All the downloads that are available for Orthanc, including official releases and precompiled plugins.

Remark: All the Windows binaries from this Web page (i.e. all the .exe and .dll files) are compiled for 32bit architecture. Consequently, the precompiled plugins (.dll) can only be used by a 32bit version of Orthanc. An installer for Windows 64bit, containing all the plugins, is available on this page courtesy of Osimis.

* Remove "ASSERT" in SQL for compatibility with older releases of PostgreSQL
* Implementation of new extensions: LookupResourceAndParent and GetAllMetadata

Release 2.2 (2018-07-16)

!! Important remark when upgrading from an older version of the plugin:

   The plugin will create a new index to improve search performance.
   This can take several minutes at the first Orthanc startup. Orthanc
   will not be available during this period. On a PostgreSQL database
   with 100,000 studies, we have observed that updating the index took
   around 10 minutes.

* Migration into the "orthanc-databases" repository
* Full refactoring to share code with MySQL
* Fix issue 41 (Additional range IdentifierConstraintType in Orthanc)
  !! This fix requires Orthanc version >= 1.4.0
* Fix issue 47 (Index improvements for PG plugin)
* Fix issue 76 (PG connection shall reconnect/retry in case it loses
  the connection to the server)

Release 2.1 (2018-04-20)

* Running transactions in "Serializable" isolation level to avoid

* Fix issue 62 (use correct type for lo_read() value)

* Fix issue 68 (PostgreSQL plugin needs extra flags to compile)
* Resort to Orthanc framework
* Support of Linux Standard Base, OpenBSD and FreeBSD
