3.2

• Renamed Chain to Wengert to reflect its use of Wengert lists for reverse mode.
• Renamed lift to auto to avoid conflict with the more prevalent transformers library.
• Fixed a bug in Numeric.AD.Forward.gradWith', which caused it to return the wrong value for the primal.

3.1.4

• Added a better "convergence" test for findZero
• Compute tan and tanh derivatives directly.

3.1.3

• Added conjugateGradientDescent and conjugateGradientAscent to Numeric.AD.Newton.

3.1.2

• Dependency bump

3.1

• Added Chain mode, which is Reverse using a linear tape that doesn't need to be sorted.
• Added a suite of doctests.
• Bug fix in Forward mode. It was previously yielding incorrect results for anything that used bind or bind' internally.

3.0

• Moved the contents of Numeric.AD.Mode.Mixed into Numeric.AD
• Split off Numeric.AD.Variadic for the variadic combinators
• Removed the UU, FU, UF, and FF type aliases.
• Stopped exporting the types for Mode and AD from almost every module. Import Numeric.AD.Types if necessary.
• Renamed Tensors to Jet
• Dependency bump to be compatible with ghc 7.4.1 and mtl 2.1
• More aggressive zero tracking.
• diff (**n) 0 for constant n and diff (0**) both now yield the correct answer for all modes.
