In version 6.0.0,

Address Verification

defines address requests and responses in JSON and defines the engine configuration in JSON.

Address Verification 5.x used XML to configure the engine and to define address requests and responses.

Address Verification

supports hot swapping of file sets. Hot swapping allows you to switch from one file set to another in seconds without deinitializing the process.

The main address processing functionality is encapsulated in one or more function servers. Each function server runs as a separate process, isolating the main process from any issues related to the address processing. If a function server fails, the event is reported back to the caller as an error and a new function server is started.

Address Verification 6.0.0 supports UTF-8 and UTF-16 encoding for input and output. Address Verification sets the encoding to UTF-8 or UTF-16 based on your use of 8-bit or 16-bit API functions.

When you use a function to submit or return a string value with UTF-16 characters, append W to the function name. For example, submit IDVE_PutStringW(). For functions that do not pass a string value, such as IDVE_Delete() and IDVE_Deinitialize(), use the function without W.
