v0.11

• Add scm.import-from-module function to import bindings from Scheme modules into Shen's environment.

v0.10.1

• Fix for print vectors so that no symbol disambiguation is needed.

v0.10

• Update for Shen 17.
• Better handling of paths and current directory.
• Scheme functions are now available with the scm. prefix.
• Replaced $native form with scm. form that takes a string of Scheme code that will not be processed.
• Support for running scripts from the command line without launching a REPL.
• Fixed optimised version of shen.grammar_symbol? (was broken for namespaced symbols)
• Removed overwrites for macroexpand and walk.
• Removed unused segvar? overwrite.
• Removed internal function registry and support for symbol disambiguation on function application.
• Explicit BSD licence everywhere.

v0.9

• Optimise out unnecessary wrapper lambdas.
• Optimise equality checks.
• Slightly better trap-error and error messages.
• Function overwrites are now handled when precompiling instead of startup.
• Internal code reorganization and simplification.

v0.8

• Works with Shen 16.
• Updated for chibi-scheme 0.7.
• Fixes issue with functions that partially apply themselves.
• Add optimized 'shen.pvar?' overwrite. Makes prolog and typechecking considerably faster.
• Add a fast-path for the common case of trap-error
• Shen sources are precompiled now instead of being compiled on the fly on startup, this provides better startup times.

v0.7

• Works with Shen 15.

v0.6

• Works with Shen 13.
• Update the 'open' procedure.
• Add 'write-byte' procedure.
• Remove 'pr' procedure.

v0.5

• Works with Shen 9
• Support for $native expressions.

v0.4

• Switched to curry-on-demand strategy for partial function applications. This improves performance considerably.

v0.3

• Improved performance and compatibility. Cleanup some dead code. Fixes
• Overrides are now done after loading the file that defines that function. This improves load time and memory usage by using the improved versions when still loading Shen.
• Added new overrides (macroexpand, shen-walk, hash, shen-digit-byte?, shen-byte->digit, symbol?, not, shen-segvar?, shen-grammar_symbol?.
• Better '=' function, with fast-path for references that are 'eq?' and vector compare without converting vectors to lists first.
• Removed safe symbol conversions, with a custom reader they are not needed.
• A much improved method of symbol->function resolution which uses a hash table instead of eval.
• Fix default fill value for absvectors (was 'fail!' when it should have been 'shen-fail!')
• Inline compares to '(fail)'.
