 The format is based on [Keep a Changelog](https://keepachangelog.com), and this project adheres to [Semantic Versioning](https://semver.org).
 
+## [2.6.0] - 2021-02-13
+### Added
+* [#856](https://github.com/shlinkio/shlink/issues/856) Added PHP 8.0 support.
+* [#941](https://github.com/shlinkio/shlink/issues/941) Added support to provide a title for every short URL.
+
+    The title can also be automatically resolved from the long URL, when no title was explicitly provided, but this option needs to be opted in.
+
+* [#913](https://github.com/shlinkio/shlink/issues/913) Added support to import short URLs from a standard CSV file.
+
+    The file requires the `Long URL` and `Short code` columns, and it also accepts the optional `title`, `domain` and `tags` columns.
+
+* [#1000](https://github.com/shlinkio/shlink/issues/1000) Added support to provide a `margin` query param when generating some URL's QR code.
+* [#675](https://github.com/shlinkio/shlink/issues/675) Added ability to track visits to the base URL, invalid short URLs or any other "not found" URL, as known as orphan visits.
+
+    This behavior is enabled by default, but you can opt out via env vars or config options.
+
+    This new orphan visits can be consumed in these ways:
+
+      * The `https://shlink.io/new-orphan-visit` mercure topic, which gets notified when an orphan visit occurs.
+      * The `GET /visits/orphan` REST endpoint, which behaves like the short URL visits and tags visits endpoints, but returns only orphan visits.
+
+### Changed
+* [#977](https://github.com/shlinkio/shlink/issues/977) Migrated from `laminas/laminas-paginator` to `pagerfanta/core` to handle pagination.
+* [#986](https://github.com/shlinkio/shlink/issues/986) Updated official docker image to use PHP 8.
+* [#1010](https://github.com/shlinkio/shlink/issues/1010) Increased timeout for database commands to 10 minutes.
+* [#874](https://github.com/shlinkio/shlink/issues/874) Changed how dist files are generated. Now there will be two for every supported PHP version, with and without support for swoole.
+
+    The dist files will have been built under the same PHP version they are meant to be run under, ensuring resolved dependencies are the proper ones.
+
+### Deprecated
+* [#959](https://github.com/shlinkio/shlink/issues/959) Deprecated all command flags using camelCase format (like `--expirationDate`), adding kebab-case replacements for all of them (like `--expiration-date`).
+
+    All the existing camelCase flags will continue working for now, but will be removed in Shlink 3.0.0
+
+* [#862](https://github.com/shlinkio/shlink/issues/862) Deprecated the endpoint to edit tags for a short URL (`PUT /short-urls/{shortCode}/tags`).
+
+    The short URL edition endpoint (`PATCH /short-urls/{shortCode}`) now supports setting the tags too. Use it instead.
+
+### Removed
+* *Nothing*
+
+### Fixed
+* [#988](https://github.com/shlinkio/shlink/issues/988) Fixed serving zero-byte static files in apache and apache-compatible web servers.
+* [#990](https://github.com/shlinkio/shlink/issues/990) Fixed short URLs not properly composed in REST API endpoints when both custom domain and custom base path are used.
+* [#1002](https://github.com/shlinkio/shlink/issues/1002) Fixed weird behavior in which GeoLite2 metadata's `buildEpoch` is parsed as string instead of int.
+* [#851](https://github.com/shlinkio/shlink/issues/851) Fixed error when trying to schedule swoole tasks in ARM architectures (like raspberry).
+
+
 ## [2.5.2] - 2021-01-24
 ### Added
 * [#965](https://github.com/shlinkio/shlink/issues/965) Added docs section for Architectural Decision Records, including the one for API key roles.

-In order to provide pull requests to this project, you should always start by creating a new branch, where you will make all desired changes.
+**Important!**: Before starting to work on a pull request, make sure you always [open an issue](https://github.com/shlinkio/shlink/issues/new/choose) first.
+
+This is important because any contribution needs to be discussed first. Maybe there's someone else already working on something similar, or there are other considerations to have in mind.

+Once everything is clear, to provide a pull request to this project, you should always start by creating a new branch, where you will make all desired changes.
 
 The base branch should always be `develop`, and the target branch for the pull request should also be `develop`.
 
-Before your branch can be merged, all the checks described in [Running code checks](#running-code-checks) have to be passing. You can verify that manually by running `./indocker composer ci`, or wait for the build to be run automatically after the pull request is created.

+# Track visits to 'base_url', 'invalid_short_url' and 'regular_404'
+
+* Status: Accepted
+* Date: 2021-02-07
+
+## Context and problem statement
+
+Shlink has the mechanism to return either custom errors or custom redirects when visiting the instance's base URL, an invalid short URL, or any other kind of URL that would result in a "Not found" error.
+
+However, it does not track visits to any of those, just to valid short URLs.
+
+The intention is to change that, and allow users to track the cases mentioned above.
+
+## Considered option
+
+* Create a new table to track visits o this kind.
+* Reuse the existing `visits` table, by making `short_url_id` nullable and adding a couple of other fields.
+
+## Decision outcome
+
+The decision is to use the existing table, as making the short URL nullable can be handled seamlessly by using named constructors, and it has a lot of benefits on regards of reusing existing components.
+
+Also, the domain name this kind of visits will receive is "Orphan Visits", as they are detached from any existing short URL.
+
+## Pros and Cons of the Options
+
+### New table
+
+* Good because we don't touch existing models and tables, reducing the risk to introduce a backwards compatibility break.
+* Bad because we will have to repeat data modeling and logic, or refactor some components to support both contexts. This in turn increases the options to introduce a BC break.
+
+### Reuse existing table
+
+* Good because all the mechanisms in place to handle visits will work out of the box, including locating visits and such.
+* Bad because we will have more optional properties, which means more double checks in many places.
