v1.13.0rc0

v1.13.0 addresses several WDL 1.1 spec interoperability issues, with thanks to the reporting community members.

Because these changes bear small backwards-compatibility risks, we begin with release candidate v1.13.0rc0 that must be expressly requested with: pip install miniwdl==1.13.0rc0. Please report any issues or unexpected behaviors for investigation over the next few weeks.

Interoperability

• dedent task commands before eval/interpolation (#674 @adamnovak)
• allow float values for task runtime.cpu (#690 @adamnovak)
• round() "half up" instead of "to even" (#698 @stxue1)
• fix Array runtime typing issues (#699 #700 @stxue1 )
• allow trailing commas in meta arrays (#708 @adthrasher)
• fix ValueError reading empty JSON into Map (#726 @ahvigil)
• refactor typechecking for equatability & comparability (#736)
• allow non-typesafe read_json(...) within arrays and if-then-else branches (#740 @ahvigil)

Runner

• allow namespace prefix in task-only input JSON files (#693 @stxue1)
• fix cache of task with empty outputs (#715 @adamnovak)
• fix recognition of exponential notation in JSON/YAML run input files (#717 @sach244n)

Python WDL API

• Multi-line strings (development/1.2 feature) get first-class AST representation as WDL.Expr.MultiLineString, which is dedented upon evaluation (instead of during parsing into WDL.Expr.String).
• WDL.Type.* classes expose ty1.equatable(ty2) and ty1.comparable(ty2) operators, indicating whether it is valid to use the WDL == != or < <= > >= operators, respectively.
