Noteworthy changes in version 0.4.1 (unreleased) ------------------------------------------------ * GPGME_ATTR_IS_SECRET is not anymore representable as a string. * gpgme_op_verify and gpgme_op_decrypt_verify don't return a status summary anymore. Use gpgme_get_sig_status to retrieve the individual stati. * GpgmeIOCb changed from a void function to a function returning a GpgmeError value. However, it will always return 0, so you can safely ignore the return value. * A new I/O callback event GPGME_EVENT_START has been added. The new requirement is that you must wait until this event until you are allowed to call the I/O callback handlers previously registered for this context operation. Calling I/O callback functions for this context operation before the start event happened is unsafe because it can lead to race conditions in a multi-threaded environment. * The idle function feature has been removed. It was not precisely defined in a multi-threaded environment and is obsoleted by the user I/O callback functions. If you still need a simple way to call something while waiting on one or multiple asynchronous operations to complete, don't set the HANG flag in gpgme_wait (note that this will return to your program more often than the idle function did). * gpgme_wait can return NULL even if hang is true, if an error occurs. In that case *status contains the error code. * gpgme_get_engine_info was radically changed. Instead an XML string, an info structure of the new type GpgmeEngineInfo is returned. This makes it easier and more robust to evaluate the information in an application. * The new function gpgme_get_protocol_name can be used to convert a GpgmeProtocol value into a string. * The GpgmePassphraseCb type now returns a GpgmeError value, and returns the password string in a new parameter. The gpgme_cancel function has been removed, just return GPGME_Canceled in the passphrase callback directly. * The status of a context operation is not checked anymore, so the errors GPGME_Busy and GPGME_No_Request can not occur anymore. * For clarity and better reusability, the error codes GPGME_No_Recipients, GPGME_Invalid_Recipient and GPGME_No_Passphrase have been renamed to GPGME_No_UserID, GPGME_Invalid_UserID and GPGME_Bad_Passphrase resp. * The FPR argument to gpgme_op_genkey was removed. Instead, use the gpgme_op_genkey_result function to retrieve a GpgmeGenKeyResult pointer to a structure which contains the fingerprint. This also works with gpgme_op_genkey. The structure also provides other information about the generated keys. So, instead: char *fpr; err = gpgme_op_genkey (ctx, NULL, NULL, &fpr); if (!err && fpr) printf ("%s\n", fpr); you should now do: GpgmeGenKeyResult result; err = gpgme_op_genkey (ctx, NULL, NULL); if (!err) { result = gpgme_op_genkey_result (ctx); if (result->fpr) printf ("%s\n", result->fpr); } * The new gpgme_op_import_result function provides detailed information about the result of an import operation in GpgmeImportResult and GpgmeImportStatus objects. Thus, the gpgme_op_import_ext variant is deprecated. * Interface changes relative to the 0.4.0 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GpgmeIOCb CHANGED: Return type from void to GpgmeError.

Noteworthy changes in version 0.3.12 (2002-10-15) ------------------------------------------------- * Fixed some bux with key listings. * The development has been branched to clean up some API issues. This 0.3 series will be kept for compatibility reasons; so do don't expect new features. Noteworthy changes in version 0.3.11 (2002-09-20) ------------------------------------------------- * Bug fixes. Noteworthy changes in version 0.3.10 (2002-09-02) ------------------------------------------------- * Setting the signing keys for the CMS protocol does now work. * The signers setting is honoured by gpgme_op_edit. Noteworthy changes in version 0.3.9 (2002-08-21) ------------------------------------------------ * A spec file for creating RPMs has been added. * An experimental interface to GnuPG's --edit-key functionality is introduced, see gpgme_op_edit. * The new gpgme_import_ext function provides a convenient access to the number of processed keys. * Interface changes relative to the 0.3.8 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GpgmeStatusCode NEW GpgmeEditCb NEW gpgme_op_edit_start NEW gpgme_op_edit NEW gpgme_op_import_ext NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 0.3.8 (2002-06-25) ------------------------------------------------ * It is possible to use an outside event loop for the I/O to the crypto engine by setting the I/O callbacks with gpgme_set_io_cbs. * Interface changes relative to the 0.3.6 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GpgmeIOCb NEW GpgmeRegisterIOCb NEW GpgmeRemoveIOCb NEW GpgmeEventIO NEW GpgmeEventIOCb NEW struct GpgmeIOCbs NEW gpgme_set_io_cbs NEW gpgme_get_io_cbs NEW GPGME_ATTR_ERRTOK NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 0.3.7 (2002-06-04) ------------------------------------------------ * GPGME_ATTR_OTRUST is implemented now. * A first step toward thread safeness has been achieved, see the documentation for details.

Instead of always returning GPGME_SIG_STATUS_GOOD, the functions new codes for expired signatures. 2 new functions may be used to retrieve more detailed information like the signature expiration time and a validity information of the key without an extra key looking. * The current passphrase callback and progress meter callback can be retrieved with the new functions gpgme_get_passphrase_cb and gpgme_get_progress_cb respectively. * Interface changes relative to the 0.3.5 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gpgme_get_passphrase_cb NEW gpgme_get_progress_cb NEW GpgmeDataEncoding NEW gpgme_data_set_encoding NEW gpgme_data_get_encoding NEW GPGME_SIG_STAT_GOOD_EXP NEW GPGME_SIG_STAT_GOOD_EXPKEY NEW gpgme_op_verify CHANGED: Returns more status codes. GPGME_ATTR_SIG_STATUS NEW gpgme_get_sig_string_attr NEW gpgme_get_sig_ulong_attr NEW gpgme_get_protocol NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 0.3.5 (2002-04-01) ------------------------------------------------ * gpgme_op_encrypt can be called with RECIPIENTS being 0. In this case, symmetric encryption is performed. Note that this requires a passphrase from the user. * More information is returned for X.509 certificates. * Interface changes relative to the 0.3.4 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gpgme_op_encrypt EXTENDED: Symmetric encryption possible ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 0.3.4 (2002-03-04) ------------------------------------------------ * gpgme_op_encrypt does now fail with GPGME_Invalid_Recipients if some recipients have been invalid, whereas earlier versions succeeded in this case. The plaintext is still encrypted for all valid recipients, so the application might take this error as a hint that the ciphertext is not usable for all requested recipients. Information about invalid recipients is available with gpgme_get_op_info. * gpgme_op_verify now allows to pass an uninitialized data object as its plaintext argument to check for normal and cleartext signatures. The plaintext is then returned in the data object. * New interfaces gpgme_set_include_certs and gpgme_get_include_certs to set and get the number of certifications to include in S/MIME signed messages. * New interfaces gpgme_op_encrypt_sign and gpgme_op_encrypt_sign_start to encrypt and sign a message in a combined operation. * New interface gpgme_op_keylist_ext_start to search for multiple patterns. * gpgme_key_get_ulong_attr supports the GPGME_ATTR_EXPIRE attribute. * Interface changes relative to the 0.3.3 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gpgme_op_encrypt CHANGED: Can fail with GPGME_Invalid_Recipients gpgme_op_verify EXTENDED: Accepts uninitialized text argument gpgme_key_get_ulong_attr EXTENDED: Supports GPGME_ATTR_EXPIRE gpgme_set_include_certs NEW gpgme_get_include_certs NEW gpgme_op_encrypt_sign NEW gpgme_op_encrypt_sign_start NEW gpgme_op_keylist_ext_start NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 0.3.3 (2002-02-12) ------------------------------------------------ * Fix the Makefile in jnlib. * Fix the test suite (hopefully). It should clean up all its state with `make check' now. Noteworthy changes in version 0.3.2 (2002-02-10) ------------------------------------------------ * Remove erroneous dependency on libgcrypt in jnlib. Noteworthy changes in version 0.3.1 (2002-02-09) ------------------------------------------------ * There is a Texinfo manual documenting the API. * The gpgme_set_keylist_mode function returns an error, and changed its meaning. It is no longer usable to select between normal and fast mode (newer versions of GnuPG will always be fast), but selects between local keyring, remote keyserver, or both. For this, two new macros are defined, GPGME_KEYLIST_MODE_LOCAL and GPGME_KEYLIST_MODE_EXTERN. To make it possible to modify the current setting, a fucntion gpgme_get_keylist_mode was added to retrieve the current mode. * gpgme_wait accepts a new argument STATUS to return the error status of the operation on the context. Its definition is closer to waitpid() now than before. * The LENGTH argument to gpgme_data_new_from_filepart changed its type from off_t to the unsigned size_t. * The R_HD argument to the GpgmePassphraseCb type changed its type from void* to void**. * New interface gpgme_op_trustlist_end() to match gpgme_op_keylist_end(). * The CryptPlug modules have been renamed to gpgme-openpgp and gpgme-smime, and they are installed in pkglibdir by `make install'. * An idle function can be registered with gpgme_register_idle(). * The GpgSM backend supports key generation with gpgme_op_genkey(). * Interface changes relative to the 0.3.0 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gpgme_data_new_from_filepart CHANGED: Type of LENGTH is size_t. GpgmePassphraseCb CHANGED: Type of R_HD is void **. gpgme_wait CHANGED: New argument STATUS. gpgme_set_keylist_mode CHANGED: Type of return value is GpgmeError. The function has a new meaning! gpgme_get_keylist_mode NEW GPGME_KEYLIST_MODE_LOCAL NEW GPGME_KEYLIST_MODE_EXTERN NEW gpgme_op_trustlist_next NEW GpgmeIdleFunc NEW gpgme_register_idle NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 0.3.0 (2001-12-19) ------------------------------------------------ * New interface gpgme_set_protocol() to set the protocol and thus the crypto engine to be used by the context. Currently, the OpenPGP and the CMS protocols are supported. They are specified by the new preprocessor symbols GPGME_PROTOCOL_OpenPGP and GPGME_PROTOCOL_CMS. A new context uses the OpenPGP engine by default. * gpgme_get_engine_info() returns information for all crypto engines compiled into the library. The XML format has changed. To reliably get the version of a crypto engine, the tag after the appropriate tag has to be looked for. * New interface gpgme_engine_check_version(), obsoleting gpgme_check_engine(). Check the version of all engines you are supporting in your software. * GpgmeKey lists the user ids in the order as they are returned by GnuPG, first the primary key with index 0, then the sub-user ids. * New operation gpgme_op_decrypt_verify() to decrypt and verify signatures simultaneously. * The new interface gpgme_op_keylist_end() terminates a pending keylist operation. A keylist operation is also terminated when gpgme_op_keylist_next() returns GPGME_EOF. * GPGME can be compiled without GnuPG being installed (`--with-gpg=PATH'), cross-compiled, or even compiled without support for GnuPG (`--without-gpg'). * GPGME can be compiled with support for GpgSM (GnuPG for S/MIME, `--with-gpgsm=PATH'). It is enabled by default if the `gpgsm' is found in the path, but it can also be compiled without support for GpgSM (`--without-gpgsm'). * CryptPlug modules for GPGME are included and can be enabled at configure time (`--enable-gpgmeplug'). There is one module which uses the GnuPG engine (`gpgmeplug') and one module which uses the GpgSM engine (`gpgsmplug'). * Interface changes relative to the latest 0.2.x release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gpgme_key_get_as_xml CHANGED: Sub-user ids reversed in order. gpgme_key_get_string_attr CHANGED: User ids reversed in order. gpgme_key_get_ulong_attr CHANGED: User ids reversed in order. gpgme_get_engine_info CHANGED: New format, extended content. gpgme_engine_check_version NEW gpgme_decrypt_verify_start NEW gpgme_decrypt_verify NEW gpgme_op_keylist_next NEW gpgme_set_protocol NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 0.2.3 (2001-09-17) ------------------------------------------------ * New function gpgme_get_op_info which can be used to get the micalg parameter needed for MOSS. * New functions gpgme_get_armor and gpgme_get_textmode. * The usual bug fixes and some minor functionality improvements. * Added a simple encryption component for MS-Windows; however the build procedure might have some problems. Noteworthy changes in version 0.2.2 (2001-06-12) ------------------------------------------------ * Implemented a key cache. * Fixed a race condition under W32 and some other bug fixes. Noteworthy changes in version 0.2.1 (2001-04-02) ------------------------------------------------ * Changed debug output and GPGME_DEBUG variable (gpgme/debug.c) * Handle GnuPG's new key capabilities output and support revocation et al. attributes * Made the W32 support more robust.
