 ## [Unreleased]
 
+## [4.2.1] - 2019-05-06
+### Changed
+- Improved Keep-Alive settings for HTTP client used to perform requests to Mojang's APIs.
+- Mojang's textures queue now has static delay of 1 second after each iteration to prevent strange `429` errors.
+- Mojang's textures queue now caches even errored responses for signed textures to avoid `429` errors.
+- Mojang's textures queue now caches textures data for 70 seconds to avoid strange `429` errors.
+- Mojang's textures queue now doesn't log timeout errors.
+
+### Fixed
+- Panic when Redis connection is broken.
+- Duplication of Redis connections pool for Mojang's textures queue.
+- Removed validation rules for `hash` field.
