Hi,
   a new version has been released.

Just a minor change since release candidate 3.

User visible (not in a particular order):
- Sybase server:
  - All strings are now converted as MSSQL;
  - Support kerberos login;
  - DB-Library: add DBSETNETWORKAUTH, DBSETMUTUALAUTH, DBSETDELEGATION and
    DBSETSERVERPRINCIPAL;
  - CT-Library: add CS_SEC_NETWORKAUTH, CS_SEC_NETWORKAUTH,
    CS_SEC_NETWORKAUTH and CS_SEC_NETWORKAUTH;
- Bulk copies:
  - DB-Library: fix trim of unicode fields;
  - (*) Apply character conversion for Sybase, like MSSQL;
  - (*) Ignore computed columns;
  - (*) Properly support multibyte strings in column names;
  - (*) DB-Library: stop correctly on BCPMAXERRS setting;
  - (*) DB-Library: do not try to convert skipped rows reading file allowing
    for instance to load CVS files;
- (*) CT-Library: added CS_DATABASE property to allows to connect correctly
  to Azure servers;
- (*) Improve support for MS XML columns for both DB-Library and CT-Library;
- (*) Fix some issues with MSSQL server redirection (used for instance in
  Azure);
- (*) Change SQL_DESC_OCTET_LENGTH value for wise character columns;
- Better support for SQL_VARIANT:
  - Better column checks;
  - (*) CT-Library: now supported, columns are returned as CS_CHAR_TYPE;
- Some updates to server part:
  - Set correctly initial state;

odbc_set_string_flag
  fixing some character encoding support;
- (*) Fix multiple queries, used by ODBC to optimize data load;
- (*) Improve emulated parameter queries, fixing minor issues and reducing
  memory usage;
- Support DBVERSION_UNKNOWN in dbsetlversion (will use automatic detection);

Implementation:
- User guide converted to XML;
- Always use little endian on network level, simpler and faster;
- Converted some files to markdown;
- Optimize bytes endianess conversion;
- Made character lookup faster making character conversion quicker;
- Optimize data padding in CT-Library;
- Fix some build dependencies causing some files to not be properly
  recompiled during development;
- Add "freeze" support allowing to pause sending in order to simplify
  lengths computations sending data.


Kind Regards,
