This is the draft release notes for 0.19.0, scheduled to be released around 2022-07-01.

Breaking changes

Deprecated features

Deprecated features will be removed in 0.20.0.

The following deprecated features trigger a warning whenever the code is parsed and compiled, even if it is not executed:

  • The float64 command is now deprecated. Use num for constructing a typed number, or inexact-num for constructing an inexact number.

    The documentation has advertised it as deprecated since the 0.16.0 release, but deprecation warnings were never added.

Notable bugfixes

  • Temporary assignment on an unset environment variables no longer leave it set to an empty string (#1448).

Notable new features

  • A new inexact-num converts its argument to an inexact number.

    It is functionally identical to the now deprecated float64 command since the Go float64 type is the only underlying inexact number type for now. Its behavior may change in future if there are more underlying types for inexact numbers.

  • A new type of interactive abbreviation: edit:command-abbr (#1472).
