1 Noteworthy changes in version 0.4.3 (unreleased)
2 ------------------------------------------------
4 * gpgme_get_key fails with GPG_ERR_AMBIGUOUS_NAME if the key ID
5 provided was not unique, instead returning the first matching key.
7 * Interface changes relative to the 0.4.3 release:
8 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
9 gpgme_get_key CHANGED: Fails correctly if key ID not unique.
10 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
13 Noteworthy changes in version 0.4.2 (2003-07-30)
14 ------------------------------------------------
16 * Allow gpg-error to be in non-standard place when linking the test suite.
18 * Configure will fail now if gpg-error can not be found.
20 * Fixed initialized memory backed data objects for writing, which
21 caused the test program to crash (but only on Mac OS, surprisingly).
23 * Eliminate use of C99 constructs.
25 * Small improvements to the manual.
28 Noteworthy changes in version 0.4.1 (2003-06-06)
29 ------------------------------------------------
31 This is the release that 0.4.0 should have been. There are many
32 interface changes, please see below for the details. The changes are
33 sometimes the result of new functionality, but more often express a
34 paradigm shift. Others are an overdue cleanup to get GPGME in line
35 with the GNU coding standards and to make the interface more
36 self-consistent. Here is an overview on the changes:
38 All types have been renamed to conform to the GNU coding standards,
39 most of the time by keeping the whole name in lowercase and inserting
40 underscores between words.
42 All operations consistently only accept input parameters in their
43 invocation function, and return only an error code directly. Further
44 information about the result of the operation has to be retrieved
45 afterwards by calling one of the result functions. This unifies the
46 synchronous and the asynchronous interface.
48 The error values have been completely replaced by a more
49 sophisticated model that allows GPGME to transparently and accurately
50 report all errors from the other GnuPG components, irregardless of
51 process boundaries. This is achieved by using the library
52 libgpg-errors, which is shared by all GnuPG components. This library
53 is now required for GPGME.
55 The results of all operations are now provided by pointers to C
56 structs rather than by XML structs or in other ways.
58 Objects which used to be opaque (for example a key) are now pointers
59 to accessible structs, so no accessor functions are necessary.
61 Backward compatibility is provided where it was possible without too
62 much effort and did not collide with the overall sanitization effort.
63 However, this is only for ease of transition. NO DEPRECATED FUNCTION
64 OR DATA TYPE IS CONSIDERED A PART OF THE API OR ABI AND WILL BE
65 DROPPED IN THE FUTURE WITHOUT CHANGING THE SONAME OF THE LIBRARY.
66 Recommendations how to replace deprecated or removed functionality
67 can be found within the description of each change.
69 What follows are all changes to the interface and behaviour of GPGME
72 * If gpgme.h is included in sources compiled by GCC 3.1 or later,
73 deprecated attributes will warn about use of obsolete functions and
74 type definitions. You can suppress these warnings by passing
75 -Wno-deprecated-declarations to the gcc command.
77 * The following types have been renamed. The old types are still
78 available as aliases, but they are deprecated now:
81 GpgmeData gpgme_data_t
82 GpgmeError gpgme_error_t
83 GpgmeDataEncoding gpgme_data_encoding_t
84 GpgmeSigStat gpgme_sig_stat_t
85 GpgmeSigMode gpgme_sig_mode_t
86 GpgmeAttr gpgme_attr_t
87 GpgmeValidity gpgme_validity_t
88 GpgmeProtocol gpgme_protocol_t
90 GpgmePassphraseCb gpgme_passphrase_cb_t
91 GpgmeProgressCb gpgme_progress_cb_t
92 GpgmeIOCb gpgme_io_cb_t
93 GpgmeRegisterIOCb gpgme_register_io_cb_t
94 GpgmeRemoveIOCb gpgme_remove_io_cb_t
95 GpgmeEventIO gpgme_event_io_t
96 GpgmeEventIOCb gpgme_event_io_cb_t
97 GpgmeIOCbs gpgme_io_cbs
98 GpgmeDataReadCb gpgme_data_read_cb_t
99 GpgmeDataWriteCb gpgme_data_write_cb_t
100 GpgmeDataSeekCb gpgme_data_seek_cb_t
101 GpgmeDataReleaseCb gpgme_data_release_cb_t
102 GpgmeDataCbs gpgme_data_cbs_t
103 GpgmeTrustItem gpgme_trust_item_t
104 GpgmeStatusCode gpgme_status_code_t
106 * gpgme_error_t is now identical to gpg_error_t, the error type
107 provided by libgpg-error. More about using libgpg-error with GPGME
108 can be found in the manual. All error symbols have been removed!
110 * All functions and types in libgpg-error have been wrapped in GPGME.
111 The new types are gpgme_err_code_t and gpgme_err_source_t. The new
112 functions are gpgme_err_code, gpgme_err_source, gpgme_error,
113 gpgme_err_make, gpgme_error_from_errno, gpgme_err_make_from_errno,
114 gpgme_err_code_from_errno, gpgme_err_code_to_errno,
117 * GPGME_ATTR_IS_SECRET is not anymore representable as a string.
119 * GnuPG 1.2.2 is required. The progress callback is now also invoked
120 for encrypt, sign, encrypt-sign, decrypt, verify, and
121 decrypt-verify operations. For verify operations on detached
122 signatures, the progress callback is invoked for both the detached
123 signature and the plaintext message, though.
125 * gpgme_passphrase_cb_t has been changed to not provide a complete
126 description, but the UID hint, passphrase info and a flag
127 indicating if this is a repeated attempt individually, so the user
128 can compose his own description from this information.
130 The passphrase is not returned as a C string, but must be written
131 to a file descriptor directly. This allows for secure passphrase
134 The return type has been changed to gpgme_error_t value. This
135 allowed to remove the gpgme_cancel function; just return
136 the error code GPG_ERR_CANCELED in the passphrase callback directly.
138 * gpgme_edit_cb_t has been changed to take a file descriptor argument.
139 The user is expected to write the response to the file descriptor,
140 followed by a newline.
142 * The recipients interface has been removed. Instead, you use
143 NULL-terminated lists of keys for specifying the recipients of an
144 encryption operation. Use the new encryption flag
145 GPGME_ENCRYPT_ALWAYS_TRUST if you want to override the validity of
146 the keys (but note that in general this is not a good idea).
148 This change has been made to the prototypes of gpgme_op_encrypt,
149 gpgme_op_encrypt_start, gpgme_op_encrypt_sign and
150 gpgme_op_encrypt_sign_start.
152 The export interface has been changed to use pattern strings like
153 the keylist interface. Thus, new functions gpgme_op_export_ext and
154 gpgme_op_export_ext_start have been added as well. Now the
155 prototypes of gpgme_op_export_start and gpgme_op_export finally
158 * gpgme_op_verify and gpgme_op_decrypt_verify don't return a status
159 summary anymore. Use gpgme_get_sig_status to retrieve the individual
162 * gpgme_io_cb_t changed from a void function to a function returning
163 a gpgme_error_t value. However, it will always return 0, so you
164 can safely ignore the return value.
166 * A new I/O callback event GPGME_EVENT_START has been added. The new
167 requirement is that you must wait until this event until you are
168 allowed to call the I/O callback handlers previously registered for
169 this context operation. Calling I/O callback functions for this
170 context operation before the start event happened is unsafe because
171 it can lead to race conditions in a multi-threaded environment.
173 * The idle function feature has been removed. It was not precisely
174 defined in a multi-threaded environment and is obsoleted by the
175 user I/O callback functions. If you still need a simple way to
176 call something while waiting on one or multiple asynchronous
177 operations to complete, don't set the HANG flag in gpgme_wait (note
178 that this will return to your program more often than the idle
181 * gpgme_wait can return NULL even if hang is true, if an error
182 occurs. In that case *status contains the error code.
184 * gpgme_get_engine_info was radically changed. Instead an XML
185 string, an info structure of the new type gpgme_engine_info_t is
186 returned. This makes it easier and more robust to evaluate the
187 information in an application.
189 * The new function gpgme_get_protocol_name can be used to convert a
190 gpgme_protocol_t value into a string.
192 * The status of a context operation is not checked anymore. Starting
193 a new operation will silently cancel the previous one. Calling a
194 function that requires you to have started an operation before without
195 doing so is undefined.
197 * The FPR argument to gpgme_op_genkey was removed. Instead, use the
198 gpgme_op_genkey_result function to retrieve a gpgme_genkey_result_t
199 pointer to a structure which contains the fingerprint. This also
200 works with gpgme_op_genkey_start. The structure also provides
201 other information about the generated keys.
206 err = gpgme_op_genkey (ctx, NULL, NULL, &fpr);
208 printf ("%s\n", fpr);
212 gpgme_genkey_result_t result;
213 err = gpgme_op_genkey (ctx, NULL, NULL);
216 result = gpgme_op_genkey_result (ctx);
218 printf ("%s\n", result->fpr);
221 * The new gpgme_op_import_result function provides detailed
222 information about the result of an import operation in
223 gpgme_import_result_t and gpgme_import_status_t objects.
224 Thus, the gpgme_op_import_ext variant is deprecated.
226 * The new gpgme_op_sign_result function provides detailed information
227 about the result of a signing operation in gpgme_sign_result_t,
228 gpgme_invalid_key_t and gpgme_new_signature_t objects.
230 * The new gpgme_op_encrypt_result function provides detailed
231 information about the result of an encryption operation in
232 a GpgmeEncryptResult object.
234 * The new gpgme_op_decrypt_result function provides detailed
235 information about the result of a decryption operation in
236 a GpgmeDecryptResult object.
238 * The new gpgme_op_verify_result function provides detailed
239 information about the result of an verify operation in
240 a GpgmeVerifyResult object. Because of this, the GPGME_SIG_STAT_*
241 values, gpgme_get_sig_status, gpgme_get_sig_ulong_attr,
242 gpgme_get_sig_string_attr and gpgme_get_sig_key are now deprecated,
243 and gpgme_get_notation is removed.
245 * GpgmeTrustItem objects have now directly accessible data, so the
246 gpgme_trust_item_get_string_attr and gpgme_trust_item_get_ulong_attr
247 accessor functions are deprecated. Also, reference counting is
248 available through gpgme_trust_item_ref and gpgme_trust_item_unref
249 (the gpgme_trust_item_release alias for the latter is deprecated).
251 * Keys are not cached internally anymore, so the force_update argument
252 to gpgme_get_key has been removed.
254 * GpgmeKey objects have now directly accessible data so the
255 gpgme_key_get_string_attr, gpgme_key_get_ulong_attr,
256 gpgme_key_sig_get_string_attr and gpgme_key_sig_get_ulong_attr
257 functions are deprecated. Also, gpgme_key_release is now
258 deprecated. The gpgme_key_get_as_xml function has been dropped.
260 * Because all interfaces using attributes are deprecated, the
261 GpgmeAttr data type is also deprecated.
263 * The new gpgme_op_keylist_result function provides detailed
264 information about the result of a key listing operation in
265 a GpgmeKeyListResult object.
267 * Now that each function comes with its own result retrieval
268 interface, the generic gpgme_get_op_info interface is not useful
271 * The type and mode of data objects is not available anymore.
273 * Interface changes relative to the 0.4.0 release:

563 detailed information like the signature expiration time and a
564 validity information of the key without an extra key looking.
566 * The current passphrase callback and progress meter callback can be
567 retrieved with the new functions gpgme_get_passphrase_cb and
568 gpgme_get_progress_cb respectively.
570 * Interface changes relative to the 0.3.5 release:
571 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
572 gpgme_get_passphrase_cb NEW
573 gpgme_get_progress_cb NEW
574 GpgmeDataEncoding NEW
575 gpgme_data_set_encoding NEW
576 gpgme_data_get_encoding NEW
577 GPGME_SIG_STAT_GOOD_EXP NEW
578 GPGME_SIG_STAT_GOOD_EXPKEY NEW
579 gpgme_op_verify CHANGED: Returns more status codes.
580 GPGME_ATTR_SIG_STATUS NEW
581 gpgme_get_sig_string_attr NEW
582 gpgme_get_sig_ulong_attr NEW
583 gpgme_get_protocol NEW
584 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
586 Noteworthy changes in version 0.3.5 (2002-04-01)
587 ------------------------------------------------
589 * gpgme_op_encrypt can be called with RECIPIENTS being 0. In this
590 case, symmetric encryption is performed. Note that this requires a
591 passphrase from the user.
593 * More information is returned for X.509 certificates.
595 * Interface changes relative to the 0.3.4 release:
596 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
597 gpgme_op_encrypt EXTENDED: Symmetric encryption possible
598 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
600 Noteworthy changes in version 0.3.4 (2002-03-04)
601 ------------------------------------------------
603 * gpgme_op_encrypt does now fail with GPGME_Invalid_Recipients if
604 some recipients have been invalid, whereas earlier versions
605 succeeded in this case. The plaintext is still encrypted for all valid
606 recipients, so the application might take this error as a hint that
607 the ciphertext is not usable for all requested recipients.
608 Information about invalid recipients is available with gpgme_get_op_info.
610 * gpgme_op_verify now allows to pass an uninitialized data object as
611 its plaintext argument to check for normal and cleartext
612 signatures. The plaintext is then returned in the data object.
614 * New interfaces gpgme_set_include_certs and gpgme_get_include_certs
615 to set and get the number of certifications to include in S/MIME
618 * New interfaces gpgme_op_encrypt_sign and gpgme_op_encrypt_sign_start
619 to encrypt and sign a message in a combined operation.
621 * New interface gpgme_op_keylist_ext_start to search for multiple patterns.
623 * gpgme_key_get_ulong_attr supports the GPGME_ATTR_EXPIRE attribute.
625 * Interface changes relative to the 0.3.3 release:
626 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
627 gpgme_op_encrypt CHANGED: Can fail with GPGME_Invalid_Recipients
628 gpgme_op_verify EXTENDED: Accepts uninitialized text argument
629 gpgme_key_get_ulong_attr EXTENDED: Supports GPGME_ATTR_EXPIRE
630 gpgme_set_include_certs NEW
631 gpgme_get_include_certs NEW
632 gpgme_op_encrypt_sign NEW
633 gpgme_op_encrypt_sign_start NEW
634 gpgme_op_keylist_ext_start NEW
635 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
637 Noteworthy changes in version 0.3.3 (2002-02-12)
638 ------------------------------------------------
640 * Fix the Makefile in jnlib.
642 * Fix the test suite (hopefully). It should clean up all its state
643 with `make check' now.
646 Noteworthy changes in version 0.3.2 (2002-02-10)
647 ------------------------------------------------
649 * Remove erroneous dependency on libgcrypt in jnlib.
652 Noteworthy changes in version 0.3.1 (2002-02-09)
653 ------------------------------------------------
655 * There is a Texinfo manual documenting the API.
657 * The gpgme_set_keylist_mode function returns an error, and changed
658 its meaning. It is no longer usable to select between normal and
659 fast mode (newer versions of GnuPG will always be fast), but
660 selects between local keyring, remote keyserver, or both.
661 For this, two new macros are defined, GPGME_KEYLIST_MODE_LOCAL
662 and GPGME_KEYLIST_MODE_EXTERN. To make it possible to modify the
663 current setting, a fucntion gpgme_get_keylist_mode was added to
664 retrieve the current mode.
666 * gpgme_wait accepts a new argument STATUS to return the error status
667 of the operation on the context. Its definition is closer to
668 waitpid() now than before.
670 * The LENGTH argument to gpgme_data_new_from_filepart changed its
671 type from off_t to the unsigned size_t.
673 * The R_HD argument to the GpgmePassphraseCb type changed its type
674 from void* to void**.
676 * New interface gpgme_op_trustlist_end() to match
677 gpgme_op_keylist_end().
679 * The CryptPlug modules have been renamed to gpgme-openpgp and
680 gpgme-smime, and they are installed in pkglibdir by `make install'.
682 * An idle function can be registered with gpgme_register_idle().
684 * The GpgSM backend supports key generation with gpgme_op_genkey().
686 * Interface changes relative to the 0.3.0 release:
687 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
688 gpgme_data_new_from_filepart CHANGED: Type of LENGTH is size_t.
689 GpgmePassphraseCb CHANGED: Type of R_HD is void **.
690 gpgme_wait CHANGED: New argument STATUS.
691 gpgme_set_keylist_mode CHANGED: Type of return value is GpgmeError.
692 The function has a new meaning!
693 gpgme_get_keylist_mode NEW
694 GPGME_KEYLIST_MODE_LOCAL NEW
695 GPGME_KEYLIST_MODE_EXTERN NEW
696 gpgme_op_trustlist_next NEW
698 gpgme_register_idle NEW
699 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
701 Noteworthy changes in version 0.3.0 (2001-12-19)
702 ------------------------------------------------
704 * New interface gpgme_set_protocol() to set the protocol and thus the
705 crypto engine to be used by the context. Currently, the OpenPGP
706 and the CMS protocols are supported. They are specified by the new
707 preprocessor symbols GPGME_PROTOCOL_OpenPGP and GPGME_PROTOCOL_CMS.
708 A new context uses the OpenPGP engine by default.
710 * gpgme_get_engine_info() returns information for all crypto engines
711 compiled into the library. The XML format has changed. To
712 reliably get the version of a crypto engine, the <version> tag
713 after the appropriate <protocol> tag has to be looked for.
715 * New interface gpgme_engine_check_version(), obsoleting
716 gpgme_check_engine(). Check the version of all engines you are
717 supporting in your software.
719 * GpgmeKey lists the user ids in the order as they are returned by
720 GnuPG, first the primary key with index 0, then the sub-user ids.
722 * New operation gpgme_op_decrypt_verify() to decrypt and verify
723 signatures simultaneously.
725 * The new interface gpgme_op_keylist_end() terminates a pending
726 keylist operation. A keylist operation is also terminated when
727 gpgme_op_keylist_next() returns GPGME_EOF.
729 * GPGME can be compiled without GnuPG being installed (`--with-gpg=PATH'),
730 cross-compiled, or even compiled without support for GnuPG
733 * GPGME can be compiled with support for GpgSM (GnuPG for S/MIME,
734 `--with-gpgsm=PATH'). It is enabled by default if the `gpgsm' is found
735 in the path, but it can also be compiled without support for GpgSM
738 * CryptPlug modules for GPGME are included and can be enabled at
739 configure time (`--enable-gpgmeplug'). There is one module which
740 uses the GnuPG engine (`gpgmeplug') and one module which uses the
741 GpgSM engine (`gpgsmplug').
743 * Interface changes relative to the latest 0.2.x release:
744 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
745 gpgme_key_get_as_xml CHANGED: Sub-user ids reversed in order.
746 gpgme_key_get_string_attr CHANGED: User ids reversed in order.
747 gpgme_key_get_ulong_attr CHANGED: User ids reversed in order.
748 gpgme_get_engine_info CHANGED: New format, extended content.
749 gpgme_engine_check_version NEW
750 gpgme_decrypt_verify_start NEW
751 gpgme_decrypt_verify NEW
752 gpgme_op_keylist_next NEW
753 gpgme_set_protocol NEW
754 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
757 Noteworthy changes in version 0.2.3 (2001-09-17)
758 ------------------------------------------------
760 * New function gpgme_get_op_info which can be used to get the micalg
761 parameter needed for MOSS.
763 * New functions gpgme_get_armor and gpgme_get_textmode.
765 * The usual bug fixes and some minor functionality improvements.
767 * Added a simple encryption component for MS-Windows; however the
768 build procedure might have some problems.
771 Noteworthy changes in version 0.2.2 (2001-06-12)
772 ------------------------------------------------
774 * Implemented a key cache.
776 * Fixed a race condition under W32 and some other bug fixes.
779 Noteworthy changes in version 0.2.1 (2001-04-02)
780 ------------------------------------------------
782 * Changed debug output and GPGME_DEBUG variable (gpgme/debug.c)
784 * Handle GnuPG's new key capabilities output and support revocation
787 * Made the W32 support more robust.
