      Release Notes: A bug that caused PBXT to corrupt the index file when the size exceeded 4 GB has been fixed. This release runs under Windows. This source tree must be placed in the MySQL source storage directory in order to compile. Further details of how to build are in the windows-readme.txt file. This release checks for repeat updates of a record in a statement. It avoids checking for duplicates if an index is not modified by an update. Records updated repeatedly by a transaction are now updated in place.
