-### Changed
-- `Schema.Directive` is extended to contain a boolean argument, representing
-  repeatable directives. The parser can parse repeatable directive definitions.
-
-### Fixed
-- `gql` quasi quoter recognizeds all GraphQL line endings (CR, LF and CRLF).
-
-### Added
-- @specifiedBy directive.

-## [1.3.0.0] - 2024-05-01
-### Changed
-- Remove deprecated `runCollectErrs`, `Resolution`, `CollectErrsT` from the
-  `Error` module.

-## [1.2.0.3] - 2024-01-09
-### Fixed
-- Fix corrupted source distribution.
-
-## [1.2.0.2] - 2024-01-09
 ### Fixed
 - `gql` removes not only leading `\n` but also `\r`.
-- Fix non nullable type string representation in executor error messages.
-- Fix input objects not being coerced to lists.
-- Fix used variables are not found in the properties of input objects.
