v0.13.20

Documentation

• Added platform-independent tips for testing

DAML Compiler

• Some issues that caused damlc test to crash on shutdown have been fixed.
• The DAML compiler was accidentally compiled without
  optimizations on Windows. This has been fixed which should improve
  the performance of damlc and daml studio on Windows.
• damlc build should no longer leak file handles so
  ulimit workarounds should no longer be necessary.
• Allow more contexts in generic templates. Specifically, template constraints can
  have arguments besides type variables, if the FlexibleContexts extension is enabled.

DAML-LF

• Breaking Rename NUMERIC back to DECIMAL in Protobuf definition.

DAML Studio

• damlc ide now also accepts --ghc-option arguments like damlc build
  so damlc ide --ghc-option -W launches the IDE with more warnings.
• The VSCode extension now has a configuration field for
  passing extra arguments to damlc ide.

DAML Integration Kit

• Participant State API and kvutils was extended with support for
  changing the ledger configuration. See changelog in respective package.scala files.

Sandbox

• Fixed a bug that caused the reset service to hang for 10
  seconds. See issue
  #2549.

Java Bindings

• The Java Codegen now supports parametrized ContractIds. See
  #2258.

DAML Standard Library

• Add stripInfix function to DA.List.
