Released pbc-0.4.15
I stopped a crash when element_from_hash is called for GT on type D curves. Thanks to Paul Miller for reporting the bug.
Due to a horrible hashing routine, which I hope to fix one day, hashing to GT for D curves map everything to 1. The crash occurred because standardizing the coset representative uses an optimization involving Lucas sequences, which divides by zero when given 1.

SSARES: Secure Searchable Automated Remote Email Storage
Adam Aviv has released an application for SSARES: Secure Searchable Automated Remote Email Storage, which uses the PBC library.
His code originally used PBC version 0.2.16, an ancient version of PBC. He recently converted to the latest version: 0.4.12. If anyone else needs to do this same, the main obstacles Adam reported are:
-
element_pow is now element_pow_mpz
-
element_from_hash has swapped the order of the last two parameters
-
pairing_apply is the current name for executing a pairing (without preprocessing)
