Changelog for io-classes-1.8.0.1

Revsion history of io-classes

1.8.0.1

Added support for ghc-9.2.

1.8.0.0 Breaking changes

Provided MonadTraceMVar
Renamed InspectMonad to InspectMonadSTM
Added threadLabel to MonadThread
Added MonadLabelledMVar class.
Added labelMVar to Control.Concurrent.Class.MonadMVar.Strict
Added debugTraceTVar, debugTraceTMVar, debugTraceTVarIO, debugTraceTMVarIO for Show-based tracing.
MonadEvaluate is not a supper-class of MonadThrow anymore.
Moved all MonadMaskingState methods to MonadMask. MonadMaskingState is available but deprecated, it will be removed in one of the future releases.
io-classes:mtl instances support the extended MonadMask instance.

Non-breaking changes

Added monad transformer instances for MonadInspectSTM & MonadTraceSTM type classes.
Support ghc-9.12

1.7.0.0 Breaking changes

Renamed io-classes:io-classes-mtl as io-classes:mtl.

1.6.0.0 Breaking changes

strict-stm, strict-mvar and si-timers are now public sublibraries of io-classes package.
Moved io-classes-mtl to io-classes as a public sublibrary.

1.5.0.0

Breaking changes

MonadST depends on PrimMonad.
Provide a default implementation of withLiftST.
Added annotateIO to MonadThrow (only supported for ghc-9.10 or newer).

Non-breaking change

Add writeTMVar to MonadSTM.
strict-stm, strict-mvar and si-timers were moved to io-classes as public sublibraries. You can import then in *.cabal files with the following syntax io-classes:strict-stm or io-classes:{strict-stm, si-timers}. See the Multiple public libraries subsection of Internal Libraries section in the cabal documentation.

Note: some time in the future we will deprecate Hackage packages strict-stm, strict-mvar and si-timers. If one will want to use the namespace for a non io-classes related packages please contact the maintainer.

1.4.1.0

Non-breaking changes

New dependency on primitive package
New stToIO in MonadST, which is simpler to use than the existing withLiftST, and depends on the primitive package's PrimState (#141).

1.4.0.0

Breaking changes

Removed deprecated module Control.Monad.Class.MonadVar.

Non-breaking changes

Fixed some module haddock typos.

1.3.1.0

Non-breaking changes

Added forkFinally to MonadFork.

1.3.0.0

io-sim-1.3.0.0.

Support ghc-9.8.

1.2.0.0

Non-breaking changes

Add new MonadInspectMVar class with an inspectMVar function for accessing an MVar in an underlying monad (if applicable). This is mainly useful for io-sim, since the underlying monad is ST. IO has no underlying monad, so the provided instance for IO defaults inspectMVar to tryReadMVar.
Add some Haddock documentation to MonadDelay

1.1.0.0

Breaking changes

Control.Monad.Class.MonadMVar is now deprecated in favour of Control.Concurrent.Class.MonadMVar.

Non breaking changes

Fixed building haddocks with ghc-8.10.

1.0.0.1

Non breaking changes

Support ghc-9.6.

1.0.0.0

Breaking changes

MonadMonotonicTime morphed into MonadMonotonicTimeNSec which supports getMonotonicTimeNSec from "base". MonadMonotonicTime can be found in new package si-timers.
A simplified MonadTimer which is using time in microseconds encoded as Int rather than DiffTime. The previous interface can be found in the package si-timers.
The non standard timer API is moved from MonadTimer to a MonadTimerFancy type class which can be imported from Control.Monad.Class.MonadTimer.NonStandard module.

Non breaking changes

Added registerDelayCancellable to Control.Monad.Class.MonadTimer module.

0.6.0.0

0.5.0.0

fixed tryTakeMVarDefault, takeMVarDefault, putMVarDefault and isEmptyMVarDefault.
Implemented the proper readMVar semantics.
Added tryReadMVar to MonadMVar type class.
Moved MVarDefault to io-sim package.

0.4.0.0

support ghc-9.4 (except on Windows input-output-hk/io-sim#51)

0.3.0.0

added missing MArray instance for WrappedSTM
added monoid instances for WrappedSTM
added threadStatus method of MonadFork class
removed linktTo and linkToOnly
added labelTChan
