v0.2.8

• Change error message when evaluating PossiblyNormalCompletion
• Added --omitInvariants option to prevent invariants from being included in generated code.
• Print out call stack in default error handler
• More simplifications
• Add missing check for invalid use of Map
• Simplify if conditions

v0.2.7

Basic expression simplification and refinement with path conditions. Various small improvements.

v0.2.6

Changed CLI options:

• Allow Prepack CLI to prepack multiple source files
• Disabling inlining of expressions by default; use --inlineExpressions option to activate this now optional feature.
• Disabling delaying of initialization code to residual functions; use --delayInitializations to activate this now optional feature.

Improvements to abstract reasoning:

• Support for certain abstraction uses of toString.

Improved ES6 support:

• Support for serialization symbol-based object properties

Many bug fixes, prepack performance and code generation improvements, including:

• Pure environment-facing statements are no longer emitted if produced value is not used

Work towards future features:

• Added a checker to determine if a set of residual functions do not have conflicting side effects when running right after global code; use internal additionalFunctions option (not yet exposed via CLI) to active this feature. This is the first step towards the bigger feature of prepacking certain residual functions.
