0.7.0.1

• Officially drop support for GHC < 7.6 due to usage of Generics.

0.7

• RetryPolicy has become RetryPolicyM, allowing for policy logic to consult the monad context.
• RetryPolicyM now takes a RetryStatus value. Use the function rsIterNum to preserve existing behavior of RetryPolicy only receiving the number.
• The monadic action now gets the RetryStatus on each try. Use const if you don’t need it.
• recoverAll explicitly does not handle the standard async exceptions. Users are encouraged to do the same when using recovering, as catching async exceptions can be hazardous.
• We no longer re-export (<>) from Monoid.
• Utility functions simulatePolicy and simulatePolicyPP have been added which help predict how a policy will behave on each iteration.

0.6

• Actions are now retried in the original masking state, while handlers continue to run in MaskedInterruptible (@maoe)
• Added several tests confirming exception hierarchy semantics under recovering (@ozataman)

0.5

• Mitsutoshi’s backoff work inspired a complete redo of the RetryPolicy interface, replacing it with a monoidal RetryPolicy. The result is a much thinner API that actually provides much more power to the end user.
• Now using microseconds in all premade policies. PLEASE TAKE CARE WHEN UPGRADING. It was a bad idea to use miliseconds and deviate from norms in the first place.

0.4

• Transitioned to using Edward Kmett’s exceptions package instead of monad-control. Use 0.3 series if you still need monad-control support.

0.3

Thanks to John Wiegley and Michael Snoyman for their contributions:

• Now using monad-control instead of MonadCatchIO, which is widely agreed to be broken.
• Now using transformers instead of mtl, which was a broader than needed dependency.
