Added

• Nested hashes will now warn for duplicated keys, as in: { foo: 1, **{ foo: 2 } }.
• Prism::ReturnNode now has a flag on it to indicate if it is redundant.
• Prism::Location#slice_lines and Prism::Node#slice_lines are now provided to slice the source code of a node including the content before the node on the same line that it starts on and the content after the node on the same line that it ends on.
• Symbols with invalid byte sequences now give errors.
• You can now pass "3.3.1" to the version: parameter on all Prism.* APIs.
• Prism::Source#lines, Prism::Location#source_lines, Prism::Node#source_lines, and Prism::Node#script_lines are now provided, which will all return the source code of the source as an array of strings.
• Prism::ASCIISource is now provided, which is a subclass of Prism::Source but specialized to increase performance when the source is entirely ASCII.
• Prism now provides errors when parsing Ruby 3.4 syntax for index expressions with keywords or blocks.
• Prism now provides an error when **nil is used after other keyword parameters.
• Prism now provides errors when safe navigation is used in call target expressions, e.g., foo&.bar, = 1.
• Prism::Node#tunnel is now provided, which returns an array of nodes starting at the current node that contain a given line and column.

Changed

• All translation layers now assume an eval context, which means they will not return errors for invalid jumps like yield.
• Prism::Node#inspect now uses a queue instead of recursion to avoid stack overflows.
• Prism now more closely mirrors CRuby interpolation semantics, which means you could potentially have a static literal string that directly interpolates another static literal string.
• The shipped RBI sorbet types no longer use generics.
• Prism::ConstantPathNode#child and Prism::ConstantTargetNode#child are now deprecated, replaced by two new fields on these nodes: name and name_loc.
