Version 0.5
===========

• ABI changed due to changes in specification. API is preserved. Please
recompile your applications.

• This release has not been tested on real system because devoloper has not
obtained new testing account yet. But he believes library works. Testers are
welcome.

• Delivery events 5, 10, 11, 12, and 13 are recognized now.

• GetMessageAuthor service implemented as get_message_sender() function.

• New isds_envelope member `dmPublishOwnID' added. It allows sender to reveal
his natural name to recipient on sending a message.

• isds_GetDataBoxUsers() can return empty list of users now.

• New document types recognised. MIME types of Software602 forms have been
changed to reflect IANA registry.

• Credential for testing account removed from documentation and code. Owner of
ISDS removed all testing accounts, testers must request for new account and
must agree with new rules including keeping credentials in secret and
non-disclosuring found bugs in ISDS. Example clients and on-line tests read
credentials from environment and central file in build root direcotory. See
README for more details.

• Errors from libxml2 parser are captured by libisds log system as ILF_XML
facility and at ILL_ERROR level. Application can get them by standard library
interface.

• Library can be compiled without support for network operation by passing
`--without-libcurl' option to configure script. All functions dependent on
network remain available and will return IE_NOTSUP return code.

• Dead variables removed to pass compilation by GCC 4.6 in strict mode.

• Prepare test environment to pass without ~/.gnupg directory. Packagers can
remove the hack from their packages now.

Version 0.4
===========

• This version breaks ABI because of ISDS specification change. Please adapt
your application where affected functions are called.

• ABI change: isds_get_password_expiration() will return NULL if password never
expires. Adjust your application to cope with NULL pointer on IE_SUCCESS.

• ABI change: isds_add_box() has new credentials_delivery parameter to request
for on-line credentials delivery and to receive token for that.

• ABI change: isds_add_user() has new credentials_delivery parameter to
request for on-line credentials delivery and to receive token for that.

• ABI change: isds_reset_password() has different arguments to request for
on-line credentials delivery and to receive token for that.

• ABI change: deprecated functions isds_set_tls() and
isds_set_mime_type_normalization() removed. Use isds_set_opt() instead.

• SOAP Fault error message is passed to application via isds_long_message().

• New function isds_get_list_of_sent_message_state_changes() implements
GetMessageStateChanges service. It returns list of message status changes in
requested time interval.

• New function isds_get_box_list_archive() implements GetDataBoxList service.
It returns ZIP archive with comma separate list of boxes. Different types of
lists can be requested. Only type `UPG' is available to public.

• New function isds_activate() implements Activate service.

• New delivery state EV0 is recognized as EVENT_ENTERED_SYSTEM isds_event_type.

• `tsr' document name suffix is recognized as time stamp file type.

• New function isds_pki_credentials_free() to deallocate isds_pki_credentials
structure.

• ISO time string parser fixed (negative or no time zone offset).

• All tests can run in parallel now.

• Lot of internal tests added. Funny color output now.

Version 0.3.1
=============

• Add `server' directory to distribution tar balls because example messages
are needed for some tests.

Version 0.3
===========

• This library breaks API because of new features and changes in ISDS.

• This library version covers complete ISDS specification as released on
2010-05-23.

• Support for XML documents added. Use isds_document.is_xml to distinguish
between binary and XML document types. Because XML node list
(isds_document.xml_node_list) is used to describe XML document, your
application must link to libxml2 library too since now. Please note this
feature has not been heavily tested and that the interface is a little tricky
(regarding memory allocation). See client/sendxmldoc.c and
client/loadsentmessagewithxmldocuments.c examples for hints how to use it.

• Box creation (isds_add_box()) supports requesting for token. This
functionality is not covered by specification as it's not implemented on
server side yet.

• Message authenticity verification through new web service
AuthenticateMessage (isds_authenticate_message()) is supported. This function
sends a signed message encapsulated in CMS to ISDS where the system resolves
originality of the message.

• isds_envelope->dmType is input/output now. The one letter value is
transferred while sending new message. However ISDS ignores this option as
semantic is not defined yet.

• isds_envelope->timestamp is optional now. Some ISDS services can return
message without time stamp as can do not exist yet.

• Cookie-tracked session authentication changed to stateless. That means
password is transmitted to server on each request. Password is cached by
libcurl library until connection gets closed. Also different server locators
for non-certificate and certificate client authentication emerged. Old log-in
method will be canceled on 2010-07-01. Old libisds versions become useless.
Upgrade is strongly recommended.

• Static and out-of-source directory compilation is supported now.

• New function isds_normalize_mime_type(): translates file name extension to
MIME type (because official ISDS client is broken). This can be globally
enabled by isds_set_opt().

• Context parameters can be set by isds_set_opt(): TLS options (isds_set_tls()
is deprecated now), MIME type normalization (new: mangle document MIME type
in incoming messages into more reasonable values).

• Deprecated functions removed: isds_load_received_message(),
isds_log_signed_message().

• isds_DbUserInfo.caState added (country of contact address).

• isds_get_delivery_info() fixed to produce standard raw representation of
delivery details that can be loaded by isds_load_delivery() back.

• New function guess_raw_type(): detects type of supported message and
delivery details formats. Detected format can be supplied to
isds_load_message(). This way, application can automagically load and parse
any supported format.

• libcurl debug messages are caught by libisds and redirected to library
logger (ILF_HTTP facility).

Version 0.2.1
=============

• Libs value in libisds.pc pkg-config module fixed.

Version 0.2
===========

• X.509 client certificate authentication is supported (but not tested yet).
Underlying HTTPS cURL library supports OpenSSL, GnuTLS and NSS cryptographic
back ends currently.

Current legislation requires to use cryptographic module with unexportable
private key. I've tested ASEKey produced by Athena Smartcard Solution
with OpenSSL back end successfully (a patch for curl-7.20.0 is required).

Example code client/certauth.c and server/tls/peer server and CA, server and
client cryptographic material are bundled. 

• Application can pass CRL PEM file to cryptographic library.

• Library offers pkg-config integration. Application build scripts can check
`libisds' pkg-config module and use PKG_CHECK_MODULES() m4 macro.

• Application can get dynamic string describing library version and its
dependencies at run-time (isds_version()).

• API changed and is not backward compatible. Please adjust and recompile your
applications.

• Library tests have been splitted to off-line (--enable-test) and on-line
(--enable-online-test) tests. On-line tests can not be compiled without
off-line tests. All tests are switched off by default.

• Server base URL for isds_login() does not contain path anymore. Application
must supply schema and hostname only (e.g. https://localhost/). Undefined base
URL will be interpreted as official ISDS locator.

• Base URLs of official ISDS server (isds_locator) and testing ISDS server
(isds_testing_locator) are provided by library. Application can offer them as
default choices to the user.

• Documents can be submitted for authorize conversion into Czech POINT system
(czp_convert_document(), requires specific isds_ctx).

• Application can catch all global log messages and redirect them wherever it
needs.

Version 0.1
===========

• This is first public release. Whole ISDS 2010-01-22 specification is covered
except: XML documents, X.509 authentication
