1.3 KiB

  • Compile ESM package that can be used directly in the browser as actioncable.esm.js.

    DHH

  • Move action_cable.js to actioncable.js to match naming convention used for other Rails frameworks, and use JS console to communicate the deprecation.

    DHH

  • Stop transpiling the UMD package generated as actioncable.js and drop the IE11 testing that relied on that.

    DHH

  • Truncate broadcast logging messages.

    J Smith

  • OpenSSL constants are now used for Digest computations.

    Dirkjan Bussink

  • The Action Cable client now includes safeguards to prevent a "thundering herd" of client reconnects after server connectivity loss:

    • The client will wait a random amount between 1x and 3x of the stale threshold after the server's last ping before making the first reconnection attempt.
    • Subsequent reconnection attempts now use exponential backoff instead of logarithmic backoff. To allow the delay between reconnection attempts to increase slowly at first, the default exponentiation base is < 2.
    • Random jitter is applied to each delay between reconnection attempts.
