Notes

• Users of DMDext v2.3.1 can simply download the appropriate packages below and extract zedmd.dll or zedmd64.dll into their VPinMAME folder. Don't forget to unblock the DLLs. The other DLLs in that packages are not needed!

• load UDP delay in single request handshake as well
• send USB handshake as chunks

• ensure that no command gets lost
• add CPU info to zdmd-client
• fixed minor API issues for the updater
• perform two attempts to clear the serial buffer before handshake
• log libserialport errors
• more logging
• perform additional restet for USB CDC
• expose IsS3()
• expose FormatLogMessage()
• expose GetPanelWidth() and GetPanelHeight()
• expose SetLogCallback()

• longer timeout for sending USB handshake
• removed additional reset on USB connect
• fixed info data via WiFi
• provide a lot of panel specific data for clients
• improved USB auto-discovery
• fixed panel i2s speed setting

• clear screen instead of reset with Wifi
• less strict handshake
• renamed zedmd_test and zedmd_test_s to zedmd-test and zedmd-test-portable
• added experimental zedmd-client and zedmd-client-portable to configure advanced ZeDMD settings

• Fixed ESP32 S3 USB CDC connect issues on Windows
• Added TCP support
• Quicker WiFi handshake

ZeDMD 5.1.0 or newer is required!
