0.13.37 - 2019-11-20
|
||||
--------------------
|
||||
|
||||
DAML Stdlib
|
||||
~~~~~~~~~~~
|
||||
|
||||
- Added the ``NumericScale`` typeclass, which improves the type inference for Numeric literals, and helps catch the creation of out-of-bound Numerics earlier in the compilation process.
|
||||
- ``fromAnyChoice`` and ``fromAnyContractKey`` now take
|
||||
the template type into account.
|
||||
|
||||
Navigator
|
||||
~~~~~~~~~
|
||||
|
||||
- Fixed a bug where Navigator becomes unresponsive if the ledger does not contain any DAML packages.
|
||||
|
||||
Ledger-API
|
||||
~~~~~~~~~~
|
||||
|
||||
- Add field ``gen_map`` in Protobuf definition for ledger
|
||||
api values. This field is used to support generic maps, an new
|
||||
feature currently in development. See issue
|
||||
https://github.com/digital-asset/daml/pull/3356 for more details
|
||||
about generic maps.
|
||||
The Ledger API will send no messages where this field is set, when
|
||||
using a stable version of DAML-LF. However the addition of this
|
||||
field may cause pattern-matching exhaustive warnings in the code of
|
||||
ledger API clients. Those warnings can be safely ignored until
|
||||
GenMap is made stable in an upcoming version of DAML-LF.
|
||||
|
||||
Extractor
|
||||
~~~~~~~~~
|
||||
|
||||
- The app can now work against a Ledger API server that requires client authentication. See `issue #3157 <https://github.com/digital-asset/daml/issues/3157>`__.
|
||||
|
||||
DAML Compiler
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
- **Breaking** The default DAML-LF version is now 1.7. You can still
|
||||
produce DAML-LF 1.6 by passing ``--target=1.6`` to ``daml
|
||||
build``. This removes the ``Decimal`` type in favor of a ``Numeric
|
||||
s`` type with a flexible scale. ``Decimal`` is now a synonym for
|
||||
``Numeric 10``. If you get errors about ambigous literals, you might
|
||||
need to add a type annotation, e.g., replace ``1.0`` by ``(1.0 : Decimal)``.
|
||||
|
||||
JSON API - Experimental
|
||||
~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- CLI configuration to enable serving static content as part of the JSON API daemon:
|
||||
``--static-content "directory=/full/path,prefix=static"``
|
||||
This configuration is NOT recommended for production deployment. See issue #2782.
|
||||
- The database schema has changed; if using
|
||||
``--query-store-jdbc-config``, you must rebuild the database by adding
|
||||
``,createSchema=true``.
|
||||
See `issue #3461 <https://github.com/digital-asset/daml/pull/3461>`_.
|
||||
- Terminate process immediately after creating schema. See issue #3386.
|
||||
|
||||
DAML Triggers - Experimental
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- ``emitCommands`` now accepts an additional argument
|
||||
that allows you to mark contracts as pending. Those contracts will
|
||||
be automatically filtered from the result of ``getContracts`` until
|
||||
we receive the corresponding completion/transaction.
|
||||
|
||||
DAML Script - Experimental
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- This release contains a first version of an experimental DAML script
|
||||
feature that provides a scenario-like API that is run against an actual ledger.
