0.29.2 - 2022-09-26

Features

• Add Option.tla module providing support for option types (see #2097).

Bug fixes

• Fix missing support for single-line comments inside of type annotations (see #2162)

v0.29.1

0.29.1 - 2022-09-12

Bug fixes

• Report an error, when --max-error > 1 and no --view is provided, see #2144

v0.29.0

0.29.0 - 2022-09-06

Breaking changes

• Invalid configuration keys found in configuration sources (e.g., apalache.cfg files) will now produce a configuration error on load (see #2125).
• The structure of the apalache.cfg has changed. All configuration keys that were previously supported have been moved under the common key. You can update your config files by prefixing each key from the previous versions with commong.key-name. For an example config file, see https://apalache.informal.systems/docs/apalache/config.html#file-format-and-supported-parameters. See #2065.
• Introduce --features=no-rows for the old record syntax and switch to --features=rows by default

Features

• The application configuration is now dumped into the run-dir when the --debug flag is supplied (see #2134).
• All CLI parameters can now be configured via apalache.cfg files. See #2065 and documentation to follow.
• From now on, the type checker reports an error, when the inferred type is more specific than the annotated type, see #2109.
• The options --init and --temporal can now be given lists of names separated by commas, enabling users to check multiple invariants and temporal properties via the CLI (see #2074).
