+
+### Bug Fixes
+
+* **core:** fix the Axios constructor implementation to treat the config argument as optional; ([#6881](https://github.com/axios/axios/issues/6881)) ([6c5d4cd](https://github.com/axios/axios/commit/6c5d4cd69286868059c5e52d45085cb9a894a983))
+* **fetch:** fixed ERR_NETWORK mapping for Safari browsers; ([#6767](https://github.com/axios/axios/issues/6767)) ([dfe8411](https://github.com/axios/axios/commit/dfe8411c9a082c3d068bdd1f8d6e73054f387f45))
+* **headers:** allow iterable objects to be a data source for the set method; ([#6873](https://github.com/axios/axios/issues/6873)) ([1b1f9cc](https://github.com/axios/axios/commit/1b1f9ccdc15f1ea745160ec9a5223de9db4673bc))
+* **headers:** fix `getSetCookie` by using 'get' method for caseless access; ([#6874](https://github.com/axios/axios/issues/6874)) ([d4f7df4](https://github.com/axios/axios/commit/d4f7df4b304af8b373488fdf8e830793ff843eb9))
+* **headers:** fixed support for setting multiple header values from an iterated source; ([#6885](https://github.com/axios/axios/issues/6885)) ([f7a3b5e](https://github.com/axios/axios/commit/f7a3b5e0f7e5e127b97defa92a132fbf1b55cf15))
+* **http:** send minimal end multipart boundary ([#6661](https://github.com/axios/axios/issues/6661)) ([987d2e2](https://github.com/axios/axios/commit/987d2e2dd3b362757550f36eab875e60640b6ddc))
+* **types:** fix autocomplete for adapter config ([#6855](https://github.com/axios/axios/issues/6855)) ([e61a893](https://github.com/axios/axios/commit/e61a8934d8f94dd429a2f309b48c67307c700df0))
+
+
+### Features
+
+* **AxiosHeaders:** add getSetCookie method to retrieve set-cookie headers values ([#5707](https://github.com/axios/axios/issues/5707)) ([80ea756](https://github.com/axios/axios/commit/80ea756e72bcf53110fa792f5d7ab76e8b11c996))
