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.
