10.6.3

April 20 2026

Fixed

• The retry limit was silently clamped to the policy default, configured intervals were ignored by delay calculators, and the async reconnection loop never checked the limit or advanced its counter — fix all three and add a maximum_reconnection_interval config option.

Modified

• seqn is not required by PubNub REST API, so remove PublishSequenceManager, all its subclasses, MAX_SEQUENCE, and seqn injection.
• Cover LinearDelay, ExponentialDelay, ReconnectionManager, ReconnectEffect, and HeartbeatDelayedEffect with deterministic assertions for default, custom, and edge cases.
