The Chain Text feature, including the TextOffset property and Reset method, have been removed from the WGrammar API.
A problem where an error code would be returned if the path to the parts-of-speech database passed to the OpenSession method was an empty string has been fixed.
WGrammar has been completely redesigned and rewritten. Patterns to be matched are now expressed in a powerful pattern language that allows objects representing parts of English sentences to be defined once and referenced where needed. This greatly expands WGrammar's ability to detect problems in a large variety of sentence types. WGrammar's grammar-error database has also been completely rewritten to take advantage of the new search capabilities.
Sequences (strings of word patterns) are now grouped into targets. A target is a collection of one or more sequences that match text for some purpose (e.g., to detect a grammar error).
WGrammar now measures the ambiguity of matched text and returns a confidence score. The confidence score will help users in deciding if a problem report is a false positive.
WGrammar now supports trace files, which are diagnostic files that are helpful in debugging pattern problems.
WGrammar's API has been changed significantly.
The WGrammar Windows SDK now includes a COM object, which is a COM wrapper around the WGrammar DLL. An ASP (Active Server Pages) and VB.NET desktop example are also included.
The return value from most WGrammar functions (except WGrammar_OpenPatternFile, WGrammar_OpenIgnoreList, and WGrammar_OpenSession) is a signed, 32-bit value. Previously, most return types were signed 16-bit values.
WGrammar_AddPattern has been removed.
WGrammar_CompressPatternFile has been replaced by WGrammar_SavePatternFile. WGrammar_SavePatternFile saves all open pattern files to a single compiled pattern file.
WGrammar_IgnoreProblem has been replaced by WGrammar_IgnoreAll. WGrammar now supports multiple ignore lists that can be opened and closed via WGrammar_OpenIgnoreList and WGrammar_CloseIgnoreList. A new function, WGrammar_RemoveIgnoreAll, has been added.
WGrammar_LoadPatternFile has been replaced by WGrammar_OpenPatternFile.
WGrammar_OpenSession no longer takes as parameters the names of the parts-of-speech database file and map file. Instead, the path to the directory containing these files is passed instead.
WGrammar's license key is no longer provided as a hexadecimal constant. It is now provided as a signed, decimal constant, meaning no conversion is necessary when passing it to WGrammar_OpenSession.
WGrammar_GetProblemDescription and WGrammar_GetProblemReplacement have been removed. Instead, WGrammar_Run returns the description and replacement strings directly when a target is matched.
WGrammar_ResetIgnoreList has been replaced by WGrammar_ClearIgnoreList.
WGrammar_Run no longer returns a problem index, which was formerly used to access the description and replacement strings. Instead, the description and replacement strings are returned directly by the WGrammar_Run function. The problem id (an integer) has been replaced by the target id (a string). WGrammar_Run also returns a confidence score that indicates the degree of ambiguity of the matched text.
WGrammar_GetPatternFileInfo has been added. This function returns information about a pattern file.
WGrammar_GetTraceFile and WGrammar_SetTraceFile have been added. Trace files record information about target matches, and are useful in diagnosing WGrammar Pattern Language problems.
