1.1.9.2 - 20151027

• [name analysis] Name analysis & dependency analysis more fine-grained, required by local instances.

1.1.9.0 - 20150430

1.1.8.8 - 20150301

• unused version

1.1.8.7 - 20150219

• [compiler driver] Refactoring: top level compiler driver functions now are typed as monad transformer, requiring adapted uhc-utils>=0.1.5.0.
• [corerun] More primitives implemented.
• [corerun] CoreRun files can be serialized, now also generated by default (enabling direct running these).

1.1.8.6

• [build] fix for uhc-light-1.1.8.5 package build failure.

1.1.8.5

• [uhcr] Can run Core directly, on the fly compilation to CoreRun.
• [corerun] Generic (un)marshalling for CoreRun FFI.
• [core, api] Export of data types, new Core AST/API to express this.
• [corerun] Better fix for CoreRun access of globals during global init.

1.1.8.4 - 20150120

1.1.8.1 - 20141217

• [build] Separate target in makefiles for 'ehcr', with trace option.
• [corerun, api] CoreRun API extended to be usable by CCO lab exercise.

1.1.8.0 - 20141212

• [corerun, api] CoreRun has its own API.
• [core, api] Interface to Core main changed in that the state parameter is already passed explicitly (not implicitly added during later compiler pipeline stages), influences the api.
• [corerun] Cleaned up CoreRun AST, spec of the operational semantics under development (separate outside src/doc tree).

• [corerun] Parser for CoreRun.

1.1.7.4 - 20141203
