Version Information

The major and minor version numbers of SciDB-Py track the major and minor version of SciDB they are compatible with. For example SciDB-Py 16.9.1, 16.9.2 or 16.9.10 are all compatible with SciDB 16.9.x.

During SciDB 16.9, Shim (HTTP service for SciDB) transitioned from query authentication to session authentication. SciDB-Py has been updated to be compatible with the new Shim. Below is the compatibility matrix between SciDB-Py and Shim:

SciDB-Py	Shim
16.9.1	query authentication (old Shim)
16.9.2	query authentication (old Shim)
16.9.10	session authentication (new Shim)

From 16.9.10 onwards only Shim with session authentication is supported.

Since SciDB-Py Release 16.9.1 (released in September 2017) the library has been rewritten entirely from scratch. 16.9.1 and newer versions are not compatible with the previous versions of the library. The documentation for the previous versions is available at SciDB-Py documentation (legacy). GitHub pull requests are still accepted for the previous versions, but the code is not actively maintained.
