+
−- Extended FileTransferHandler utility class by adding support for reading from
+
−  and writing to gzip compressed files when using file name extension .gz
+
−  Also improve error handling by testing on empty file name and provide more
+
−  information when invalid file name is given or other compression formats are
+
−  requested. As the FileTransferHandler utility class is used by JdbcClient
+
−  application, it will now also support this functionality.

+
−- Extended the MonetDB JDBC driver with support for the ON CLIENT clause of
+
−  the COPY statements. To make use of this functionality you must first
+
−  register handlers for upload and download of data.
+
−  The MonetConnection class has been extended with 2 methods:
+
−    public void setUploadHandler(UploadHandler uploadHandler)
+
−    public void setDownloadHandler(DownloadHandler downloadHandler)
+
−  The MonetDB JDBC driver API has been extended with interfaces:
+
−    public interface org.monetdb.jdbc.MonetConnection.UploadHandler
+
−    public interface org.monetdb.jdbc.MonetConnection.DownloadHandler
+
−  See onclient.txt for more information on how to use these from Java.
+
−  We also provide a utility class:
+
−    public class org.monetdb.util.FileTransferHandler
+
−  which provides an example implementation of the MonetConnection.UploadHandler
+
−  and MonetConnection.DownloadHandler interfaces useable for reading files
+
−  from or writing files to a local file system.

+
−- The JdbcClient application has been extended to support the new
+
−    COPY ... ON CLIENT functionality.
+
−  However for security reasons you must provide an explicit new startup argument
+
−    --csvdir "/absolute/path/to/csvdatafiles"
+
−  or on MS Windows
+
−    --csvdir "C:\\path\\to\\csvdatafiles"
+
−  in order to activate the JdbcClient application to down/up load data to/from
+
−  the local file system.
+

+
−* Mon Jun 14 2021 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
+
−- Compiled and released new jar files: monetdb-jdbc-3.1.jre8.jar,
+
−  monetdb-mcl-1.20.jre8.jar and jdbcclient.jre8.jar
+
−
+
−* Thu Apr 29 2021 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
+
−- Improved performance of ResultSetMetaData methods getPrecision(),
+
−  getScale(), isNullable() and isAutoIncrement(). The data is fetched
+
−  from the server by sending a query. This used to be one query for
+
−  each column of the ResultSet. Now these metadata queries are combined
+
−  into one query fetching this meta data for up to 50 columns in one query.
+
−  This reduces the number of queries sent to the server significantly.
+
−  This is noticable for instance when using generic JDBC query tools
+
−  such as SQuirreL, DBeaver, which now respond much faster.
+

+
−* Wed Mar  3 2021 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
+
−- Implemented PreparedStatement.toString() as requested by
+
−  https://github.com/MonetDB/monetdb-java/issues/8
+
−
+
−* Wed Mar  3 2021 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
+
−- Implemented fix for released monetdb-jdbc-3.0.jre8.jar and
+
−  monetdb-mcl-1.19.jre8.jar when it is was run using java build 1.8.0_###.
+
−  It would throw:
+
−  java.lang.NoSuchMethodError: java.nio.CharBuffer.mark()Ljava/nio/CharBuffer;
+
−  at org.monetdb.mcl.parser.StartOfHeaderParser.getNextAsString(Unknown Source)
+
−  at org.monetdb.jdbc.MonetConnection$ResponseList.executeQuery(Unknown Source)
+
−  at org.monetdb.jdbc.MonetConnection$ResponseList.processQuery(Unknown Source)
+
−  at org.monetdb.jdbc.MonetStatement.internalExecute(Unknown Source)
+
−  at org.monetdb.jdbc.MonetStatement.execute(Unknown Source)
+
−  The problem is caused by a change in java.nio.CharBuffer API (return
+
−  types of methods mark() and reset() have changed from Buffer to
+
−  CharBuffer) from Java 8 to Java 9+.
