+The [nightly](https://github.com/DSheirer/sdrtrunk/releases/tag/nightly) release contains current builds of the software 
+for all supported operating systems.  This version of the software may contain bugs and may not run correctly.  However,

+playlist(s) before you use the nightly builds.**  Note: the nightly release is updated each time code changes are 
+committed to the code base, so it's not really 'nightly' as much as it is 'current'.

-Auto-generating Java code from SDRPlay API using jextract.
-
-Note: the api headers in the 3.11 folder are equivalent to the 3.08 headers.  The only
-difference from the 3.07 headers is the addition of the boolean 'valid' flag to DeviceT structure.
-
-1. Download JDK19 compatible build of jextract JDK: https://jdk.java.net/jextract/
-2. If generating on windows platform, modify the sdrplay_api.h to remove the windows
-   pieces of the file.  Specifically:
-2a. Comment out these lines but leave the *HANDLE typedef:
-
-//#if defined(_M_X64) || defined(_M_IX86) || defined(_M_ARM64)
-//#include "windows.h"
-//#elif defined (__GNUC__)

-//#elif defined(STATIC_LIB) || defined(__GNUC__)
-//#define _SDRPLAY_DLL_QUALIFIER
-//#endif
-//#endif  // _SDRPLAY_DLL_QUALIFIER
-
-2b. Remove the '_SDRPLAY_DLL_QUALIFIER' from in front of the method declarations
-
-2c. Change the 3.11 version string to 3.08 either in the header file, or in the generated java class
-
-3. Open command prompt to the root source code where the generated files should be placed:
-..\SDRtrunk\sdrplay-api\src\main\java
-
-4. Generate the code:
-c:\Users\Denny\Downloads\jdk-19-ea2-panama\bin\jextract "C:\Users\Denny\git\sdrtrunk\sdrplay-api\api\v3_11\sdrplay_api.h" -l libsdrplay_api --source
-
-5. Do this for all versions of the API.
