[Unreleased]

[2.4.2] - 2024-01-18

Added

  • IPv6 support.
  • remove_member function to clean up member data.

[2.4.1] - 2023-09-28

Fixed

  • Log overflow when inner fibers weren't canceled.

[2.4.0] - 2021-07-12

Added

  • New option SUSPICIOUSNESS (default: true) allows to disable generation of rumors about suspected members. Also, membership won't produce any rumors unless myself is alive.

  • New option log_debug which can be easily overridden to control the verbosity level.

Fixed

  • Uncaught exception which prevented discovering non-decryptable members.

  • Avoid event duplication due to a bug.

  • Properly handle the internal option NUM_FAILURE_DETECTION_SUBGROUPS which controls the number of indirect pings.

Fixed

  • Enhance logging of getaddrinfo errors when DNS malfunctions.

[2.3.1] - 2020-11-18

  • Make the initialization error more informative.

[2.3.0] - 2020-11-17

Added

  • Allow reloading the code on the fly without status intervention.

Fixed

  • Make subscriptions garbage-collectible. Previously, fiber.cond objects obtained from membership.subscribe should have been unsubscribed manually, otherwise, they would never be GC'ed. And now they are.

[2.2.0] - 2019-10-22

Added

  • New field member.clock_delta, which indicates difference between remote and local clocks.

[2.1.4] - 2019-08-25

Fixed

[2.1.3] - 2019-08-01

Fixed

  • Leaving membership with encryption enabled. Due to the bug, other members reported 'dead' status instead of 'left'.

Added

  • Ldoc api documentation

Fixed
