All notable changes to this project will be documented in this file. This project uses Semantic Versioning.

• #84: Added code coverage tracking and improved test coverage.

• #82: Added support for PDDL line comments.

• Added a PartialEq for Name that allows comparison with str and String directly.

• Renamed Problem::goal to Problem::goals to reflect the fact that it is iterable.
• If well-known names such as object or number are used for a Name, these values will be interned to a 'static str.

• The thiserror dependency is now only brought in with the parser crate feature.
• Use string interning to reduce the number of allocations required for Name types.

• Added TryInto<PreconditionGoalDefinition> for PreconditionGoalDefinitions to get the only element of the list if it is a one-element list, or None.
• TryInto implementations were added for CEffect to allow deconstruction into PEffect, ForallCEffect and WhenCEffect.
• Added the Parser::from_str method that performs a Parse::parse but discards the remaining unparsed text.

• The PrefConGD::And variant was removed and replaced with the PrefConGDs type.
• The Effect::All and Effect::Single variants were removed and the Effect type was changed to a struct wrapping a vector Effects.
• The CEffect variants were changed to wrap ForallCEffect and WhenCEffect types.
• The parser now uses nom-greedyerror and nom_locate to improve error handling.
• The Parser trait now takes an T: Into<Span<'a>> argument.
• All parser methods now take an T: Into<Span<'a>> argument.

• Fixed an issue where (and ...) conditional effects would be accidentally parsed into an atomic formula with predicate and.

• Added IntoIterator implementations for ConditionalEffect, DurationConstraint and Effect that flatten the Single and All variants into a single iterator. In all these cases, the (and ...) representation allows for a cardinality of zero, one or many, which makes x and (and x) identical.
• Added From<AtomicFormula<T>> for Literal<T>.

• The PreGD type was renamed to PreconditionGoalDefinition.
• The PreconditionGoalDefinition::And variant was removed and replaced with the PreconditionGoalDefinitions type.

• The nom dependency is now an implicit feature used by the parser crate feature.

• Added Parser trait.

• Made types module private and re-exported all types top-level.

• Minor usability adjustments such as added accessors for internal state of structs.

• 🎉 Initial release.
