Salesforce.com using the REST APIs
* module SqlUtil
-has support for native default values in tables
(issue 1428)
-has support for Oracle named types (eg. spatial types) for

Bug Fixes since Qore 0.8.12.4:
* module fixes:
-FixedLengthUtil: fixes and improvements to errors and
exceptions (issue 1828)
-HttpServerUtil: eliminated excess logging of all HTTP
chunks sent and received (issue 1832)

table column (issue 1886)
-SqlUtil: fixed a bug in the offset query hash argument
in SQL operation methods (issue 1880), fixed a bug
that prohibited only columns from the main query to be
selected when joins are used (issue 1909)
-TableMapper: fixed a bug in flush messages in the
InboundTableMapper class (issue 1849)
* fixed a bug that could cause spurious parse-time exceptions
to be thrown when matching call variants with multiple
return types for the same callable object (issue 1928)
* fixed the process return code in the output reference in
backquote() on Unix/Linux platforms (issue 1884)

back to the DatasourcePool in case of an SQLSTATEMENT-ERROR
exception (issue 1836)

objects based on a DatasourcePool are closed automatically
whenever the datasource is returned to the pool (issue 1250)

with a mix of lists and single values such as used by bulk
DML binds; now the single values will appear as the current
value for all list elements as per the original design
instead of throwing a runtime exception (issue 1738)

that could cause invalid data to be output or crashes on
32-bit platforms (issue 1640)
