I'm pleased to announce Botan 2.7.0 has been released. Focus this release is on
performance and side channel hardening.

 - Address side channels in RSA key generation and ECDSA signing

 - Side channel hardening in many core algorithms (modular exponentiation, ECC
   scalar multiply, Karatsuba multiplication, Barrett reduction, etc) to reduce
   the risk of future exploitable side channels.

 - Many optimizations for ECC operations, RSA (including key gen), DSA, DH, and
   XMSS. Typical speedups vs 2.6.0 is 10 to 40% depending on operation and key

 - Add Scrypt password hashing. Also supported is using Scrypt to derive keys
   for private key encryption (format compatible with upcoming OpenSSL 1.1.1)

 - Add base32 encoding/decoding

 - Plus many bug fixes and smaller enhancements documented in the release notes:
