 ## UNRELEASED
 
+## 1.5.0 (2019-08-24)
+
+### Added 
+
+* added `Assert::uniqueValues()`
+* added `Assert::unicodeLetters()`
+* added: `Assert::email()`
+* added support for [Psalm](https://github.com/vimeo/psalm), by adding `@psalm-assert` annotations where appropriate.
+
+## Fixed
+
+* `Assert::endsWith()` would not give the correct result when dealing with multibyte suffix. 
+* `Assert::length(), minLength, maxLength, lengthBetween` would not give the correct result when dealing with multibyte characters. 
+
+**NOTE**: These 2 changes may break your assertions if you relied on the fact that multibyte characters didn't behave correctly.
+
+## Changed
+
+* The names of some variables have been updated to better reflect what they are.
+* All function calls are now in their FQN form, slightly increasing performance.
+* Tests are now properly ran against HHVM-3.30 and PHP nightly.
+
+### Deprecation
+
+* deprecated `Assert::isTraversable()` in favor of `Assert::isIterable()`
+  * This was already done in 1.3.0, but it was only done through a silenced `trigger_error`. It is now annotated as well.
