Bugfix: Incorrect rendering of case clauses (#155). Thanks to Dave Gurnell for the report and fix.

New features including Scheme interoperability and runtime enhancements, Parenthetical JavaScript, and Harmony extensions.

• Changed runtime representation to interoperate with Scheme (notably booleans and procedures).
• Experimental Harmony features: tail-recursive block literals and @tt{do}-expressions.
• Continuation marks via a global Trace constructor.
• Improvements to internal representation of objects.
• New Name constructor and support for Name objects as property names.
• Parenthetical JavaScript: renewed support for S-expression syntax, now with improved syntax and support for source-location tracking.

• Implemented Array library. See issue #106.
• Implemented other miscellaneous standard libraries.
• Fixed a bug with treating primitives as objects. See issue #107.
• Fixed some prototype chain relationships in the standard library objects.
• Implemented a module language, allowing interoperability with Scheme modules.See issue #112.
• Implemented a #lang reader, enabling use with the Module language; try it out with #lang planet dherman/javascript. See issue #108.
• Implemented import and export declarations.
• Major reimplementation of variable binding.
• Correct implementation of eval that has access to the lexical environment.
• API changes in eval.ss, parse.ss, and compile.ss.

Major bugfix release:

• Significant re-implementation of internal environment structure. See issue #97.
• Fixed a bug in lookup of non-string property names.
• Fixed scoping semantics of function locals.
• Implemented eval, with proper inheritance of the environment and variable object (10.1.3). See issues #50, #51, and #97.
• Mutating with-bound variables now persists correctly. See issue #100.
• Fixed bugs in the implementation of variable assignment in dynamic code (i.e., code under with or eval.
• Indirect eval now raises a runtime exception when called.

Bugfix:

• Fixed precedence rules for pretty-printing (thanks to Dave Gurnell). See issue #96.

Bugfixes:

• Fixed a compilation error in test module.
• The arguments array wasn't being properly initialized in functions. See issue #94.

• The arguments array wasn't being properly initialized in functions. See issue #94.

Bugfixes including some new exports:

• Exported some internals from print.ss. See issue #82.
• Exported the utilities for an S-expression representation of JavaScript. See issue #90.
• Made AST structure types #:prefab. See issue #91.
• Exported config.ss and ast.ss from main.ss. See issue #92.
• Implemented a generic Term=? predicate. See issue #93.

Minor bugfixes:

• Fixed a precedence bug in pretty-printer. See issue #8.
• Deleted accidental duplicate module (private/syntax/print).

Several minor bugfixes:

• All AST struct types are #:transparent now. See issue #83.
• Sexp syntax faults on multiple var-declarations in for-in statements. See issue #89.

Several compatible updates:

• Fixed some broken contracts in ast.ss.
• Implemented let-declarations in the head of for-statements. See issue #55.
• Bugfix: compiler couldn't handle empty variable initializers.

Several compatible updates:

• Test cases are all now running and passing.
• Bugfix: the compiler was missing a crucial export (object-table).
• Bugfix: pseudo-parameter/c is fixed in parameter.plt 1:3, so config.ss should now work.

Completely revamped for PLT v4.x.

Completely revamped for PLT v4.x.

• Updated color preferences according to http://list.cs.brown.edu/pipermail/plt-scheme/2007-April/017369.html
• Added stubs for new methods in drscheme:language:language<%>

Corrected a broken contract (vars should be variables) that failed to compile.
