConfigDirectorContext of id, name,
  traits and isAnonymous. updateContext(_:) re-evaluates every config against a new identity,
  keeping the previous one in effect until the reconnection succeeds or times out.
• Synchronous value(for:default:), safe to call from a SwiftUI body. Bool, String, Int and
  Double are supported, and any type can be read from a config by conforming to ConfigValue.
• value(for:as:default:), decoding a JSON config into any Decodable type.
• values(for:default:), an AsyncStream that yields the current value on subscription and then
  each change, without re-emitting a value that did not change.
• Three connection modes: .streaming over server-sent events, .polling on an interval, and
  .oneTime. Streaming reconnects on its own with a backoff, and stops on an unrecoverable status.
• Telemetry that aggregates config evaluations and reports them off the caller's thread, so
  evaluating a config never waits on the network.
• pausesWhileBackgrounded, dropping the connection while the app is backgrounded and restoring it
  on return, plus pauseNetwork() and resumeNetwork() to drive that manually.
• events and evaluations streams, publishing client lifecycle changes and every individual
  config evaluation.
• ConfigDirectorLogger, with a ConsoleLogger writing to the unified logging system under the
  com.configdirector.sdk subsystem.
• Support for iOS 15, iPadOS 15, macOS 12, tvOS 15 and watchOS 8, built in Swift 6 language mode
  under strict concurrency, with every public type Sendable.
