2022-08-30 - Version 2.8.2

Improvements:

• PLIN Status Display - Version 2.1.2: Improved calculating the client message rate by considering a possible client reset to avoid the display of negative message rates
• General code enhancements

Bug fixes:

• The LIN_GetFrameEntry function failed to return the error code errIllegalFrameID when the ID was out of range
• The LIN_GetVersion function returned a wrong version text. The revision and build parts were mixed up

• The error codes relating to the schedule table functions have been revised

Bug fixes:

• The LIN_RegisterClient function did not recognize the maximum number of clients and always returned a handle 1 if 255 clients were already created. In this case the function now returns errOutOfResource

Improvements:

• Added new function LIN_XmtDynamicWakeUp, to set a dynamic delay for wake-up message sending
