v0.7.12

Allowing return from expression if (#1080)

Enhancements:

• Allow a return statement in final position in an if expression (see #1060)

Notes:

• Return from a statement if short-circuits the expression and returns from the enclosing function

v0.7.11

String interpolation (#1078)

Enhancements:

• Add initial support for string interpolation (see #1071)

Bugs fixed:

• Can't use ref struct types (partial fix only #1077)

v0.7.10

Fix error cascade when undefined type used as formal argument (#1076)

Bugs fixed:

• Formal arguments of undefined type can case a cascade of spurious errors (closes #1075)

Technical:

• Bump compiler tool to latest
• Bump integration test runner tool to latest
• Bump runtime library to latest
• Replace instances of deprecated | .has(...) with | .any(...)

v0.7.9

If expressions improvements (#1070)

Enhancements:

• Infer if expression type from context, where initializing an explicitly typed variable or being returned from a function
• Fewer redundant error messages when if statements and expressions are incomplete
• Support throw statement as a value in an if expression

Bugs fixed:

• No error reported when an if expression had no else branch
• Nested if expressions generated incorrect IL

Technical:

• Report elapsed time in bootstrap script
• Add a very simple mechanism for representing a block of IL instructions as an IL value
• Improve indentation of control flow IL assembly and add comments

See #1060

v0.7.8

Experimental support for if expressions (#1069)

Enhancements:

• Add experimental support for if expressions (see #1060)
• Semicolons are now a statement separator rather than a terminator (see #1060).
• Allow parentheses in type expressions, which can be used to remove ambiguity (for example (int -> int) -> int is different to (int -> (int -> int))

Bugs fixed:

• Fix issue with explicit return types for expression bodied generic functions and methods (closes #1067)

Technical:

• Remove some debug output
• Underlying support for statements having values

Notes:

• If expressions could generate IL that doesn't assemble, fails to load, or executes incorrectly: use at your own risk
• Semicolons continue to be accepted at the end of statement lists, but they're no longer required. Unnecessary semicolons are not an error
• Semicolons are still a terminator for global definitions and definitions within classes, structs and traits

v0.7.7

Warn on unchecked type constraints (#1066)

Bugs fixed:

• Give a warning when referencing generic types or functions that have constraints on their type arguments (closes #1065)

Notes:

• This does not prevent generation of potentially incorrect and unsafe IL. It simply issues a warning where types or functions with type constraints are referenced. See #115 for details.

v0.7.6

Fix type check issues (#1064)

Bugs fixed:

• Fix issue where null was wrongly treated as assignment compatible with value types (closes #1061)
• Fix issue where different generic type arguments were sometimes wrongly treated as assignment compatible with each other (closes #1062)
• Fix issue where null was wrongly treated as assignment compatible with generic type arguments (closes #1063)

Technical:

• Remove workarounds for recently fixed anonymous function argument type inference issue
• Add integration tests asserting generic type arguments are compatible with object
• Make error messages for failed type inference consistent with each other

v0.7.5

Fix generic function argument inference issue (#1059)

Bugs fixed:

• Fix problem where argument types of function literals were not always correctly infered from context (closes #778)

Technical:

• Add functions for managing debug output

v0.7.4

Add runtime library compatibility tests (#1058)

Technical:

• Add integration tests to check compiler compatibility with the runtime library
• Remove the unused none keyword
• Remove debug output when hiding ambiguous methods in reflected types
• Fix broken VSCode tasks for integration tests on Windows
• Update .gitattributes to strip \r on Windows
• Bump ghul-test tool to get updated runtime for integration tests

v0.7.3

Fix spurious ambiguous call error (#1057)

Bugs fixed:

• Fix issue where "call is ambiguous" could be reported attempting to call certain methods (closes #1056)

Technical:

• Add an additional kind of test ('project tests') that are built using MSBuild and can reference other projects and packages.
