Wildcat! Version 10.0 Summary:

Wildcat! Version 10.0 (Build 500.3) continues the v10 platform with a new SFTP server for secure file exchange, Fidonet/BinkP integration via Platinum Xpress, CHM help modernization, and server improvements. Key highlights include:

• NEW (500.3): Wildcat! SFTP Server - file transfer over SSH for trading partners who require it. It serves the same file groups, file areas and paths as the FTP server, and the wcBASIC hooks fall back to their FTP equivalents, so an existing ftpscanfile or ftplogon application runs unchanged.
• NEW (500.3): SFTP Server configuration added to wcConfig - per-computer SFTP port, access profiles, namespace and listing options, log options and IP tracking.
• NEW (500.3): Automatic file descriptions on upload from FILE_ID.DIZ or MP3 tags, shared by the FTP and SFTP servers.
• NEW (500.3): WcFreeMemory() added to the Wildcat! SDK - lets Python, C# and VB.NET clients release buffers allocated by wcsrv2.dll.
• NEW (500.2): Platinum Xpress BinkP/1.1 Fidonet mailer support - inbound and outbound file transfers over TCP/IP. See PX/WIN 500.2 Changes for the complete component-level detail.
• NEW (500.2): BINKP.UMP modem profile for BinkP node configuration.
• NEW (500.2): Nodelist IBN/INA flag support for BinkP hostname discovery.
• NEW (500.2): fidomsg.wcx outbound Fidonet netmail trigger via semaphore signal.
• NEW (500.2): wcWEB Fidonet nodelist autosuggest for the new message compose form - search by sysop name or FTN address, AKA zone auto-select, AreaFix/FileFix password autofill (html-suggest-nodes.wcx, html-get-fixpwd.wcx).
• NEW (500.2): defender-exclusions.cmd - optional Windows Defender process and path exclusion script for Wildcat! servers on Windows Server 2022/2025.
• FIX (500.2): wcHTTPS now rejects unauthenticated POST requests before writing to disk, eliminating Defender security alerts from bot-generated exploit payloads.
• CHG (500.2): Platinum Xpress help updated from *.hlp (WinHelp) to *.chm (HTML Help).
• Complete migration of source control from CVS to Git for sustainable version management.
• Reorganized source tree into backend, middleware, and frontend components for modular development.
• All images rebuilt from the updated environment with outputs validated against the final 8.0.454.16 release.
• Backend Wildcat! Server continues as 32-bit and 64-bit builds with modern Visual Studio toolchains.
• wcSSL updated to OpenSSL 3.4.0 across server and client modules.
• Updated build system ensures consistent Debug/Release, Win32/x64 outputs via global props configuration.
• Support for Wildcat! Modem/TAPI RS232 remains available for legacy installations.
• AUP upgrade process streamlined - Sysops should ensure wcRPC DLLs used by external apps are updated to match Build 500.2 to avoid version mismatches.
