Glasgow Haskell Compiler (GHC)
lang
Haskell is a general-purpose, statically-typed, purely functional programming language with type inference and lazy evaluation. The Glasgow Haskell Compiler (GHC) is a state-of-the-art optimizing compiler for Haskell. It includes an interactive REPL, several profilers, alternative codegen backends, and supports x86, AArch64, PowerPC, s390x, RiscV, WASM architectures.

Version support policy of GHC is defined informally, as a working convention that can be found documented on GHC wiki.
Terminology
Because GHC is a bootstrapping compiler (meaning, it is written mostly in Haskell and compiles itself), there’re versioning considerations not quite covered with SemVer.
GHC defines:
-
Major release -
x.y.1whereyis even. -
Minor release -
x.y.zwhereyis even andz ≥ 2.
The case x.y.z with y odd is reserved for development purposes. These versions are termed
snapshots and are never announced for general availability.
Release policies
-
Minor releases generally do not introduce new interfaces, compiler feature additions neither removals, nor major updates in libraries shipped with compiler. They only fix bugs or performance issues in the previous release on that branch.
-
Target platforms are segregated into tiers 1, 2, and 3; and releases are gated on being in working condition on all Tier 1 platforms. Every effort is made to fix bugs in Tier 2/3 platforms, but those are not treated as release blockers.
-
Source distributions are provided to distribution packagers a week in advance, before official binaries release is announced.
-
Two-release policy. Every release of GHC must be bootstrappable with the most recent minor release of the two most-recent major releases of GHC.
Release schedule
Major releases are made twice a year.
Minor releases are made throughout the year, with no fixed schedule.
Every release is preceded by one or more release candidates, announced on GHC mailing lists.
More information is available on the Glasgow Haskell Compiler (GHC) website.
You should be running one of the supported release numbers listed above in the rightmost column.
