Changes in version 10.0.0

Beginning with version 10.0.0, the name of the library is WFDB. All earlier versions were named DB. All library symbols have been similarly renamed, with WFDB and wfdb replacing DB and db everywhere, in names of library functions, constants, type and structure definitions, library source file names, and names of environment variables (e.g., the DB environment variable is now the WFDB environment variable).

Version 10.0.0 of the WFDB library is functionally identical with the final release (version 9.7.4) of the DB library, except for the name changes. It should be possible to recompile existing applications written for DB library version 9.x without modification, and to link them with WFDB library version 10.0.0. This is possible because two sets of #include files are provided with the WFDB library. The first set, accessible via #include <wfdb/...>, works with applications written as described in this guide. The alternate set, accessible via #include <ecg/...>, is compatible with DB 9.x applications as described in previous editions of this guide.
