* Thu Oct 2 2025 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
6+
- Compiled and released new jar files: monetdb-jdbc-12.1.jre8.jar and
7+
jdbcclient.jre8.jar
8+
9+
* Thu Sep 18 2025 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
10+
- Added support for new MonetDB data types: inet4 and inet6.
11+
12+
* Tue Sep 9 2025 Joeri van Ruth <joeri.van.ruth@monetdbsolutions.com>
13+
- Fixed the 'debug' and 'logfile' properties. The log file was opened
14+
but immediately closed again.
15+
- Made the log file name choosing algorithm more robust against race
16+
conditions: instead of checking whether the intended file already exists
17+
and opening it when it doesn't, open it in 'create' mode and handle
18+
the error that gets thrown when it already exists.
19+
- conn.getMetaData().supportsTransactionIsolationLevel() now always
20+
returns 'true' exept for level TRANSACTION_NONE. It used to return 'true'
21+
only for TRANSACTION_SERIALIZABLE, but serializable actually implies
22+
the other levels. Matches the behavior of PostgreSQL.
23+
24+
* Mon Sep 1 2025 Joeri van Ruth <joeri.van.ruth@monetdbsolutions.com>
25+
- Automatic compression and decompression in FileTransferHandler can now
26+
be disabled by passing 'false' as the third constructor parameter.
27+
28+
* Thu Jul 3 2025 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
29+
- Corrected output of columns SEARCHABLE and AUTO_INCREMENT of method
30+
DatabaseMetaData.getTypeInfo(). Most types are searchable with LIKE
31+
pattern matching. AUTO_INCREMENT is no longer true for base integer types.
32+
33+
* Fri Apr 4 2025 Joeri van Ruth <joeri.van.ruth@monetdbsolutions.com>
34+
- Improve error message when server closes the connection immediately after
35+
accepting it.
36+
37+
* Wed Mar 31 2025 Joeri van Ruth <joeri.van.ruth@monetdbsolutions.com>
38+
- Fixed more result set leaks.
39+
40+
* Wed Feb 26 2025 Joeri van Ruth <joeri.van.ruth@monetdbsolutions.com>
41+
- Properties 'clientkey' and 'clientcert' are no longer included in the
42+
result of Driver#getPropertyInfo() because though the driver recognizes
43+
them, it does not support them.
44+
- Fixed a number of result set leak when Statement#setMaxRows was called.
45+
46+
* Thu Feb 13 2025 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
47+
- Corrected the returned integer values of Statement methods
48+
getUpdateCount() and getLargeUpdateCount(). They returned -2 for
49+
DDL statements, which was not in compliance with the JDBC API
50+
documentation. Now they no longer return numbers smaller than -1.
51+
- Corrected the returned integer values of Statement methods
52+
executeUpdate(...) and executeLargeUpdate(...) and PreparedStatement
53+
methods executeUpdate() and executeLargeUpdate(). They returned -2 for
54+
DDL statements, which was not in compliance with the JDBC API
55+
documentation. Now they no longer return negative numbers.
56+
57+
* Wed Feb 12 2025 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
58+
- Fix a bug in DatabaseMetaData.getTables() where a provided string in the
59+
array of table types argument would contain a single quote or back slash.
60+
It was not escaped properly, resulting in an SQL syntax error.
61+
- Fix missing escaping of single back slashes in string data provided to
62+
PreparedStatement methods setString(), setClob(), setObject() and setURL().
63+
64+
* Thu Jan 16 2025 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
65+
- The release version number has been bumped to 12.0 to avoid confusion
66+
with historic 11.x versions.
67+
- Compiled and released new jar files: monetdb-jdbc-12.0.jre8.jar and
68+
jdbcclient.jre8.jar
69+
70+
* Wed Jan 8 2025 Joeri van Ruth <joeri.van.ruth@monetdbsolutions.com>
71+
- The JDBC jar now includes JdbcClient. For backward compatibility the jar
72+
is still also available as jdbcclient.jreX.jar.
73+
74+
* Thu Nov 7 2024 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
75+
- In JdbcClient when running the \vsci or \vdbi or \vsi commands, we now
76+
suppress "42000 SELECT: insufficient privileges for ..." and
77+
"42000 SELECT: access denied for ..." error messages when the connected user
78+
does not have 'monetdb' or 'sysadmin' privileges, needed for some validations.
79+
80+
* Wed Jun 19 2024 Joeri van Ruth <joeri.van.ruth@monetdbsolutions.com>
81+
- Implemented Connection#set/getClientInfo, and send sensible default info
82+
at connect time. This can be controlled with the properties 'client_info=on/off',
83+
'client_application=ApplicationName' and 'client_remark=Other Useful Info'.
84+
Note setting client info requires MonetDB server 11.51 (Aug2024) or higher.
85+
86+
* Thu Apr 4 2024 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
87+
- Corrected ResultSetMetaData methods getColumnTypeName(), getPrecision(),
88+
getColumnDisplaySize() and ParameterMetaData methods getParameterTypeName()
89+
and getPrecision() for the interval data types. They now return
90+
more precise information for the 13 possible interval data types.
91+
92+
* Thu Mar 7 2024 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
93+
- Improved DatabaseMetaData.getTypeInfo(). It now also returns the serial
94+
and bigserial data types and all 13 possible interval data types.
95+
96+
* Fri Jan 5 2024 Joeri van Ruth <joeri.van.ruth@monetdbsolutions.com>
97+
- Network connections can now be encrypted with TLS by using jdbc:monetdbs://..
98+
instead of jdbc:monetdb://. The server is authenticated using the JVM's root
99+
certificate pool unless cert= or certhash= properties are given.
100+
- The syntax of the JDBC URL's has been updated to match the monetdb:// and
101+
monetdbs:// URL syntax introduced in MonetDB 11.51 (Aug2024), see
102+
https://www.monetdb.org/documentation/user-guide/client-interfaces/monetdb-urls/.
103+
This adds a number of properties that can be set in the URL but is otherwise
104+
backward compatible except that percent sign are now used to escape other characters.
105+
For example, the password '100%milk&cookies' can be passed as
106+
password=100%25milk%26cookies.
107+
108+
* Thu Dec 28 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
109+
- In ResultSet.getObject(column, Class<T> type) and
110+
ResultSet.getObject(column, Map<String,Class<?>>) methods added support
111+
to return objects for classes: java.time.LocalDate, java.time.LocalDateTime
112+
and java.time.LocalTime.
113+
114+
* Wed Dec 20 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
115+
- Enhanced DatabaseMetaData.getTables() method by adding support for SQL
116+
table type names: 'BASE TABLE', 'GLOBAL TEMPORARY' and 'LOCAL TEMPORARY'
117+
in parameter types[]. These are SQL synonyms of MonetDB table type names:
118+
'TABLE', 'GLOBAL TEMPORARY TABLE' and 'LOCAL TEMPORARY TABLE'.
119+
120+
* Thu Dec 14 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
121+
- In ResultSet.getObject() method added support for retrieving
122+
TIMESTAMP WITH TIME ZONE data as java.time.OffsetDateTime object
123+
and TIME WITH TIME ZONE as java.time.OffsetTime object.
124+
Also methods ResultSetMetaData.getColumnClassName() and
125+
ParameterMetaData.getParameterClassName() now return
126+
java.time.OffsetDateTime.class for columns of type TIMESTAMP WITH TIME ZONE
127+
and java.time.OffsetTime.class for columns of type TIME WITH TIME ZONE.
128+
129+
* Thu Oct 12 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
130+
- Improved DatabaseMetaData.getSystemFunctions(). It now also returns
131+
functions: current_sessionid, greatest, ifnull, least, sql_max, sql_min.
132+
Function ifnull will only be returned for servers Jun2023 (11.47 or higher).
133+
134+
* Wed Aug 9 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
135+
- Implemented ResultSet methods:
136+
<T> T getObject(int columnIndex, Class<T> type)
137+
<T> T getObject(String columnLabel, Class<T> type)
138+
They used to throw an SQLFeatureNotSupportedException.
139+
140+
* Thu Jul 6 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
141+
- Removed deprecated nl.cwi.monetdb.*.* classes and package.
142+
Those classes were marked deprecated on 12 Nov 2020 from
143+
release 3.0 (released on 17 Feb 2021) onwards. It includes:
144+
nl.cwi.monetdb.client.JdbcClient.class
145+
nl.cwi.monetdb.jdbc.MonetDriver.class
146+
nl.cwi.monetdb.jdbc.types.INET.class
147+
nl.cwi.monetdb.jdbc.types.URL.class
148+
nl.cwi.monetdb.mcl.net.MapiSocket.class
149+
These classes are now removed permanently.
150+
Use the org.monetdb.* equivalents instead.
151+
152+
* Thu Jul 6 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
153+
- Removed code to support old MonetDB servers Oct2014 or older. Those
154+
old servers did not yet have the system tables: sys.keywords and
155+
sys.table_types which are introduced in Jul2015 release. Those system
156+
tables are used by MonetDatabaseMetaData methods: getSQLKeywords(),
157+
getTableTypes() and getTables(). These 3 methods will now fail when
158+
used with those very old MonetDB servers.
159+
160+
* Wed Jul 5 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
161+
- Corrected implementation of Connection methods getClientInfo() and
162+
setClientInfo(). They used to get/set Connection properties instead of
163+
Client Info properties, which was incorrect.
164+
165+
* Thu Jun 22 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
166+
- Corrected DatabaseMetaData method getClientProperties().
167+
It used to return connection properties instead of client info properties.
168+
169+
* Thu May 4 2023 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
170+
- Corrected DatabaseMetaData method getStringFunctions() when connected
171+
to Jun2023 server. It now includes the string functions from the new
172+
txtsim module.
173+
5174
* Thu Jan 16 2025 Martin van Dinther <martin.van.dinther@monetdbsolutions.com>
6175
- The release version number has been bumped to 12.0 to avoid confusion
7176
with historic 11.x versions.
