0.18.0

• Eliminated the build-time dependency on LLVM by putting the raw Rust bindings in source, instead of generating them at build time. This would also make builds faster.

0.17.0

• Added OnceGlobalRef, which eases the initialization of static references to long-lived Lisp values.
  • Added use_symbols!, which enables module code to use Lisp symbols without repeatedly interning them.
  • Added define_errors! and Env::signal to simplify the process of defining and signaling custom Lisp errors.
• Raised the minimum supported Rust version to 1.45.
• Added ResultExt::or_signal to make it more convenient to convert a Rust error into a Lisp error.
• Remove ResultExt::unwrap_or_propagate.

0.16.2

• Fixed compilation on aarch64-apple-darwin (Apple Silicon).

0.16.1

This was an incorrectly released version that is the same with 0.16.0.

0.16.0

• Replaced failure with anyhow and thiserror. Re-exported anyhow as emacs::error::anyhow.

0.15.1

• Fixed compilation errors on new versions of syn, which removed the export module.

0.15.0

• Disabled the workaround for Emacs's GC bug #31238 if possible (i.e. in Emacs 27+, where the bug was fixed). This should speed up module code in newer Emacs versions.

0.14.1

• Fixed proc macro's hygiene issues, for compatibility with Rust 1.47. Example: emacs-tree-sitter fails to compile.
  For details, see Rust's release note and PR that introduced this change.

0.14.0

• Reworked Vector, making it iterable.
• Changed Env::vector to return a Value.
• Added call_unprotected variants to Value::call, Env::call, GlobalRef::call, to enable certain optimizations.

0.13.0

• Added GlobalRef, which allows keeping Lisp values around without an Env.
• Reduced indirection when calling common built-in subroutines through Env.
• Removed module_init!, export_functions!, and their aliases.
• Replaced lazy_static dependency with once_cell.
• Fixed memory leaks caused by the memory safety fix for #2.
