    * handle all well known types in text mode and change `else if` to `switch`
* fix: released new versions of 42.2.29, 42.3.10, 42.4.5, 42.5.6, 42.6.2 to deal with `NoSuchMethodError on ByteBuffer#position` when running on Java 8 

## [42.7.2] (2024-02-21 08:23:00 -0500)

### Security
* security: SQL Injection via line comment generation, it is possible in `SimpleQuery` mode to generate a line comment by having a placeholder for a numeric with a `-` 
such as `-?`. There must be second placeholder for a string immediately after. Setting the parameter to a -ve value creates a line comment. 
This has been fixed in this version fixes [CVE-2024-1597](https://www.cve.org/CVERecord?id=CVE-2024-1597). Reported by [Paul Gerste](https://github.com/paul-gerste-sonarsource). See the [security advisory](https://github.com/pgjdbc/pgjdbc/security/advisories/GHSA-24rp-q3w6-vc56) for more details. This has been fixed in versions 42.7.2, 42.6.1 42.5.5, 42.4.4, 42.3.9, 42.2.28.jre7. See the security advisory for work arounds.

## [42.6.0] (2023-03-17 15:34:34 -0400)

### Changed
* fix: use PhantomReferences instead of `Obejct.finalize()` to track Connection leaks [PR #2847](https://github.com/pgjdbc/pgjdbc/pull/2847) 

    The change replaces all uses of Object.finalize with PhantomReferences.
    The leaked resources (Connections) are tracked in a helper thread that is active as long as
    there are connections in use. By default, the thread keeps running for 30 seconds after all
    the connections are released. The timeout is set with pgjdbc.config.cleanup.thread.ttl system property.

## [42.5.4] (2023-02-15 10:21:04 -0500)

### Fixed
* fix: fix testGetSQLTypeQueryCache by searching for xid type. We used to search for box type but it is now cached. xid is not cached, this nuance is required for the test.  
* fix OidValueCorrectnessTest BOX_ARRAY OID, by adding BOX_ARRAY to the oidTypeName map [PR #2810]((https://github.com/pgjdbc/pgjdbc/pull/2810).
* fixes [Issue #2804](https://github.com/pgjdbc/pgjdbc/issues/2804).  
* fix: Make sure that github CI runs tests on all [PRs #2809]((https://github.com/pgjdbc/pgjdbc/pull/2809)).

## [42.5.1] (2022-11-23 10:14:59 -0500)
### Security
- security: StreamWrapper spills to disk if setText, or setBytea sends very large Strings or arrays to the server. createTempFile creates a file which can be read by other users on unix like systems (Not macos).
This has been fixed in this version fixes CVE-2022-41946 see the [security advisory](https://github.com/pgjdbc/pgjdbc/security/advisories/GHSA-562r-vg33-8x8h) for more details.

### Security
- fix: CVE-2022-31197 Fixes SQL generated in PgResultSet.refresh() to escape column identifiers so as to prevent SQL injection.
  - Previously, the column names for both key and data columns in the table were copied as-is into the generated
  SQL. This allowed a malicious table with column names that include statement terminator to be parsed and
  executed as multiple separate commands.
  - Also adds a new test class ResultSetRefreshTest to verify this change.

### Added

### Fixed

## [42.3.2] (2022-02-01 07:35:41 -0500)
### Security
- CVE-2022-21724 pgjdbc instantiates plugin instances based on class names provided via authenticationPluginClassName, 
sslhostnameverifier, socketFactory, sslfactory, sslpasswordcallback connection properties.
However, the driver did not verify if the class implements the expected interface before instantiating the class. This
would allow a malicious class to be instantiated that could execute arbitrary code from the JVM. Fixed in [commit](https://github.com/pgjdbc/pgjdbc/commit/f4d0ed69c0b3aae8531d83d6af4c57f22312c813)

### Added
- feat: Add authenticationPluginClassName option to provide passwords at runtime
Adds authenticationPluginClassName connection property that allows end users to specify a class
that will provide the connection passwords at runtime. Users implementing that interface must
ensure that each invocation of the method provides a new char[] array as the contents
will be filled with zeroes by the driver after use.Call sites within the driver have been updated to use the char[] directly wherever possible.
This includes direct usage in the GSS authentication code paths that internally were already converting the String password into a char[] for internal usage.
This allows configuring a connection with a password that must be generated on the fly or periodically changes. [PR #2369](https://github.com/pgjdbc/pgjdbc/pull/2369) original issue [Issue #2102](https://github.com/pgjdbc/pgjdbc/issues/2102)

- fix: add microsecond precision to getTimestamp() called on sql TIME(6) Currently, "when fetching a value of type TIME(6) through
resultSet.getTimestamp() only ms precision is retained, the microsecond fractional digits are lost." This change will retain the microsecond
precision when .getTimestamp() is called on TIME(6). [PR #2181](https://github.com/pgjdbc/pgjdbc/pull/2181) Closes [Issue #1537](https://github.com/pgjdbc/pgjdbc/issues/1537)

## [42.3.1] (2021-10-29)
### Changed
- improv: Arrays in Object[] [PR 2330](https://github.com/pgjdbc/pgjdbc/pull/2330) when an Object[] contains other arrays, treat as though it were a

### Fixed
- Fix startup regressions caused by [PR #1949](https://github.com/pgjdbc/pgjdbc/pull/1949). Instead of checking all types by OID, we can return types for well known types [PR #2257](https://github.com/pgjdbc/pgjdbc/pull/2257)
- Backport [PR #2148](https://github.com/pgjdbc/pgjdbc/pull/2148)

- Backpatch [PR #2242](https://github.com/pgjdbc/pgjdbc/pull/2242) PgDatabaseMetaData.getIndexInfo() cast operands to smallint  [PR#2253](https://github.com/pgjdbc/pgjdbc/pull/2253)
  It is possible to break method PgDatabaseMetaData.getIndexInfo() by adding certain custom operators. This PR fixes it.
- Backpatching [PR #2251](https://github.com/pgjdbc/pgjdbc/pull/2251) into 42.2 Clean up open connections to fix test failures on omni and appveyor

## [42.2.23] (2021-07-06)
### Changed
- Renewed the SSL keys for testing

### Fixed
- getColumnPrecision for Numeric when scale and precision not specified now returns 0 instead of 131089 fixes: Issue #2188
- Calling refreshRow on an updateable resultset made the row readOnly. Fixes Issue #2193
- results should be updateable if there is a unique index available PR#2199 Fixes Issue #2196
- Rework sql type gathering to use OID instead of typname.
  This does not have the issue of name shadowing / qual-names, and has the added benefit of fixing #1948.


## [42.2.22] (2021-06-16)
### Fixed
- Regression caused by https://github.com/pgjdbc/pgjdbc/commit/4fa2d5bc1ed8c0086a3a197fc1c28f7173d53cac. Unfortunately
  due to the blocking nature of the driver and issues with seeing if there is a byte available on a blocking stream when it is encrypted
  this introduces unacceptable delays in returning from peek(). At this time there is no simple solution to this.


## [42.2.21] (2021-06-10)
### Changed
- Update docs to reflect deprecated DataSource API setServerName backpatch [PR#2057](https://github.com/pgjdbc/pgjdbc/pull/2057) [PR #2105](https://github.com/pgjdbc/pgjdbc/pull/2105)

### Fixed
- make sure the table has defined primary keys when using updateable resultset backpatch [PR#2101](https://github.com/pgjdbc/pgjdbc/pull/2101) fixes [Issue 1975](https://github.com/pgjdbc/pgjdbc/issues/1975) [PR #2106](https://github.com/pgjdbc/pgjdbc/pull/2106)

- Fix database metadata getFunctions() and getProcedures() to ignore search_path when no schema pattern is specified. backpatch [PR #2174](https://github.com/pgjdbc/pgjdbc/pull/2174)
  fixes [Issue 2173](https://github.com/pgjdbc/pgjdbc/issues/2173)


## [42.2.20] (2021-04-19)
### Fixed
- Partitioned indexes were not found fixes [#2078](https://github.com/pgjdbc/pgjdbc/issues/2078) PR [#2087](https://github.com/pgjdbc/pgjdbc/pull/2087)
- isValid() timeout should not be blocked [#1943](https://github.com/pgjdbc/pgjdbc/pull/1943) Cherry-picked [#2076](https://github.com/pgjdbc/pgjdbc/pull/2076)
  The usage of `setQueryTimeout();` with the same value as the `setNetworkTimeout();` is blocking the current transaction timeout.
  The timeouts are blocking each other with this approach.
- DatabaseMetaData.getTables returns columns in UPPER case as per the spec [PR #2092](https://github.com/pgjdbc/pgjdbc/pull/2092) fixes [Issue #830](https://github.com/pgjdbc/pgjdbc/issues/830)


## [42.2.19] (2021-02-18)
**Notable Changes**
- Now the driver uses SASLprep normalization for SCRAM authentication fixing some issues with spaces in passwords.
- If closeOnCompletion is called on an existing statement and the statement is executed a second time it will fail.

### Changed
- Perf: avoid duplicate PGStream#changeSocket calls
- Fix: Actually close unclosed results. Previously was not closing the first unclosed result fixes #1903 (#1905).
There is a small behaviour change here as a result. If closeOnCompletion is called on an existing statement and the statement
is executed a second time it will fail.

### Added
- Verify code via forbidden-apis (jdk-internal and jdk-non-portable signatures) [PR #2012](https://github.com/pgjdbc/pgjdbc/pull/2012)

### Fixed
- Fix Binary transfer for numeric fixes #1935
- Fix Allow specifying binaryTransferEnable even for those types that are not enabled by default
- Fix: properly set cancel socket timeout (#2044)
- Fix "Required class information missing" when old org.jboss:jandex parses pgjdbc classes [issue 2008][https://github.com/pgjdbc/pgjdbc/issues/2008]

- Fix Connection.isValid() to not wait longer than existing network timeout [PR #2040](https://github.com/pgjdbc/pgjdbc/pull/2040)
- Fix Passwords with spaces (ASCII and non-ASCII) now work with SCRAM authentication (driver now uses SASLprep normalization) [PR #2052](https://github.com/pgjdbc/pgjdbc/pull/2052)
- Fix DatabaseMetaData.getTablePrivileges() to include views, materialized views, and foreign tables [PR #2049](https://github.com/pgjdbc/pgjdbc/pull/2049)
- Fix Resolve ParseError in PGtokenizer fixes #2050
- Fix return metadata privileges for views and foreign tables


## [42.2.18] (2020-10-15)
### Fixed
- Unfortunately changing the default of gssEncMode to ALLOW was not enough. The GSSEncMode Enum was not changed as well
fixed in #1920


## [42.2.17] (2020-10-09)
### 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](https://github.com/pgjdbc/pgjdbc/pull/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] (https://github.com/pgjdbc/pgjdbc/pull/1873).
- The driver returns enum and jsonb arrays elements as String objects (like in 42.2.14 and earlier versions) [PR 1879](https://github.com/pgjdbc/pgjdbc/pull/1879).
- PgTokenizer was ignoring last empty token [PR #1882](https://github.com/pgjdbc/pgjdbc/pull/1882)
- Remove osgi from karaf fixes Issue #1891 [PR #1902](https://github.com/pgjdbc/pgjdbc/pull/1902)
- Handle nulls when the following classes are used: PGbox, PGcircle, PGline, PGlseg, PGpath, PGpoint, PGpolygon, and PGmoney.

## [42.2.16] (2020-08-20)
### 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](https://github.com/pgjdbc/pgjdbc/issues/1860) in [PR 1863](https://github.com/pgjdbc/pgjdbc/pull/1863).

## [42.2.15] (2020-08-14)
### Known issues
- The driver returns enum and jsonb arrays elements are returned as PGobject instances (fixed in 42.2.17)

### Changed
- Rename source distribution archive to `postgresql-$version-jdbc-src.tar.gz`, and add top-level archive folder [ba017507](https://github.com/pgjdbc/pgjdbc/commit/ba0175072ee9c751c1496d2fe170f4af7256f1a5)
- Add the ability to connect with a GSSAPI encrypted connection. As of PostgreSQL version 12 GSSAPI encrypted connections
are possible. Now the driver will attempt to connect to the server with a GSSAPI encrypted connection. If that fails then
attempt an SSL connection, finally falling back to a plain text connection. All of this is controlled using both the gssEncMode
and sslMode parameters which, in concert with pg_hba.conf, determine if a particular mode is allowed and or required. [PR 1821](https://github.com/pgjdbc/pgjdbc/pull/1821) [ad921b9e](https://github.com/pgjdbc/pgjdbc/commit/ad921b9e3563b28b9a03b1e2dfaad0e34efc02f1)
- Source release archive shades dependencies (scram) by default. It affects only postgresql-version-src.tar.gz release artifact [f0301eb9](https://github.com/pgjdbc/pgjdbc/commit/f0301eb901f880059b00b0fb0a3ee93ef7d749a8)
- Refactor decoding arrays [PR 1194](https://github.com/pgjdbc/pgjdbc/pull/1194)

### Added
- Verify nullness with CheckerFramework [6e524ae5](https://github.com/pgjdbc/pgjdbc/commit/6e524ae51cee67b25426c09a7083465c820c0a0d)

### Fixed
- Avoid preparedStatement leak when using updateable ResultSet via insert/update/refreshRow [PR 1815](https://github.com/pgjdbc/pgjdbc/pull/1815) [9a0d2b18](https://github.com/pgjdbc/pgjdbc/commit/9a0d2b18a81c7ec5974d4caf2ff2d218312da25f)
- Change order of checks for oid vs primary keys. OID's have been deprecated. [PR 1613](https://github.com/pgjdbc/pgjdbc/pull/1613)
- Close certificate file stream. [PR 1837](https://github.com/pgjdbc/pgjdbc/pull/1837)
- Make sure socketTimeout is enforced [PR 1831](https://github.com/pgjdbc/pgjdbc/pull/1831)
- Assume PKCS-8 SSL key format by default [PR 1819](https://github.com/pgjdbc/pgjdbc/pull/1819)
- Preserve unquoted unicode whitespace in array literals [PR 1266](https://github.com/pgjdbc/pgjdbc/pull/1266)

## [42.2.14] (2020-06-10)
### Changed
- Reverted com.github.waffle:waffle-jna, org.osgi:org.osgi.core, org.osgi:org.osgi.enterprise dependencies to optional=true in Maven [PR 1797](https://github.com/pgjdbc/pgjdbc/pull/1797).

## [42.2.13] (2020-06-04)

**Notable Changes**

- Security: The primary reason to release this version and to continue the 42.2.x branch is for CVE-2020-13692.
Reported by David Dworken, this is an XXE and more information can be found [here](https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html).
Sehrope Sarkuni reworked the XML parsing to provide a solution in commit [14b62aca4](https://github.com/pgjdbc/pgjdbc/commit/14b62aca4764d496813f55a43d050b017e01eb65).

## [42.2.12] (2020-03-31)

**Notable changes**

We have released 42.2.12 to correct regressions in this version: Specifically
- [PR 1729](https://github.com/pgjdbc/pgjdbc/pull/1729) was reverted as this is a breaking change
- [PR 1719](https://github.com/pgjdbc/pgjdbc/pull/1719) has been reverted as it introduced errors in the PgType Cache

We recommend that version 42.2.11 not be used.
### Changed

**Notable changes**
As mentioned above this version is broken and should not be used.
### Changed
 - Reverted [PR 1641](https://github.com/pgjdbc/pgjdbc/pull/1252). The driver will now wait for EOF when sending cancel signals.

### Added
 - docker-compose image for creating test databases (see `docker` folder)

## [42.2.10] (2020-01-30)
### Changed
 - (!) Regression: remove receiving EOF from backend after cancel [PR 1641](https://github.com/pgjdbc/pgjdbc/pull/1252). The regression is that the subsequent query might receive the cancel signal.

### Added
 - Add maxResultBuffer property [PR 1657](https://github.com/pgjdbc/pgjdbc/pull/1657)
 - add caller push of binary data (rebase of #953) [PR 1659](https://github.com/pgjdbc/pgjdbc/pull/1659)

- Use server-prepared statements for batch inserts when prepareThreshold>0. Note: this enables batch to use server-prepared from the first *executeBatch()* execution (previously it waited for *prepareThreshold* *executeBatch()* calls) [abc3d9d7](https://github.com/pgjdbc/pgjdbc/commit/abc3d9d7f34a001322fbbe53f25d5e77a33a667f)

- Ensure executeBatch() can be used with pgbouncer. Previously pgjdbc could use server-prepared statements for batch execution even with prepareThreshold=0. [Issue 742](https://github.com/pgjdbc/pgjdbc/issues/742)
- Error position is displayed when SQL has unterminated literals, comments, etc. [Issue 688](https://github.com/pgjdbc/pgjdbc/issues/688)
- Strict handling of accepted values in getBoolean and setObject(BOOLEAN), now it follows PostgreSQL accepted values, only 1 and 0 for numeric types are accepted (previously !=0 was true). [PR 732](https://github.com/pgjdbc/pgjdbc/pull/732)
- Return correct versions and name of the driver. [PR 668](https://github.com/pgjdbc/pgjdbc/pull/668)

### Removed

### Regressions
- Data truncated in setCharacterStream. Fixed in 42.1.0
- No suitable driver found for jdbc:postgresql when using a DataSource implementation. Fixed in 42.1.0
