v0.7.0

What's Changed

• Complete revamp by @gdalle in #160
• Remove mention of (now unsupported) kwargs by @gdalle in #162
• Delete build directory by @gdalle in #163

Main breaking changes

• The forward function (now called solver) must return a byproduct z in all cases, which will usually be nothing. It used to be optional. For most users, adaptation will only require replacing forward(x) = y by forward(x) = (y, nothing).
• Support for keyword arguments has been removed.
• Forward rules for Enzyme have been dropped (temporarily).

Please refer to the API reference and FAQ for more details.

Main new features

• The ability to run preparation on the differentiation of conditions. This is useful e.g. to leverage a sparse backend and build Jacobian matrices instead of calling lazy pushforwards and pullbacks

v0.6.0

TLDR

The API has been completely redesigned to use DifferentiationInterface instead of AbstractDifferentiation. Basic use cases should not be significantly altered, but if you were using custom condition backends or solvers, please refer to the documentation.

v0.5.0

In a nutshell

Implicit functions have become more flexible:

• byproducts are optional, and handled automatically via dispatch
• additional positional arguments are supported but not differentiated
• the conditions can be differentiated using a different backend

The linear solver has been generalized:

• it can be chosen among "implicit" and "direct"
• the direct linear solver caches the LU factorization for each pullback or pushforward
• it returns NaNs when the solve fails instead of erroring

General reliability of the package has improved thanks to extensive testing:

• with standard arrays, static arrays and sparse arrays (experimental)
• leveraging ChainRulesTestUtils.jl

See the brand new FAQ page in the docs for more details.
