WiltonDB 3 LTS (version 12.16.1) is released for Windows and Linux.

WARNING: THIS UPDATE IS NOT COMPATIBLE WITH DB CLUSTERS FROM PREIVIOUS WILTONDB VERSIONS

This update includes breaking changes implemented to fix the #2987 problem. Because of this there is no update path from version 11.15.1 - new DB cluster must be created. On Windows this is done automatically - default installation directory is changed to C:\Program Files\WiltonDB Software\wiltondb_3_lts. On Linux the existing DB cluster needs to be removed before running wiltondb-setup.

Microsoft Visual C++ Redistributable update:

Before installing this update on Windows it is necessary to update Microsoft Visual C++ Redistributable package to version 14.40.33810.0 or later. Latest version of MSVC 2022 compiler has introduced incompatibility with older versions of Redistributable package (details: 1, 2), when running on older version of Redistributable package WiltonDB may randomly crash with the following message:

Faulting application name: postgres.exe, version: 15.0.4.24180, time stamp: 0x66803d50
Faulting module name: MSVCP140.dll, version: 14.36.32532.0, time stamp: 0x04a30cf0
Exception code: 0xc0000005
Fault offset: 0x0000000000012f58
Faulting application path: C:\Program Files\WiltonDB Software\wiltondb3.3\bin\postgres.exe
Faulting module path: C:\Windows\SYSTEM32\MSVCP140.dll

Bugfixes:

• OpenSSL library is updated to version 3.0.14 that includes one low-severity security fix
• a number of fixes backported from upstream Babelfish. To apply the changes related to string literals handling in COALESCE function to existing DB clusters, it is necessary to upgrade babelfishpg_common extension to version 3.3.3 by running the following SQL on Postgres connection (default port 5432):

ALTER EXTENSION "babelfishpg_common" UPDATE TO '3.3.3'

Notable changes:

• this update introduces support for jTDS JDBC driver. Note, useCursors jTDS option is not supported - cursors are supported when used directly through JDBC API (excluding cursor.last() call)
• DEFAULT keyword is supported as a parameter to T-SQL function and procedures.

2024-05-16

WiltonDB 3.3 update (version 8.13.1) is released for Windows and Linux.

Bugfixes:

• this release includes a fix to CVE-2024-4317 from upstream PostgreSQL 15.7. To apply the fix to existing DB clusters it is necessary to run <installdir>/share/fix-CVE-2024-4317.sql script on Postgres connection (default port 5432)
• #2540 fix is backported from upstream Babelfish. It fixes the problem when altering a table to add a column with DEFAULT NEWID() makes the values all the same value which is not the correct behaviour. To apply the fix to existing DB cluster it is necessary to run the following SQL on Postgres connection (default port 5432):

ALTER EXTENSION "babelfishpg_common" UPDATE TO '3.3.2'

Notable changes:

• support for ALTER AUTHORIZATION ON DATABASE::<dbname> TO <login-name> (#1954) is backported from upstream Babelfish. It allows to easily create login-owned databases, see details on Logins and users wiki page
• support for FOR JSON AUTO (#2243) is backported from upstream Babelfish
• default TDS debug logging, which was creating multiple log records for every connection, is disabled; this behaviour can be controlled by changing babelfishpg_tds.tds_debug_log_level system parameter from 0 (disabled) to 3 (max verbosity)
