lang
Erlang is a general-purpose, concurrent, functional high-level programming language, and a garbage-collected runtime system. The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs.

Erlang/OTP does not follow Semantic Versioning. However, it does follow some
of its principles with a two to four parts version number, <Major>.<Minor>.<Patch>.<X>, where:
-
<Major>increments when there are major or incompatible changes, -
<Minor>increments when there are new features, -
<Patch>(optional) increments when there are pure bug fixes, -
<X>(optional) is a part used for partially ordered versions.
More information about the versioning scheme can be found in the Erlang/OTP documentation.
The release policy is not documented, but looking at the latest releases it seems that a new major version is released every year in May and supported for approximately 3 years.
According to Erlang/OTP’s support policy, bugs are in general only fixed on the latest release, and new features are introduced in the upcoming release. In practice, small improvements are regularly added to the latest release, and major bug and security fixes are backported to the supported previous releases.
More information is available on the Erlang website.
You should be running one of the supported release numbers listed above in the rightmost column.
