Version 2.1.4 - 2018-08-28

General

• Drop support for versions of FreeTDS older than 0.91.

• Add Python 3.7 support

• Drop Python 3.3 support

Features

• Support for new in SQL Server 2008 DATE, TIME and DATETIME2 data
  types (GH-156). The following conditions need to be additionally met so
  values of these column types can be returned from the database as their
  native corresponding Python data types instead of as strings:

  • Underlying FreeTDS must be 0.95 or newer.
  • TDS protocol version in use must be 7.3 or newer.

  Thanks Ed Avis for the implementation. (GH-331)

Bug fixes

• Fix tds_version _mssql connection property value for TDS version.
  7.1 is actually 7.1 and not 8.0.

2.1.4 Release Candidate 1

• Windows official binaries: Rollback changes to Windows binaries we had implemented in pymssql 2.1.2; go back to using:
  • A statically linked version of FreeTDS (v0.95.95)
  • No SSL support
• Update bundled Linux static version of FreeTDS to v0.95.95.
• We now publish Linux PEP 513 manylinux wheels on PyPI.
• Add support for reporting TDS version 7.3 is in use via the tds_version property of a _mssql-level connection.

Attention Windows users: You need to download and install additional files. pymssql version 2.1.2 includes a change in the official Windows binaries: FreeTDS isn't statically linked as it happened up to release 2.1.1, as that FreeTDS copy lacked SSL support.

Please see http://pymssql.org/en/v2.1.2/freetds.html#windows for futher details.

We are trying to find a balance between security and convenience and will be evaluating the situation for future releases. Your feedback is greatly welcome.

Supported Python versions: Add 3.5, drop 2.6. Update bundled Linux FreeTDS static libs to 0.95. Add ability to set TDS protocol version from pymssql when connecting. Add Dockerfile and a Docker image. Fix a couple of very common causes of segmentation faults in presence of network partitions. Fix build fatal error when using Cython >= 0.22, and more...
