ICS V8.62 has been released at:


ICS is a free internet component library for Delphi 7, 2006 to 2010, XE to XE8, 10 Seattle, 10.1 Berlin, 10.2 Tokyo and 10.3 Rio, and C++Builder 2006 to XE3, 10.2 Tokyo and 10.3 Rio. ICS supports VCL and FMX, Win32, Win64 and MacOS targets.

The distribution zip includes the latest OpenSSL 1.1.1c win32, with other versions of OpenSSL being available from the download page.

Major Changes in ICS V8.62 include:

1 - The HTTP client has new properties. There is a new THttpAuthType of httpAuthJWT which uses the AuthBearerToken property for Json Web Token authentication. A new ProxyURL property combines four proxy properties as a URL for simplicity, ie http://[user[:password]@]host:port. The new AlpnProtocols property is a request list sent when an SSL connection starts, once connected GetAlpnProtocol returns which protocol the server wants to uses.

2 - Various improvements for automatic X509 SSL certificate ordering to support final ACME RFC8555. AcmeV2 now supports POST-as-GET, GET alone being removed later in 2019. Added Proxy URL support, might be needed for servers behind NAT firewalls for public access. Added support tls-alpn-01 challenge for local web server on 443, but not working yet.

3 - SocketServer now uses a separate local web server for servers not using ports 80 or 443 such as FTP, SMTP, proxies, etc, When ordering X509 SSL certificate using ChallFileSrv challenge.

4 - TWsocket now raises a background exception for user exceptions in the OnDataAvailable event rather than silently ignoring them. If IcsLogger is being used, HandleBackGroundException now logs exceptions and their source to make them easier to find.

5 - In the TSslHttpRest component, TRestParams can add Json parameters as PContJson which means arrays and nested Json can be added. Added a new SslAllowSelfSign property to connect OK to sites with self signed SSL certificates which would normally fail validation.

6 - TSimpleWebSrv now supports SSL, with certificate bundle and host name, and supports the SSL ALPN extension for automatic X509 SSL certificate ordering.

7 - The new TIcsSms component adds support for SMS Works bureau at https://thesmsworks.co.uk/ to send SMS messages, cheaper than Kapow, and allows sender ID to be freely changed.

8 - Updated all .dproj files for all samples to add the ICS source folder to the search path of each project. 

9 - Added Time Zone support for date string conversions, to UTC time with a time zone, and back to local time using a time zone, primarily for SMTP email headers which otherwise show UTC time.
10 - TIcsIpStrmLog using TCP server now uses the root bundle correctly and reports the certificate chain and bindings. Ensure all listeners started for TCP Server, if more than one.
