This is the main package for Yesod, providing all core functionality on which
other packages can be built. It provides dispatch, handler functions, widgets,
etc.
Derive a Show instance for ResourceTree and FlatResource#1492
Some third party packages, like yesod-routes-flow derive their own Show instance, and this will break those packages.
1.6.1
Add a Semigroup LiteApp instance, and explicitly define (<>) in the
already existing Semigroup instances for WidgetFor, Head, Body,
GWData, and UniqueList.

Upgrade to conduit 1.3.0
Switch to MonadUnliftIO
Drop mwc-random and blaze-builder dependencies
Strictify some internal data structures
Add CI wrapper to first field in Header data constructor
#1418
Internal only change, users of stable API are unaffected: WidgetT
holds its data in an IORef so that it is isomorphic to ReaderT,
avoiding state-loss issues..
Overhaul of HandlerT/WidgetT to no longer be transformers.

Add guessApproot and guessApprootOr
1.4.15.1
bugfix neverExpires leaked threads
1.4.15
mkYesod avoids using reify when it isn’t necessary. This avoids needing to define the site type below the call to mkYesod.
1.4.14
Add CSRF protection functions and middleware based on HTTP cookies and headers #1017
Add mkYesodWith, which allows creating sites with polymorphic type parameters #1055
Do not define the site type below a call to mkYesod (or any variant), as it will be required at splicing time for reification.
This was allowed before because reification was not in use. Reification was introduced to allow parametrized types to be used
by mkYesod (and variants), with potentially polymorphic variables.
