Versioning

Red is versioned as major.minor.micro

While this is very similar to SemVer, we have our own set of guarantees.

Major versions are for project wide rewrites and are not expected in the foreseeable future.

End-user Guarantees

Red provides support for wide variety of operating systems.

Support for an entire operating system (including support for any single architecture on that system) may only be dropped in a minor or major version bump.

Red will continue to, at the very least, support current latest stable version of each operating system + architecture that were supported by previous micro versions.

In addition to that, we strive (but do not guarantee) to provide support for all versions that are currently supported by operating system’s developers per the table below. We generally drop support for no longer supported OS versions as soon as they reached their end-of-life date.

Note

We recommend to always use the latest OS version supported by Red.

Tip

The meaning of architecture names:

  • x86-64 (also known as amd64) refers to computers running a 64-bit version of the operating system on standard Intel and AMD 64-bit processors supporting x86-64-v2 instruction set (post-2008 Intel processors and post-2011 AMD processors).

  • aarch64 (also known as arm64) refers to computers running an ARM 64-bit version of the operating system on 64-bit ARM processors (ARMv8-A and ARMv9-A) such as Apple M1 devices or Raspberry Pi computers (Raspberry Pi 3B and above, excluding Pi Zero (W/WH) model).

  • armv7l (also known as armhf) refers to computers running an ARMv7 version of the operating system on 32-bit or 64-bit ARM processors (ARMv7-A, ARMv8-A, ARMv9-A) such as Raspberry Pi computers (2B and above, excluding Pi Zero (W/WH) model).

Developer Guarantees

Any name (function, class, attribute) listed in the __all__ attribute of the redbot module (excluding its submodules), redbot.core package, or any of its public submodules (modules that do not start with “_”) is considered a public API and should not break without notice.

Methods of public classes are considered public if they do not start with “_” or are dunder methods (e.g. method() and __getattr__() are public but _method() isn’t).

Any other name (function, class, attribute) in the redbot package is considered private, even if it doesn’t start with “_”. Lack of __all__ in the module means that all of its names are considered private APIs.

Anything in the redbot.cogs and redbot.vendored modules or any of their submodules is specifically excluded from being guaranteed.

Method names and names of attributes of classes, functions, extensions, and modules provided by or provided to the bot should not begin with red_ or be of the form __red_*__ except as documented. This allows us to add certain optional features non-breakingly without a name conflict.

Any RPC method exposed by Red may break without notice.

If you would like something in here to be guaranteed, open an issue making a case for it to be moved.

Exclusions

Any exclusion from these guarantees should be noted in the documentation of the affected attribute, function, class, or method. The term “provisional” may be used in documentation to note such exclusions.

Breaking Change Notices

Breaking changes in Red will be noted in the changelog with a special section.

Breaking changes may only occur on a minor or major version bump.

A change not covered by our guarantees may not be considered breaking for these purposes, while still being documented as a breaking change in internal documentation for the purposes of other internal APIs.
