sgcWebSockets 4.5.4

Rad Studio 

Here is the comprehensive list of new features and bug fixes included in sgcWebSockets 4.5.4:

[+] : Improved TLSOptions.Version property, now if the value is tlsUndefined (the default), the client will try to negotiate all possible TLS versions (from TLS 1.3 to TLS 1.0), before this change the TLS 1.0 was selected.
[+] : Improved Amazon AWS IoT Client, new property SignatureV4.SessionToken which must be filled when using temporarity security credentials.
[+] : Improved HTTPUploadFiles, now there are 2 new events: OnHTTPUploadBeforeSaveFile and OnHTTPUploadAfterSaveFile, allowing to know/modify the name of the file received.
[+] : Improved openSSL configuration, if openSSL_Options.LibPath = oslpCustomPath then will set the openSSL libraries location to the value of OpenSSL_Options.LibPathCustom (Thanks to Matteo for the suggestion).
[+] : Improved openSSL configuration, new property UnixSymLinks allows to disable the loading of SymLinks under Unix. Fixes the error "Clients should not load the unversioned libcrypto dylib as it does not have a stable ABI." under MacOS Monterey.
[+] : Improved openSSL error message "cannot load opensssl", now shows the path, methods not available and version. It's available only on Enterprise Edition.
[+] : Improved Socket.IO API, added support for latest API 4.
[+] : Added Support for Cryptorobotics Send Signal method.

[*] : Fixed Bug Indy Servers, in some cases half-disconnected http connections may make use of the full cpu. (Thanks to Moacir to let me know).
[*] : Fixed Bug when PerMessage_Deflate, handling a Z_BUF_ERROR message.
[*] : Fixed Bug when PerMessage_Deflate, if an empty string or memory stream was sent, an error was raised.
[*] : Fixed Bug when PerMessage_Deflate, if there was an internal error while inflating or deflating, the error message was not passed to the exception.
[*] : Fixed Bug when PerMessage_Deflate, when inflating a stream, if the buffer wasn't big enough, the stream wasn't fully compressed.
[*] : Fixed Bug TsgcWebSocketClient using plain TCP Protocol and TLS 1.3, the connection locks the thread during some seconds.
[*] : Fixed Bug when the property HTTPUploadFiles.RemoveBoundaries was enabled, the filename were not extracted on older Delphi versions.
[*] : Fixed Bug when the property HTTPUploadFiles.RemoveBoundaries was enabled, if the filename had spaces, the filename was not extracted completely.
[*] : Fixed Bug when compiling TsgcWebSocketClient_WinHTTP under CBuilder, Ambiguity error with Wininet unit (HINTERNET, INTERNET_PORT).
[*] : Fixed Bug MQTT Client read/write VarInteger values.
[*] : Fixed Bug MQTT Client when publishing a message with PublishProperties, always sent the property TopicAlias = 1.

[/] : The property TsgcWebSocketClient.Active now returns if the internal connection is Assigned or not. Before that, it called the Connected function of TCP Client.
