This release increases the default signing table size from 22 KiB to 86 Kib, and adds example code for ElligatorSwift-based key exchange.

This release includes algorithmic improvements which increase the speed of key generation and signing. At the same time, the binary size has been reduced significantly, which we expect to benefit embedded users in particular. Moreover, a new function to sort public keys has been added.

This release slightly increases the speed of the ECDH operation and significantly enhances the performance of many library functions when using the default configuration on x86_64.

This release fixes a "constant-timeness" issue in the ECDH implementation with GCC >=13 that could leave applications using libsecp256k1 vulnerable to a timing side-channel attack. We strongly recommend any users of the library to upgrade if their code may end up being compiled with an affected version of GCC.
