PLEASE NOTE: This is still marked as an unstable development version.

This release of Libgcrypt contains several important API changes,
please see below for details.

Noteworthy changes since version 1.1.12
---------------------------------------

 All types have been renamed to conform to the GNU coding standards,
 most of the time by keeping the whole name in lowercase and inserting
 underscores between words.

 The concept of a Libgcrypt specific `errno' variable has been dropped
 entirely.  Functions that used to set this errno variable, return an
 appropriate error code directly.

 Libgcrypt depends on libgpg-error, a library that provides error codes
 and according functions for all GnuPG components.  Functions that used
 to return error codes asa `int' have been changed to return a code of
 type `gcry_error_t'.

 A new interface for the use of asymmetric cryptography is included.

 Backward compatibility is provided where it was possible without too
 much effort and did not collide with the overall sanitization effort.
 However, this is only for ease of transition.  NO DEPRECATED FUNCTION
 OR DATA TYPE IS CONSIDERED A PART OF THE API OR ABI AND WILL BE
 DROPPED IN THE FUTURE WITHOUT CHANGING THE SONAME OF THE LIBRARY.
 Recommendations how to replace deprecated or removed functionality can
 be found within the description of each change.

 What follows are all changes to the interface and behaviour of
 Libgcrypt in detail.

 * If gcrypt.h is included in sources compiled by GCC 3.1 or later,
   deprecated attributes will warn about use of obsolete functions and
   type definitions.  You can suppress these warnings by passing
   -Wno-deprecated-declarations to the gcc command.

 * gcry_check_version must be called from now on to initialize the
   library, it is not longer optional.

 * The following types have been renamed.  The old types are still
   available as aliases, but they are deprecated now:
   Old name:		New name:
   GCRY_MPI		gcry_mpi_t
   GcryMPI		gcry_mpi_t
   GCRY_SEXP            gcry_sexp_t
   GcrySexp             gcry_sexp_t
   GCRY_CIPHER_HD       gcry_cipher_hd_t
   GcryCipherHd		gcry_cipher_hd_t
   GCRY_MD_HD		gcry_md_hd_t
   GcryMDHd		gcry_md_hd_t

 * All GCRYERR_* error symbols have been removed, since they are now
   contained in libgpg-error (GPG_ERR_*).

 * All functions and types in libgpg-error have been wrapped in
   Libgcrypt. The new types are gcry_err_code_t and gcry_err_source_t.
   The new functions are gcry_err_code, gcry_err_source, gcry_error,
   gcry_err_make, gcry_error_from_errno, gcry_err_make_from_errno,
   gcry_err_code_from_errno, gcry_err_code_to_errno,
   gcry_strsource.

 * New cipher: Twofish128; New cipher modes: CTR, CBC-MAC.

 * New message digests: SHA384, SHA512, CRC-32, CRC32-RFC1510,
   CRC-24-RFC2440.

 * For RSA decrypt operations, RSA blinding is used automatically to
   prevent the leaking of timing informationen, that can be used to
   compute the secret key, in case the operations can be measured
   precisely.  This mode of operation can be disabled with a special
   flag.

 * gcry_sexp_canon_len does not use a `historically encoded' error
   code anymore.
