Notable changes

Fixed

• Unfortunately changing the default of gssEncMode to ALLOW was not enough. The GSSEncMode Enum was not changed as well fixed in #1920

Notable changes

Changed

• Change default of gssEncMode to ALLOW. PostgreSQL can deal with PREFER but there are cloud providers that did not implement the protocol properly. Libpq gets around this by checking for a GSS credential cache before attempting the connection. This is possible in JDK 8 and up, but not JDK6, or JDK7 fixes Issue #1868 PR #1913

Added

• Add smallserial metadata [PR #899(https://github.com/pgjdbc/pgjdbc/pull/899)

Fixed

• Avoid NullPointerException when receiving PGbox, PGcircle, PGline, PGlseg, PGpath, PGpoint, PGpolygon, and PGmoney PR 1873..
• The driver returns enum and jsonb arrays elements as String objects (like in 42.2.14 and earlier versions) PR 1879.
• PgTokenizer was ignoring last empty token PR #1882
• Remove osgi from karaf fixes Issue #1891 PR #1902

Notable changes

Known issues

• The driver returns enum and jsonb arrays elements are returned as PGobject instances (fixed in 42.2.17)

Fixed

• Arrays sent in binary format are now sent as 1 based. This was a regression for multi-dimensional arrays as well as text/varchar, oid and bytea arrays. Since 42.2.0 single dimensional arrays were stored 0 based. They are now sent 1 based which is the SQL standard, and the default for Postgres when sent as strings such as '{1,2,3}'. Fixes issue 1860 in PR 1863.
