,reload; see ,help for a full list--no-compiler-sandbox did not apply in import-macrosmacrodebug fail to print correctly--no-sandbox-compiler to --no-compiler-sandbox in help/docs: when used with methods that are not valid Lua namesThis release introduces the plugin system as well as starting to sandbox the compiler environment for safer code loading. Nothing is blocked yet, but it emits warnings when macros use functionality that is not considered safe; future versions will prevent this.
@list? and sym? in compiler API.--lua CLI flag for specifying a custom Lua command/executable. (#324)This release features a version of the Fennel compiler that is self-hosted and written entirely in Fennel!

with-open macro for automating closing file handles, etc.

--compile-binary command (#281)This release adds support for Lua 5.3's bitwise operators as well as a
new way of importing macro modules. It also adds pick-values and
pick-args for a little more flexibility around function args and
return values. The compiler now tries to emit friendlier errors that
suggest fixes for problems.

The first real release sees the addition of several "creature comfort" improvements such as comments, iterator support, line number tracking, accidental global protection, pretty printing, and repl locals. It also introduces the name "Fennel".
