 ================================================================================
 
-- Accepted values for some client options have changed, this is the new list of
-  accepted values:
+- Ensure compatibility with PHP 8.1.
 
-  - `aggregate`: callable returning an aggregate connection.
-  - `cluster`: string value (`predis`, `redis`), callable returning an aggregate
-    connection.
-  - `replication`: string value (`predis`, `sentinel`), callable returning an
-     aggregate connection.
-  - `commands`: command factory, named array mapping command IDs to PHP classes,
-    callable returning a command factory or a named array.
-  - `connections`: connection factory, callable returning a connection factory,
-    named array mapping connection schemes to PHP classes.
-  - `prefix`: string value, command processor, callable.
-  - `exceptions`: boolean.
 
-  Note that both the `cluster` and `replication` options now return a closure
-  acting as initializer instead of an aggregate connection instance.
+v1.1.7 (2021-04-04)
+================================================================================
 
-- Client option classes now live in the `Predis\Configuration\Option` namespace.
+- __FIX__: with the phpiredis-based connection backends, failed pipelines led to
+spurious responses returned after reconnecting to Redis because the underlying
+reader was not properly reset by discarding buffered replies after disconnecting
+(ISSUE #363).
+- __FIX__: removed `cweagans/composer-patches` dev dependency and apply patches
+using `post-update-cmd` script.
 
-- Classes for Redis commands have been moved into the new `Predis\Command\Redis`
-  namespace and each class name mirrors the respective Redis command ID.
 
-- The concept of server profiles is gone, the library now uses a single command
-  factory to create instances of commands classes. The `profile` option has been
-  replaced by the `commands` option accepting `Predis\Command\FactoryInterface`
-  to customize the underlying command factory. The default command factory class
-  used by Predis is `Predis\Command\RedisFactory` and it still allows developers
-  to define or override commands with their own implementations. In addition to
-  that, `Predis\Command\RedisFactory` relies on a convention-over-configuration
-  approach by looking for a suitable class with the same name as the command ID
-  in the `Predis\Command\Redis` when the internal class map does not contain a
-  class associated.
+v1.1.6 (2020-09-11)
+================================================================================
 
-- The method `Predis\Client::getClientFor($connectionID)` has been replaced by
-  `Predis\Client::on($connectionID, $callable = null)`. This new method returns
-  a new client instance for the specified node just like before when the second
-  argument is omitted, otherwise the callback is invoked and the new client is
-  passed to it. The value returned by the callback is used as the return value
-  of the "on()" method.
+- __FIX__: reverted support for sentinels authentication implemented in v1.1.5
+as it was bugged (see ISSUE #658), sorry for the trouble. This is now postponed
+as it requires a more thorough investigation.
 
-- Changed the signature for the constructor of `Predis\Command\RawCommand`.
 
-- The `Predis\Connection\Aggregate` namespace has been split into two separate
-  namespaces for cluster backends (`Predis\Connection\Cluster`) and replication
-  backends (`Predis\Connection\Replication`).
+v1.1.5 (2020-09-10)
+================================================================================
 
-- The methods `switchToMaster()` and `switchToSlave()` have been promoted to be
-  part of `Predis\Connection\Replication\ReplicationInterface` while the method
-  `switchTo($connection)` has been removed from it.
+- __FIX__:~~authentication for sentinels is now supported, previously it was not
+possible to specify a `password` for sentinels as its value was stripped during
+initialization because sentinels did not support authentication until Redis 5.
+**Please note** that with the current implementation each sentinel must have
+its own `password` parameter set in the parameters list despite this password is
+the same for all sentinels (read how `requirepass` works on the Redis docs). In
+this case you should avoid using the global `parameters` client option used to
+set default parameters for every connection created by Predis as this would end
+up using the same password even when connecting to actual Redis nodes.~~
 
-- The method `Predis\Connection\Cluster\PredisCluster::executeCommandOnNodes()`
-  has been removed as it is possible to achieve the same by iterating over the
-  connection or, even better, over the client instance in order to execute the
-  same command against all of the registered connections.
+- __FIX__: the username is now correctly retrieved from the userinfo fragment of
+the URI when using the "redis" scheme and a "username:password" pair is present.
+Values retrieved from the userinfo fragment always override the ones specified
+in `username` and `password` if those fields are present in the query string.
+
+- __FIX__: `Predis\Connection\WebdisConnection` was unable to connect to Webdis
+when using an IPv4 address in the URL and this is probably due to some change in
+cURL internals since the last time we tested it.
+
+- __FIX__: an exception is thrown whe passing `FALSE` or any value evaluating to
+`FALSE` to the `replication` client option. This was supposed to be unsupported,
+in fact it actually breaks client initialization and raises a PHP warning. Now
+the user is alerted with an `InvalidArgumentException` and a proper message.
+(PR #381).
+
+
+v1.1.4 (2020-08-31)
+================================================================================
+
+- Improved @method annotations for methods responding to Redis commands defined
+  by `Predis\ClientInterface` and `Predis\ClientContextInterface`. (PR #456 and
+  PR #497, other fixes applied after further analysys).
+
+- __FIX__: the client can now handle ACL authentication when connecting to Redis
+  6.x simply by passing both `username` and `password` to connection parameters.
+  See [the Redis docs](https://redis.io/topics/acl) for details on this topic.
+
+- __FIX__: NULL or zero-length string values passed to `password` and `database`
+  in the connection parameters list do not trigger spurious `AUTH` and `SELECT`
+  commands anymore when connecting to Redis (ISSUE #436).
+
+- __FIX__: initializing an iteration over a client instance when it is connected
+  to a standalone Redis server will not throw an exception anymore, instead it
+  will return an iterator that will run for just one loop returning a new client
+  instance using the underlying single-node connection (ISSUE #552, PR #556).
+
+- __FIX__: `Predis\Cluster\Distributor\HashRingaddNodeToRing()` was calculating
+  the hash required for distribution by using `crc32()` directly instead of the
+  method `Predis\Cluster\Hash\HashGeneratorInterface::hash()` implemented by the
+  class itself. This bug fix does not have any impact on existing clusters that
+  use client-side sharding based on this distributor simply because it does not
+  take any external hash generators so distribution is not going to be affected.
+
+- __FIX__: `SORT` now always trigger a switch to the master node in replication
+  configurations instead of just when the `STORE` modifier is specified, this is
+  because `SORT` is always considered to be a write operation and actually fails
+  with a `-READONLY` error response when executed against a replica node. (ISSUE
+  #554).
+
+
+v1.1.3 (2020-08-18)
+================================================================================
+
+- Ensure compatibility with PHP 8.
+
+- Moved repository from `github.com/nrk/predis` to `github.com/predis/predis`.
+
+- __FIX__: Moved `cweagans/composer-patches` dependency to `require-dev`.
+
+- __FIX__: Include PHPUnit `.patch` files in exports.
+
+
+v1.1.2 (2020-08-11)
+================================================================================
+
+- __FIX__: pure CRC16 implementation failed to calculate the correct hash when
+  the input value passed to the `hash()` method is an integer (PR #450).
+
+- __FIX__: make PHP iterator abstractions for `ZSCAN` and `HSCAN` working with
+  PHP 7.2 due to a breaking change, namely the removal of `each()` (PR #448).
+
+
+v1.1.1 (2016-06-16)
+================================================================================
+
+- __FIX__: `password` and `database` from the global `parameters` client option
+  were still being applied to sentinels connections making them fail (sentinels
+  do not understand the `AUTH` and `SELECT` commands) (PR #346).
+
+- __FIX__: when a sentinel instance reports no sentinel for a service, invoking
+  `connect()` on the redis-sentinel connection backend should fall back to the
+  master connection instead of failing (ISSUE #342).
+
+- __FIX__: the two connection backends based on ext-phpiredis has some kind of
+  issues with the GC and the internal use of closures as reader callbacks that
+  prevented connections going out of scope from being properly collected and the
+  underlying stream or socket resources from being closed and freed. This should
+  not have had any actual effect in real-world scenarios due to the lifecycle of
+  PHP scripts, but we fixed it anyway (ISSUE #345).
