0.5 [2025.01.25]

• Add a generateHyperLogLog function that randomly generates a HyperLogLog value using system entropy. This function is suitable for scenarios where cryptographic security is a primary consideration.

• Add an additional s type parameter to HyperLogLog that encodes the SipKey used to configure the hash function when inserting new values. (Previously, inserting a new value would always use a fixed SipKey.)

  In order to continue using the old behavior of the insert function, one can instantiate s to the newly added DefaultSipKey type. Note that this is not cryptographically secure, however. (In contrast, the generateHyperLogLog function instantiates s with a randomly generated SipKey.)

• Export the SipKey data type and define a reifySipKey function to promote a SipKey value to the type level.

• Define a type DefaultHyperLogLog = HyperLogLog DefaultSipKey type synonym.

• Drop support for GHC 8.0.

0.4.6 [2022.04.18]

• Remove the siphash dependency. Because siphash no longer builds on GHC 9.2+, we instead bundle the code alongside hyperloglog. This allows hyperloglog to build with 9.2.

0.4.5 [2021.11.16]

• Drop support for pre-8.0 versions of GHC.
• Allow building with hashable-1.4.*.

0.4.4 [2021.02.17]

• Allow building with lens-5.*.
• The build-type has been changed from Custom to Simple. To achieve this, the doctests test suite has been removed in favor of using cabal-docspec to run the doctests.

0.4.3 [2019.09.13]

• Remove unused safecopy dependency.

0.4.2

• Add a library dependency on the doctests test suite

0.4.1

• Revamp Setup.hs to use cabal-doctest. This makes it build with Cabal-2.0, and makes the doctests work with cabal new-build and sandboxes.
• Drop (unused) hashable-extras dependency
• Add NFData instance for HyperLogLog
• Require GHC 7.8 or later

0.4.0.4

• Support cereal 0.5 and safecopy 0.9.

0.4.0.3

• Fixed doctest issues caused by vector 0.11
• Unfortunately the herbie changes turned out to be flawed (due to issue mikeizbicki/HerbiePlugin#8). Rolling them back for now.

0.4.0.2

• Fixed a haddock issue caused by the comments in the herbie code.

0.4.0.1

• Added vector 0.11 support.
• Incorporated some changes suggested by the HerbiePlugin.

0.3.4

• Support generic-deriving 1.8. We no longer incur a generic-deriving requirement at all except on GHC < 7.6.

0.3.3.1

• Support reflection 2

0.3.3

• Added bytes and binary instances.
• Compiles warning-free on GHC 7.10.

0.3.2

• Simplified reifyConfig internals.

0.3.1

• Added insertHash. This enables users of the 0.2 era version of hyperloglog to manually pick the hash used and load their old data.
• Builds warning-free on GHC 7.10

0.3.0.1

• Constraint bumps for lens and generic-deriving

0.3

• Switched to SipHash, so the package actually works.

0.2.3.2

• More #ifdef bugfixes

0.2.3.1

• #ifdef bugfix

0.2.3

• GHC 7.8 compatibility
• Bumped cereal dependency.

0.2.1

• Exported insert from Data.HyperLogLog.

0.2

• Made compatible with lens 4

0.1

• Ported Data.Analytics.Approximate.HyperLogLog from analytics into a separate package.
