Flax is a high-performance neural network library for JAX that is designed for
flexibility: Try new forms of training by forking an example and by modifying
the training loop, not by adding features to a framework.

JAX is Autograd and XLA, brought together for high-performance machine learning
research.
With its updated version of Autograd, JAX can automatically differentiate native
Python and NumPy functions. It can differentiate through loops, branches,
recursion, and closures, and it can take derivatives of derivatives of
derivatives. It supports reverse-mode differentiation (a.k.a. backpropagation)
via grad as well as forward-mode differentiation, and the two can be composed
arbitrarily to any order.
What's new is that JAX uses XLA to compile and run your NumPy programs on GPUs
and TPUs. Compilation happens under the hood by default, with library calls
getting just-in-time compiled and executed. But JAX also lets you just-in-time
compile your own Python functions into XLA-optimized kernels using a
one-function API, jit. Compilation and automatic differentiation can be composed
arbitrarily, so you can express sophisticated algorithms and get maximal
performance without leaving Python. You can even program multiple GPUs or TPU
cores at once using pmap, and differentiate through the whole thing.
Dig a little deeper, and you'll see that JAX is really an extensible system for
composable function transformations. Both grad and jit are instances of such
transformations. Others are vmap for automatic vectorization and pmap for
single-program multiple-data (SPMD) parallel programming of multiple
accelerators, with more to come.

Optimized einsum can significantly reduce the overall execution time of
einsum-like expressions (e.g., np.einsum, dask.array.einsum, pytorch.einsum,
tensorflow.einsum, ) by optimizing the expression's contraction order and
dispatching many operations to canonical BLAS, cuBLAS, or other specialized
routines. Optimized einsum is agnostic to the backend and can handle NumPy,
Dask, PyTorch, Tensorflow, CuPy, Sparse, Theano, JAX, and Autograd arrays as
well as potentially any library which conforms to a standard API.

the pinentry supports this. [#4971]

--enable-issuer-based-crl-check can be used to revert to the
former behaviour.

exiv2 added -fcf-protection, which is not supported on either ARM or PPC.
1ea63ccb34 fixes that but only for ARM.
Merge this commit and add modify it to also fix PPC. This is likely the wrong approach, since -fcf-protection seems to be available only on amd64, but this is the approach that upstream chose.
MFH: 2020Q3 (fix build blanket)
As opposed to MySQL 8.0.x branch that switched to dynamic linking for OpenSSL libraries, MySQL 5.7.30 still statically links client applications with OpenSSL.
Meantime, OpenSSL supports dynamic loading of external engines like security/gost-engine. If such engine is configured to load in the openssl.cnf, mysql CLI application crashes at start with SIGSEGV early trying to initialize OpenSSL.
This loads dynamic engine library libgost.so that calls OpenSSL function using second (uninitialized) instance of OpenSSL leading to crash.
The problem is fixed with small backport from MySQL 8.0.x for cmake/ssl.cmake distribution file we already patching anyway.
