1.3.2 – 2018-07-06

Other Changes

• Support free-5.1.

---

1.3.1

• Add MonadUnliftIO instance for LoggingT.

---

1.3.0

Major Changes

• Switch from wl-pprint-text to prettyprinter.

Other changes

• Change the type of the ribbonFrac parameter of withFDHandler from Float to Double to reflect the underlying prettyprinter API.

---

1.2.6

Other Changes

• Increased upper bound of base and support GHC 8.4.

---

1.2.5

Other Changes

• Increased upper bound of exceptions.

---

1.2.4

Other Changes

• Increased upper bound of exceptions.

---

1.2.3

Other Changes

• Increased upper of async.

---

1.2.2

Other Changes

• Increased upper bound of free and time.

---

1.2.1

Other Changes

• Increased upper bound of base to allow < 4.11.

---

1.2.0

Major Changes

• withFDHandler now explicitly flushes the file handle whenever log entries are rendered out. Thanks to @filterfish for identifying this omission that could lead to log messages being dropped.

  Upgrade steps: no changes other than updating logging-effect.

---

1.1.3

Other Changes

• Increased upper bound of time to allow < 1.9.

---

1.1.2

Other changes

• Increased upper bound of time

---

1.1.1

• withBatchedHandler no longer prints empty log messages. Previously, if you ran a program that didn’t log but used withBatchedHandler (or anything that used that), an empty log message would be output. Thanks to @codedmart for fixing this.

---

1.1.0

Breaking changes:

• MonadLog no longer has logMessage as a function. It now has logMessageFree which takes a free monoid of log messages. If you were just using logging-effect then this won’t affect you, as logMessage still exists with the same signature outside the type class.

• MonadLog now comes with a law that states that logging is a monoid homomorphism. This essentially means that you have to treat all log messages uniformly.

• Pass-through instances for all “stock” monad transformers have been added (all of transformers, CatchT from exceptions and FreeT/FT from free).

• WithSeverity now has instances of Traversable and Foldable

• WithTimestamp now has instances of Eq, Ord, Read and Show.

Additions:

• A set of convenience functions have been added for quickly logging with severity. The combinators are: logDebug, logInfo, logNotice, logWarning, logError, logCritical, logAlert and logEmergency.

• mapLogMessage got a companion function mapLogMessageM that works with monadic tranformations.

Other

• Many documentation bug fixes.

• INLINEABLE pragmas added.
