 # CHANGELOG
 
+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).
+
+## 1.14.0 - 2018-11-16
+
+#### Added
+
+* [#236](https://github.com/shlinkio/shlink/issues/236) Added option to define a redirection to a custom URL when a user hits an invalid short URL.
+
+    It only affects URLs matched as "short URL" where the short code is invalid, not any 404 that happens in the app. For example, a request to the path `/foo/bar` will keep returning a 404.
+
+    This new option will be asked by the installer both for new shlink installations and for any previous shlink version which is updated.
+
+* [#189](https://github.com/shlinkio/shlink/issues/189) and [#240](https://github.com/shlinkio/shlink/issues/240) Added new [GeoLite2](https://dev.maxmind.com/geoip/geoip2/geolite2/)-based geolocation service which is faster and more reliable than previous one.
+
+    It does not have API limit problems, since it uses a local database file.
+
+    Previous service is still used as a fallback in case GeoLite DB does not contain any IP address.
+
+#### Changed
+
+* [#241](https://github.com/shlinkio/shlink/issues/241) Fixed columns in `visit_locations` table, to be snake_case instead of camelCase.
+* [#228](https://github.com/shlinkio/shlink/issues/228) Updated how exceptions are serialized into logs, by using monlog's `PsrLogMessageProcessor`.
+* [#225](https://github.com/shlinkio/shlink/issues/225) Performance and maintainability slightly improved by enforcing via code sniffer that all global namespace classes, functions and constants are explicitly imported.
+* [#196](https://github.com/shlinkio/shlink/issues/196) Reduced anemic model in entities, defining more expressive public APIs instead.
+* [#249](https://github.com/shlinkio/shlink/issues/249) Added [functional-php](https://github.com/lstrojny/functional-php) to ease collections handling.
+* [#253](https://github.com/shlinkio/shlink/issues/253) Increased `user_agent` column length in `visits` table to 512.
+* [#256](https://github.com/shlinkio/shlink/issues/256) Updated to Infection v0.11.
+* [#202](https://github.com/shlinkio/shlink/issues/202) Added missing response examples to OpenAPI docs.
+
+#### Deprecated

+* *Nothing*
+
+#### Removed
+
+* *Nothing*

+#### Fixed
+
+* [#223](https://github.com/shlinkio/shlink/issues/223) Fixed PHPStan errors produced with symfony/console 4.1.5
+
+
+## 1.13.2 - 2018-10-18
+
+#### Added
+
+* [#233](https://github.com/shlinkio/shlink/issues/233) Added PHP 7.3 to build matrix allowing its failure.
+
+#### Changed
+
+* [#235](https://github.com/shlinkio/shlink/issues/235) Improved update instructions (thanks to [tivyhosting](https://github.com/tivyhosting)).
+

+* *Nothing*

+
+* *Nothing*
+
+#### Fixed
+
+* [#237](https://github.com/shlinkio/shlink/issues/233) Solved errors when trying to geo-locate `null` IP addresses.
+
+    Also improved how visitor IP addresses are discovered, thanks to [akrabat/ip-address-middleware](https://github.com/akrabat/ip-address-middleware) package.

+
+
+## 1.13.0 - 2018-10-06
+
+#### Added
+
+* [#197](https://github.com/shlinkio/shlink/issues/197) Added [cakephp/chronos](https://book.cakephp.org/3.0/en/chronos.html) library for date manipulations.
+* [#214](https://github.com/shlinkio/shlink/issues/214) Improved build script, which allows builds to be done without "jumping" outside the project directory, and generates smaller dist files.
+
+    It also allows automating the dist file generation in travis-ci builds.
+
+* [#207](https://github.com/shlinkio/shlink/issues/207) Added two new config options which are asked during installation process. The config options already existed in previous shlink version, but you had to manually set their values.
+
+    These are the new options:
+
+    * Visits threshold to allow short URLs to be deleted.
+    * Check the visits threshold when trying to delete a short URL via REST API.
+
+#### Changed
+
+* [#211](https://github.com/shlinkio/shlink/issues/211) Extracted installer to its own module, which will simplify moving it to a separated package in the future.
+* [#200](https://github.com/shlinkio/shlink/issues/200) and [#201](https://github.com/shlinkio/shlink/issues/201) Renamed REST Action classes and CLI Command classes to use the concept of `ShortUrl` instead of the concept of `ShortCode` when referring to the entity, and left the `short code` concept to the identifier which is used as a unique code for a specific `Short URL`.
+* [#181](https://github.com/shlinkio/shlink/issues/181) When importing the configuration from a previous shlink installation, it no longer asks to import every block. Instead, it is capable of detecting only new config options introduced in the new version, and ask only for those.
+
+    If no new options are found and you have selected to import config, no further questions will be asked and shlink will just import the old config.
+
+#### Deprecated
+
+* [#205](https://github.com/shlinkio/shlink/issues/205) Deprecated `[POST /authenticate]` endpoint, and allowed any API request to be automatically authenticated using the `X-Api-Key` header with a valid API key.
+
+    This effectively deprecates the `Authorization: Bearer <JWT>` authentication form, but it will keep working.
+
+* As of [#200](https://github.com/shlinkio/shlink/issues/200) and [#201](https://github.com/shlinkio/shlink/issues/201) REST urls have changed from `/short-codes/...` to `/short-urls/...`, and the command namespaces have changed from `short-code:...` to `short-url:...`.
+
+    In both cases, backwards compatibility has been retained and the old ones are aliases for the new ones, but the old ones are considered deprecated.
+
+#### Removed
+
+* *Nothing*
+
+#### Fixed
+
+* [#203](https://github.com/shlinkio/shlink/issues/203) Fixed some warnings thrown while unzipping distributable files.
+* [#206](https://github.com/shlinkio/shlink/issues/206) An error is now thrown during installation if any required param is left empty, making the installer display a message and ask again until a value is set.
+
+
