Effective May 1, 2017
Legacy CryptoAPI Codec
It will be disabled in all default build configurations.
However, it will still be possible to build binaries with it enabled.
Design-Time Components for Visual Studio
They will still be built and included in the release packages.
However, they will no longer be "officially supported".
The mailing lists may still be used to ask questions about them.
However, any tickets opened for them will be deleted.
Release packages for non-current releases will be archived.
Access to archived release packages will be granted on a case-by-case basis.

- Write warning message to the active trace listeners (for the Debug build configuration only) if a column type or type name cannot be mapped properly. See [4bbf851fa5].
- When tracing SQL statements to be prepared, bypass the internal length limit of the sqlite3_log function by using the SQLiteLog class directly instead. Also, detect null and/or empty strings and emit a special message in that case.
- For the setup, the Visual Studio task should only be initially checked if the GAC task is available and vice-versa.
- Improve compatibility with custom command processors by using __ECHO instead of _ECHO in batch tools.
- Add OpenAndReturn method to the SQLiteConnection class to open a connection and return it.

- When returning schema information that may be used by the .NET Framework to construct dynamic SQL, use a fake schema name (instead of null) so that the table names will be properly qualified with the catalog name (i.e. the attached database name). Partial fix for [343d392b51].
- Add SQLiteSourceId property to the SQLiteConnection class to return the SQLite source identifier.
- Add MemoryUsed and MemoryHighwater properties to the SQLiteConnection class to help determine the memory usage of SQLite.
