v1.9.0

Added

• Support Python 3.15.
• Add a py.typed marker.
• Support negation of relative existence queries in extended filter expressions (e.g. $[?(!@.field)]).

Fixed

• Ignore non-mapping values when updating named fields instead of raising TypeError (#104).

• Return no matches for negative array indices beyond the start of an array,
  matching the behavior of out-of-range positive indices (#203).

• Fix extended filter equality against an integer literal truncating float values,
  so [?(@.v = 0)] no longer matches an element with v = 0.6 (#227).

• update() with an in-place callback returning None no longer overwrites the field with None (#163)

• Fix an AttributeError that occurs when an Index instance is hashed. (#224)

• Index.find no longer raises KeyError when applied to a dict
  (e.g. $.*[0], where * matched a dict value).
  It now matches nothing, as the docstring promises. (#93)

• Fix extended parser handling of field names that start with true or false.

• Stop serializing Child paths with surrounding parentheses. (#215)

• Avoid mutating dictionaries while evaluating extended filter expressions.

• str() of an Index with comma-separated indices (e.g. [0,1]) no longer raises TypeError.

• Fix broken Slice serialization behavior.

  Previously, a slice like [0:] would serialize to [],
  and a slice like [::2] would serialize to [:2].

Removed

• Drop support for Python 3.10.
