Added

• pslua is now a first-class Spago backend. With
  workspace.backend.cmd: pslua in spago.yaml, spago build links the
  project to Lua, and a new --run <Module>.<entry> flag lets spago run and
  spago test compile an entry point, execute it with lua, and forward the
  interpreter's exit code (#117).
• Projects consume the published Lua package set through
  workspace.packageSet.url in spago.yaml: the PureScript Registry baseline
  with the Lua FFI forks overlaid.

Changed

• Migrated the toolchain to the current Spago (spago.yaml + spago.lock and
  the PureScript Registry), replacing the Dhall-based configuration (#55).
• Deeply nested Effect/ST do-blocks (magic-do) and other deep monadic
  spines are flattened so the generated Lua stays under the interpreter's
  syntactic nesting limit (#46, #104, #108).
• The Nix toolchain moved to purescript-overlay for a pinned purs
  0.15.16 and Spago 1.0.4 (#54).

Fixed

• De Bruijn indices are lowered correctly when a binder is removed, closing a
  class of silent miscompilations (#56).
• Eta reduction no longer rewrites programs unsoundly (#32); shift,
  substitute, and free-reference counting now respect sequential Let
  scoping (#37).
• Array-literal pattern binders read 1-based Lua indices instead of 0-based
  (#49).
• Char literals are escaped correctly, and table literals are parenthesised
  before they are indexed.
• The parent directory of --lua-output-file is created when it is missing
  (#61).

What's Changed

• Unused foreign imports are eliminated;
• All bindings are stored in a local variable M;

What's Changed

• Added missing support for the polymorphic record updates.
• Fixed name shadowing in #5

Alpha software is not thoroughly tested by the developer before it is released to customers. Alpha software may contain serious errors, and any resulting instability could cause crashes or data loss. Alpha software may not contain all of the features that are planned for the final version.
