-## Added
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.3.0] - TBD
+
+## [1.2.0] - 2022-12-01
+
+### Added
 
 - Adds `UriIntegrationTest::testGetPathNormalizesMultipleLeadingSlashesToSingleSlashToPreventXSS()`, `UriIntegrationTest::testStringRepresentationWithMultipleSlashes(array $test)`, and `RequestIntegrationTest::testGetRequestTargetInOriginFormNormalizesUriWithMultipleLeadingSlashesInPath()`.
   These validate that a path containing multiple leading slashes is (a) represented with a single slash when calling `UriInterface::getPath()`, and (b) represented without changes when calling `UriInterface::__toString()`, including when calling `RequestInterface::getRequestTarget()` (which returns the path without the URI authority by default, to comply with origin-form).
   This is done to validate mitigations for [CVE-2015-3257](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-3257).
 
-## Changed
+### Changed
 
 - Modifies `UriIntegrationTest::testPathWithMultipleSlashes()` to only validate multiple slashes in the middle of a path.
   Multiple leading slashes are covered with the newly introduced tests.
