 # ChangeLog for yesod-auth
 
-## Unreleased
+## 1.6.11.2

+
+* No star is type [#1797](https://github.com/yesodweb/yesod/pull/1797)
+
+## 1.6.11
+
+* Add support for aeson 2
+
+## 1.6.10.5
+
+* Fix German translations of AuthMessage [#1741](https://github.com/yesodweb/yesod/pull/1741)
+
+## 1.6.10.4
+
+* Add support for GHC 9 [#1737](https://github.com/yesodweb/yesod/pull/1737)
+
+## 1.6.10.3
+
+* Relax bounds for yesod-form 1.7
+
+## 1.6.10.2
+
+* Relax bounds for persistent 2.12
+
+## 1.6.10.1
+
+* Add support for Persistent 2.11 [#1701](https://github.com/yesodweb/yesod/pull/1701)
+
+## 1.6.10
+
+* Updated `AuthMessage` data type in `Yesod.Auth.Message` to accommodate registration flow where password is supplied initially: deprecated `AddressVerified` and split into `EmailVerifiedChangePass` and `EmailVerified`
+* Fixed a bug in `getVerifyR` related to the above, where the incorrect message was displayed when password was set during registration
+* Added `sendForgotPasswordEmail` to `YesodAuthEmail` typeclass, allowing for different emails for account registration vs. forgot password
+* See pull request [#1662](https://github.com/yesodweb/yesod/pull/1662)
+
+## 1.6.9
+
+* Added `registerHelper` and `passwordResetHelper` methods to the `YesodAuthEmail` class, allowing for customizing behavior for user registration and forgot password requests [#1660](https://github.com/yesodweb/yesod/pull/1660)
+* Exposed `defaultRegisterHelper` as default implementation for the above methods
+
+## 1.6.8.1
 
 * Email: Fix typo in `defaultEmailLoginHandler` template [#1605](https://github.com/yesodweb/yesod/pull/1605)
+* Remove unnecessary deriving of Typeable
 
 ## 1.6.8

 # ChangeLog for yesod-core
 
+## 1.6.25.1
+
+* Export the options that were created in 1.6.25.0 [#1825](https://github.com/yesodweb/yesod/pull/1825)
+
+## 1.6.25.0
+
+* Add an options structure that allows the user to set which instances will be derived for a routes structure. [#1819](https://github.com/yesodweb/yesod/pull/1819)
+
+## 1.6.24.5
+
+* Support Aeson 2.2 [#1818](https://github.com/yesodweb/yesod/pull/1818)
+
+## 1.6.24.4
+
+* Fix test-suite compilation error for GHC >= 9.0.1 [#1812](https://github.com/yesodweb/yesod/pull/1812)
+
+## 1.6.24.3
+
+* Fix subsite-to-subsite dispatch [#1805](https://github.com/yesodweb/yesod/pull/1805)
+
+## 1.6.24.2
+
+* No star is type [#1797](https://github.com/yesodweb/yesod/pull/1797)
+
+## 1.6.24.1
+
+* Adapt to removal of `ListT` from transformers-0.6. [#1796](https://github.com/yesodweb/yesod/pull/1796)

+
+## 1.6.23
+
+* Add idempotent versions of `setDescription`, `setDescriptionI`. These functions
+  have odd behaviour when called multiple times, so they are now warned against.
+  This can't be a silent change - if you want to switch to the new functions, make
+  sure your layouts are updated to use `pageDescription` as well as `pageTitle`.
+  [#1765](https://github.com/yesodweb/yesod/pull/1765)
+

+* Handle async exceptions within yesod rather then warp. [#1753](https://github.com/yesodweb/yesod/pull/1753)
+* Support template-haskell 2.18 [#1754](https://github.com/yesodweb/yesod/pull/1754)
+
+## 1.6.21.0
+
+* Export `Yesod.Core.Dispatch.defaultGen` so that users may reuse it for their own `YesodRunnerEnv`s [#1734](https://github.com/yesodweb/yesod/pull/1734)
+
+## 1.6.20.2

+
+* Fixed a bug where `mkYesod` and other TH functions didn't work for datatypes with explicitly stated type variables, including the case with typeclass constraints. [https://github.com/yesodweb/yesod/pull/1697](#1697)
+
+## 1.6.18.3
+
+* Remove mention of an oudated Yesod type (`GHandler`) from the docs for `handlerToIO`. [https://github.com/yesodweb/yesod/pull/1695](#1695)

+-- | The general structure of each individually generated field is as follows.
+-- There is an external wrapper element containing both an inner wrapper and any
+-- error messages that apply to that specific field. The inner wrapper contains
+-- both the field and it's corresponding delete button.
+--
+-- The structure is illustrated by the following:
+-- 
+-- > <div .#{wrapperClass}>
+-- >     <div .#{wrapperClass}-inner>
+-- >         ^{fieldWidget}
+-- >         ^{deleteButton}
+-- >     ^{maybeErrorMessages}
+--
+-- Each wrapper element has the same class which is automatically generated. This class
+-- is returned in the 'MultiView' should you wish to change the styling. The inner wrapper
+-- uses the same class followed by @-inner@. By default the wrapper and inner wrapper has
+-- classes are as follows:
+-- 
+-- > .#{wrapperClass} {
+-- >     margin-bottom: 1rem;
+-- > }
+-- >
+-- > .#{wrapperClass}-inner {
+-- >     display: flex;
+-- >     flex-direction: row;
+-- > }

 -- $optionsOverview
 -- These functions create inputs where one or more options can be selected from a list.
--- 
+--
 -- The basic datastructure used is an 'Option', which combines a user-facing display value, the internal Haskell value being selected, and an external 'Text' stored as the @value@ in the form (used to map back to the internal value). A list of these, together with a function mapping from an external value back to a Haskell value, form an 'OptionList', which several of these functions take as an argument.
--- 
+--
 -- Typically, you won't need to create an 'OptionList' directly and can instead make one with functions like 'optionsPairs' or 'optionsEnum'. Alternatively, you can use functions like 'selectFieldList', which use their @[(msg, a)]@ parameter to create an 'OptionList' themselves.
