 ### Changed
 
+- Fixed client generation for trailing-slash paths that return arrays of inline objects. [#7876](https://github.com/microsoft/kiota/issues/7876)
 - C#, Java, Go, PHP, Dart, TypeScript, Python and Ruby client: default value initialization in model classes for DateTime/Date/Time/UUID properties did not compile [#7404](https://github.com/microsoft/kiota/issues/7404)
 - All languages: default value initialization in model classes for numeric/boolean properties was missing [#7404](https://github.com/microsoft/kiota/issues/7404)
 - Fixed a bug where required query parameters from one HTTP operation were leaking into the path-item-level URL template, making them appear required for sibling operations on the same path. [#7292](https://github.com/microsoft/kiota/issues/7292)
