  • GET '/rules' support for pagination and fuzzy search. #8472 ‼️ Note : The previous API only returns array: [RuleObj1,RuleObj2], after updating, it will become {"data": [RuleObj1,RuleObj2], "meta":{"count":2, "limit":100, "page":1}, which will carry the paging meta information.
  • Fix the issue that webhook leaks TCP connections. ehttpc#34, #8580

5.0.2

Announcement: EMQX team has decided to stop supporting relup for opensource edition. Going forward, it will be an enterprise-only feature.

Main reason: relup requires carefully crafted upgrade instructions from ALL previous versions.

For example, 4.3 is now at 4.3.16, we have 4.3.0->4.3.16, 4.3.1->4.3.16, ... 16 such upgrade paths in total to maintain. This had been the biggest obstacle for EMQX team to act agile enough in delivering enhancements and fixes.

Enhancements

Bug fixes

  • Fixed a typo in bin/emqx which affects MacOs release when trying to enable Erlang distribution over TLS #8398
  • Restricted shell was accidentally disabled in 5.0.1, it has been added back. #8396

5.0.1

5.0.1 is built on Erlang/OTP 24.2.1-1. Same as 5.0.0.

5.0.0 (like 4.4.x) had Erlang/OTP version number in the package name. This is because we wanted to release different flavor packages (on different Elixir/Erlang/OTP platforms).

However the long package names also causes confusion, as users may not know which to choose if there were more than one presented at the same time.

Going forward, (starting from 5.0.1), packages will be released in both default (short) and flavored (long) package names.

For example: emqx-5.0.1-otp24.2.1-1-ubuntu20.04-amd64.tar.gz, but only the default one is presented to the users: emqx-5.0.1-ubuntu20.04-amd64.tar.gz.

In case anyone wants to try a different flavor package, it can be downlowded from the public s3 bucket, for example: https://s3.us-west-2.amazonaws.com/packages.emqx/emqx-ce/v5.0.1/emqx-5.0.1-otp24.2.1-1-ubuntu20.04-arm64.tar.gz

Exceptions:

  • Windows package is always presented with short name (currently on Erlang/OTP 24.2.1).
  • Elixir package name is flavored with both Elixir and Erlang/OTP version numbers, for example: emqx-5.0.1-elixir1.13.4-otp24.2.1-1-ubuntu20.04-amd64.tar.gz

Enhancements

  • Added more TCP options for exhook (gRPC) connections. #8317

  • Provide authentication counter metrics #8352 #8375
  • Do not allow admin user self-deletion #8286
  • After restart, ensure to copy cluster-override.conf from the clustered node which has the greatest tnxid. #8333

Bug fixes

  • Fixed Erlang distribution over TLS #8309
  • Made possible to override authentication configs from environment variables #8323

  • Sync data/authz/acl.conf and data/certs from clustered nodes after a new node joins the cluster #8369
  • Ensure auto-retry of failed resources #8371
  • Fix the issue that the count of packets.connack.auth_error is inaccurate when the client uses a protocol version below MQTT v5.0 to access #8178
