DAML Assistant

• Fix VSCode path for use if not already in PATH on mac
• BREAKING: remove --replace=newer option.

DAML Studio

• Fix a bug where the extension seemed to disappear every other time VS Code was opened.
• DAML Studio now displays a “Processing” indicator on the bottom left while the IDE is doing work in the background.

Sandbox

• Fixing an issue around handling passTime in scenario loader See https://github.com/digital-asset/daml/issues/1953.
• Remembering already loaded packages after reset See https://github.com/digital-asset/daml/issues/1979.

DAML-LF

• Release version 1.6. This versions provides:

  • enum types. See issue https://github.com/digital-asset/daml/issues/105 and DAML-LF 1 specification for more details.

  • new builtins for (un)packing strings. See issue https://github.com/digital-asset/daml/issues/16.

  • intern package IDs. See issue https://github.com/digital-asset/daml/pull/1614.

  • BREAKING CHANGE Restrict contract key lookups. In short, when looking up or fetching a key, the transaction submitter must be one of the key maintainers. The restriction was done in the DAML-LF development version (1.dev) until now. See issue https://github.com/digital-asset/daml/issues/1866. This change is breaking, since this release makes DAML-LF 1.6 the default compiler output.

DAML Compiler

• Add support for DAML-LF 1.6. In particular:

  • BREAKING CHANGE Add support for enum types. DAML variant types that look like enumerations (i.e., those variants without type parameters and without arguments) are compiled to the new DAML-LF enum type when DAML-LF 1.6 target is selected. For instance the daml type declaration of the form:

    data Color = Red | Green | Blue
    

    will produce a DAML-LF enum type instead of DAML-LF variant type. This change is breaking, since this release makes DAML-LF 1.6 the default compiler output.

  • Add DA.Text.toCodePoints and DA.Text.fromCodePoints primitives to (un)pack strings.

  • Add support for DAML-LF intern package IDs.

• BREAKING CHANGE Make DAML-LF 1.6 the default output. This change activates the support of enum type describes above, and the restriction about contract key lookup described in the DAML-LF section

• BREAKING CHANGE Drop support for DAML-LF 1.5. Compiling to DAML-LF 1.6 requires some changes regarding enum types to applications using the Ledger API, see above. (The ledger server still supports DAML-LF 1.5.)

Ledger API

• Add support for enum types. Simple DAML variant types will be mapped to DAML-LF enum types when using a DAML-LF 1.6 archive. Ledger API Value Protobuf provides the new Enum message. This message must be used to communicate this new data type through the API.

Java Codegen

• Add support for enum types. enum types are mapped to standard java enum. See Generate Java code from DAML for more details.

Scala Codegen

• Add support for enum types.

Navigator

• Add support for enum types.

Extractor

• Add support for enum types.
