+# LLVM.jl release notes
+
+
+## In development: LLVM.jl v9.1
+
+The most important feature of this release is the addition of documentation, both in the
+form of function docstrings, and an extensive manual.
+
+As part of the documentation writing effort, many minor issues or areas for improvement were
+identified, resulting in a large amount of minor, but breaking changes. For all of those,
+deprecations are in place, so this release is not technically breaking. However, it is
+strongly recommended to update your code to the new APIs as soon as possible, which can be
+done by testing your code with `--depwarn=error`.
+
+Technically beaking changes:
+
+- Metadata values attached using the `metadata` function [now need to
+  be](https://github.com/maleadt/LLVM.jl/pull/476) a subtype of `MDNode`. This behavior
+  was already expected by LLVM, but only triggered a crash using an assertions build.
+- Creating a `ThreadSafeModule` from a `Module` [now
+  will](https://github.com/maleadt/LLVM.jl/pull/474) copy the source module into the active
+  thread-safe context. This is a behavioural change, but is unlikely to affect any users.
+  The previous behavior resulted in the wrong context being used, which could lead to
+  crashes.
+
+Minor changes:
+
+- Branch instruction predicate getters [have been
+  renamed](https://github.com/maleadt/LLVM.jl/pull/473) from `predicate_int` and
+  `predicate_float` to simply `predicate`. The old names are deprecated.
+- Conversion of a `MDString` to a Julia string [is now
+  implemented](https://github.com/maleadt/LLVM.jl/pull/470) using the `convert` method,
+  rather than the `string` method. The old method is deprecated.
+- The `delete!` and `unsafe_delete!` methods [have been
+  renamed](https://github.com/maleadt/LLVM.jl/pull/467) to `remove!` and `erase!` to more
+  closely match LLVM's terminology. The old names are deprecated.
+- Copy constructors [have been deprecated](https://github.com/maleadt/LLVM.jl/pull/466) in
+  favor of explicit `copy` methods.
+- Several publicly unused APIs that had been deprecated upstream, have been removed:
+  [`GlobalContext`](https://github.com/maleadt/LLVM.jl/pull/463),
+  [`ModuleProvider`](https://github.com/maleadt/LLVM.jl/pull/465),
+  [`PassRegistry`](https://github.com/maleadt/LLVM.jl/pull/461).
+
+New features:
+
+- A `lookup` function [has been added](https://github.com/maleadt/LLVM.jl/pull/458) to
+  enable extracting the address of a compiled function from an execution engine. This makes
+  it possible to simply `ccall` a compiled function without having to deal with
+  `GenericValue`s.
+
+
+## LLVM.jl v9.0
+
+Major changes:
+
+- The `OperandBundle` API [was changed](https://github.com/maleadt/LLVM.jl/pull/437) to the
+  upstream version, replacing `OperandBundleDef` and `OperandBundleUse` with
+  `OperandBundle`, renaming `tag_name` to `tag` and removing `tag_id`. No deprecations are
+  in place for this change.
+- The `SyncScope` API [was changed](https://github.com/maleadt/LLVM.jl/pull/443) to the
+  upstream version, switching from string-based synchronization scope names to a
+  `SyncScope` object, while adding `is_atomic` check and `syncscope`/`syncscope!` getters
+  and setters for atomic instructions. Deprecations are in place for the old API.
+
+New features:
+
+- Support for LLVM 18
+- An alias-analysis pipeline [can now be
+  specified](https://github.com/maleadt/LLVM.jl/pull/439) using the `NewPMAAManager` API.
+- API wrappers [now come with](https://github.com/maleadt/LLVM.jl/pull/448) docstrings.
+- Functions [have been added](https://github.com/maleadt/LLVM.jl/pull/447) to move between
+  blocks, instructions and functions without having to iterate using the parent.
+
+
+## LLVM.jl v8.1
+
+Minor changes:
+
+- Support for Julia versions below v1.10 has been dropped.
+
+New features:
+
+- A [memory checker](https://github.com/maleadt/LLVM.jl/pull/420) has been added. Toggling
+  the `memcheck` preference to `true` will enable LLVM.jl to detect missing disposes, use
+  after frees, etc.
+- Support for `atomic_rmw!` with synchronizatin scopes [has been
+  added](https://github.com/maleadt/LLVM.jl/pull/431)
+
+
+## LLVM.jl v8.0
+
+Major changes:
+
+- The NewPM wrappers [have been overhauled](https://github.com/maleadt/LLVM.jl/pull/416) to
+  be based on the upstream string-based interface, rather than maintaining various API
+  extensions to expose the pass manager internals. There are no deprecations in place for
+  this change.
+
+
+## LLVM.jl v7.2
+
+Minor changes:
+
+- Metadata APIs [have been extended](https://github.com/maleadt/LLVM.jl/pull/414) to all
+  value subtypes, making it possible to attach metadata to functions.
+
+
+## LLVM.jl v7.1
+
+Minor changes:
+
+- The NewPM internalize pass [has been
+  extended](https://github.com/maleadt/LLVM.jl/pull/409) to support a list of exported
+  symbols. This makes it possible to switch GPUCompiler.jl to the new pass manager.
+
+
+## LLVM.jl v7.0
+
+Major changes:
+
+- `LowerSIMDLoopPass` [was switched](https://github.com/maleadt/LLVM.jl/pull/398) to being a
+  loop pass on Julia v1.10. This may require having to use a different pass manager.
