gsoap was updated to release 2.8.102:

* Improved HTTP digest authentication plugin to cover
  additional HTTP methods.

Update to release 2.8.101:

* Fix read beyond end-of-buffer in soap_accept
* Other unspecified improvements

Update to release 2.8.100:

* Improved proxy connectivity on the client side to handle bearer
  authentication.
* Improved soapcpp2 handling of the `#module` directive.
* Fixed an MTOM flag clearing issue hampering MTOM usability.

Update to release 2.8.99:

* Improved performance of the soapcpp2 tool.
* Improved proxy connectivity on the client side with
  `soap::proxy_host`, `soap::proxy_port`, and NTLM, to maintain
  HTTP headers, e.g. `soap::http_content` and
  `soap::http_extra_header`.
* Fixed a bug in HTTP cookie handling when the optional
  `-DWITH_COOKIES` flag is used. Note that cookie support is
  disabled by default or has no effect when deploying robust
  services with the gSOAP Apache modules and ISAPI extensions
  that handle cookies differently.

Update to release 2.8.98:

* Updated the WS-Security and WS-Trust APIs that use SAML with
  higher precision timestamps in microseconds, using the
  `custom/struct_timeval.h` serializer for `xsd__dateTime`. The
  WS-Security and WS-Trust updates require compiling and
  linking with `custom/struct_timeval.c`.
* Fixed an issue with soapcpp2 code generation of `wchar_t*`
  serializers when combined with a custom serializer with base
  type `wchar_t*`, i.e. when `extern typedef wchar_t* name` is
  declared.
* Fixed an issue with soapcpp2 code generation when an element
  tag names starts with an underscore and the element is
  namespace qualified.

Update to release 2.8.97:

* Fixed wsdl2h processing of schemas with a cyclic schema
  `<xs:include>` that may cause wsdl2h to hang when schemas
  have no `targetNamespace` attribute.
* Improved wsdl2h code generation of unqualified types and
  names defined in imported schemas (with `<xs:import>`) when
  these schemas have no `targetNamespace`. Use wsdl2h option
  `-z10` or lesser to revert to the code generation behavior of
  versions prior to 2.8.97.

Update to release 2.8.96

* Improved `soap_check_mime_attachments()` and
  `soap_recv_mime_attachment()` functions and documentation,
  ensure proper close when MIME/MTOM errors occur.

Update to release 2.8.95

* Upgraded smdevp.c to replace deprecated OpenSSL API function.
* Updated WS-Security WSSE plugin, documentation, and demo.
* Improved soapcpp2 execution speed to generate WSDL and
  XSD files.

Update to release 2.8.94

* Fixed a wsdl2h issue that caused it to omit names for local
  simpleType restrictions in the generated `enum` types of
  struct/class members; improved soapcpp2 to avoid `enum`
  symbol numbering clashes in the generated source code.
* Removed unnecessary namespace prefixes from some class/struct
  members in the source code generated by wsdl2h in a specific
  case, to prevent XML validation issues.
* Added wsdl2h option `-z9` for backward compatibility of
  2.8.94 and greater to versions 2.8.93 and lesser, which
  reverts the namespace change.

Update to release 2.8.93

* Fixed a wsdl2h schema import/include issue when a `./` occurs
  in schemaLocation` and schema import/include dependencies are
  cyclic, causing wsdl2h to not be able to locate and read
  schema files.
* Removed empty substitutionGroup and duplicate
  substitutionGroup elements in wsdl2h-generated
  `SUBSTITUTIONS` sections.

Update to release 2.8.92

* Fixed soapcpp2-generated call to `soap_DELETE` for REST
  DELETE operations.

Update to new upstream release 2.8.91

* Correction to fix soapcpp2 2.8.90 `-z#` flag enforcement
  problem.

Update to new upstream release 2.8.89

* Added wsdl2h option `-X` to do not qualify part names in
  order to disambiguate document/literal wrapped patterns (as
  the other choice to disambiguate instead of the default
  qualification with schema namespaces).
* Added wsdl2h option `-z8` for backward compatibility with
  2.8.74 and earlier: don't qualify part names to disambiguate
  doc/lit wrapped patterns and revert to the old wrapper
  class/struct naming used for `xs:anyType` inheritance.

Update to new upstream release 2.8.87

* Added `soap::connect_retry` to specify a number of retries at
  the client side when connecting to a server fails, with
  exponential backoff of 2^n seconds between retries.
  Zero by default, meaning no retries.
* Added `soap::client_addr_ipv6` to optionally specify a IPv6 or
  host address to bind to at the client side, when the
  destination is a IPv6 server. Otherwise uses
  `soap::client_addr` to bind.


Update to new upstream release 2.8.86

* Added `soap::client_addr` string to specify a IPv4 or IPv6 or
  a host address to bind to before connecting. This can be used
  at the client side to bind to an address before connecting to
  a server endpoint, similar to `soap::client_port`.
* Fixed wsdl2h compilation issue with C++17.
* Fixed a problem with the `SOAP_SSL_DEFAULT` settings
  parameter used with `soap_ssl_client_context` and
  `soap_ssl_server_context` that may lead to a weaker setting
  than specified.


Update to new upstream release 2.8.83

* Added wsdl2h optimization options `-Ow2`, `-Ow3`, and `-Ow4`
  to optimize the generated source code by schema slicing,
  while retaining all derived extensions of base types.
* Added wsdl2h option `-Q` to make `xsd__anySimpleType` equal
  to `xsd__anyType` to use as the base type for derived types,
  so that elements of type `xsd:anySimpleType` can be
  serialized with a derived type, using inheritance in C++ and
  by using simulated inheritance in C using wsdl2h option `-F`.
* Updated wsdl2h options `-p` and `-F` to generate additional
  wrappers for primitive types that aren't XSD primitive types,
  such as `SOAP-ENC:base64`.
* Improved wsdl2h output for the infrequently-used
  `SOAP-ENC:Array` type.
* Fixed an issue with soapcpp2 option `-A` that resulted in
  error 13 `SOAP_NO_METHOD`.


Update to new upstream release 2.8.81

* Added the ability to specify `nullptr` web service operation
  arguments, similar to `nullptr` struct and class members.
  This enables `xs:nillable="true"` elements corresponding to
  web service operation arguments.
* Updated wsdl2h `import schemaLocation` logic to handle
  relative paths.
* Updated DOM API for embedded serializable data types:
  `SOAP_DOM_ASIS` removes XML namespace bindings (`xmlns`) from
  the XML output of the embedded data type, which are normally
  added to ensure namespace prefixes are always valid.
  `SOAP_DOM_ASIS` requires the DOM to specify the namespace
  bindings explicitly.

Update to new upstream release 2.8.80

* Updated to remove GCC 8.2 warnings.
* Improved wsdl2h handling of relative file paths.

Update to new upstream release 2.8.79

* Fixed a bug in wsdl2h option `-c` for C source code output,
  resulting in a missing `*` pointer for `_XML __any` member
  declaration when declared after the `$ int __size` array size
  member. The bug may lead to validation errors in extensible
  types when extra elements are present in the XML payload
  received. The fix produces the correct `_XML *__any` member
  declaration.

Update to new upstream release 2.8.78

* wsdl2h: WSDL and schema imports of files on relative paths:
  file name without path or file name with path stating with
  ../ are considered relative locations with respect to the
  current WSDL and schema that is importing, otherwise imported
  files are considered relative to the directory in which
  wsdl2h is run (the `-I` option can be used to change that
  location).
* wsdl2h: to display warnings for invalid complexType and
  simpleType extensions/restrictions but generates valid code
  in such cases by inference, the update also fixes a valid
  extension case.
* Fixed compilation error for soapcpp2 options `-i` and `-j`
  caused by special case with empty input arguments to service
  operations.
* Added jsoncpp new option `-k`.


Update to new upstream release 2.8.75

* Added wsdl2h option `-F` to add transient pointer members to
  structs to simulate type derivation with structs in C.
* Added wsdl2h option `-L` to generate less documentation in
  interface header files.
* Added `WITH_NOEMPTYNAMESPACES` compile-time flag to disable
  `xmlns=""`, this is intended for backward compatibility with
  old XML parsers and old gSOAP versions that do not support
  `xmlns=""` empty default namespaces.
* Updated wsdl2h option `-D` to make attributes with fixed
  values pointer members in structs and classes, not just
  attributes with default values.
* Updated wsdl2h option `-f` to flatten C++ class hierarchy by
  removing inheritance. This option removes support for type
  derivation with `xsi:type` in XML.
* Updated soapcpp2 to split up the `soap_call_ns__webmethod`
  functions into new `soap_send_ns__webmethod` and
  `soap_recv_ns__webmethod` functions called by
  `soap_call_ns__webmethod`. The new functions can be used for
  asynchronous messaging.
* Updated soapcpp2 option `-j` to call `destroy()` in
  destructor to deallocate managed heap data.
* Updated call to OpenSSL `ERR_remove_state` (deprecated) by
  `ERR_remove_thread_state`.
* Fixed a bug in HTTP cookie handling by the engine. HTTP
  cookies are disabled by default, but enabled with the
  `-DWITH_COOKIES` compile-time flag or when using the C/C++
  `libgsoapck`/`libgsoapck++` and `libgsoapssl`/`libgsoapssl++`
  libraries.


Update to new upstream release 2.8.74:

* Fixed an issue with MIME/MTOM attachment sending when the
  HTTP-digest plugin is used or when compression is enabled,
  returning incorrect `SOAP_EOM` error (i.e. not caused by
  out-of-memory). The problem had been introduced in 2.8.70.


Update to new upstream release 2.8.73

* Improved `soap_ssl_accept()` timeout settings to improve the
  performance of gSOAP stand-alone HTTPS servers.
* Renamed `soap_get_http_body()` to `soap_http_get_body()` to
  avoid name clashes with soapcpp2-generated `soap_get_T`
  functions.
* Renamed `soap_get_form()` to `soap_http_get_form()` to avoid
  name clashes with soapcpp2-generated `soap_get_T` functions.
* Renamed `soap_get_mime_attachment()` to
  `soap_recv_mime_attachment()` to avoid name clashes with
  soapcpp2-generated `soap_get_T` functions.
* Renamed `soap_get_stats()` to `soap_http_get_stats()` of the
  httpget plugin to avoid name clashes with soapcpp2-generated
  `soap_get_T` functions.
* Renamed `soap_get_logging_stats()` to `soap_logging_stats()`
  of the logging plugin to avoid name clashes with
  soapcpp2-generated `soap_get_T` functions.
* Moved `soap_http_get_form()`, `soap_query()`,
  `soap_query_key()`, and `soap_query_val()` functions from the
  httpget and httpform plugin APIs to the stdsoap2.c[pp]
  library API. No project rebuilds should be necessary when
  using these plugins with this upgrade.


Update to new upstream release 2.8.72

* Improved the HTTP GET `http_get` and HTTP POST `http_post`
  plugins, handling of a HTTP POST request that has an empty
  body is now supported.
* Updated user guide, corrected `soap_rand_uuid` description:
  string returned is stored in a temporary buffer, not stored
  in managed memory.
* Fixed spurious constant initialization problem for `enum`
  types in soapcpp2-generated code, the problem was introduced
  with soapcpp2 2.8.71 C/C++ grammar expansion.
* Fixed a CURL plugin issue that prevented PUT and DELETE
  methods to work properly.


Update to new upstream release 2.8.71

* Added TLSv1.3 support with OpenSSL 1.1.1.
* Added HTTP PATCH support.
* Updated SSL/TLS options for `soap_ssl_client_context` and
  `soap_ssl_server_context` to allow combinations of
  `SOAP_TLSv1_0`, `SOAP_TLSv1_1`, `SOAP_TLSv1_2`,
  `SOAP_TLSv1_3` protocols (v1.3 only available with OpenSSL
  1.1.1 and greater), a change from the single TLS protocol
  flag.
* Fixed soapcpp2 code generation issue for single- and
  multi-dimensional fixed-size arrays.


Update to new upstream release 2.8.70

* Updated `typemap.dat` for ONVIF and upgraded `wsdd10.h`
  (WS-Discovery 1.0 with WS-Addressing 2004/08) to `wsdd5.h`
  (WS-Discovery 1.0 with WS-Addressing 2005/08).
* Fixed a deserialization issue with Qt `QString` used in a
  wrapper class (as `__item` member), when the wrapper class is
  used in a container, such as `std::vector`.


Update to new upstream relesae 2.8.69

* Improved `xs:redefine` processing, fixing the remaining
  "circular group reference" warnings.
* Improved XML sample message generation.


Update to new upstream release 2.8.67

* Changed `typemap.dat` to disable `xsd__duration` custom
  serializer by default, meaning that `xsd__duration` is
  serialized as a string by default.
* Fixed an issue where the 64-bit integer types `LONG64` and
  `ULONG64` and their serializers would be downcast to to 32-bit
  when compiling C code with newer GCC versions, due to
  `__STDC_VERSION__` no longer being defined by the compiler.
