RabbitMQ 3.8.7

RabbitMQ 3.8.7 is a maintenance release that patches
a security vulnerability.

RabbitMQ Core team would like to thank Ofir Hamam and Tomer Hadad at Ernst & Young's Hacktics Advanced Security Center
for researching and responsibly disclosing the vulnerability addressed in this release.

Erlang/OTP Compatibility Notes

This release requires Erlang/OTP 21.3 or later.
22.3 or 23.0 releases are recommended.

Provisioning Latest Erlang Releases explains
what package repositories and tools can be used to provision latest patch versions of Erlang 22.3.x.

Upgrade Doc Guides and Change Log

See 3.8.0 release notes upgrade and
compatibility notes first if upgrading from an earlier release.

See the Upgrading guide for general documentation on upgrades and
RabbitMQ change log for release notes of other releases.

Upgrading to Erlang 21.x or Later Versions

When upgrading to this release from 3.7.6 or an older version, extra care has to be taken.

Since CLI tools from RabbitMQ releases older than 3.7.7 will fail on Erlang 21 or later,
RabbitMQ must be upgraded at the same time as Erlang.

Alternatively the node can be upgraded to 3.7.18 first, then Erlang 22.x or 23.x, then RabbitMQ to most recent
3.8.x release.
