Millistream Database Application (MDA) version 0.9.52 released

The Millistream MDA project team is pleased to announce the release of version 0.9.52 of our open source application for updating SQL servers with data from the Millistream Data Feed.

  • Added support for SslMode in the MySQL/MariaDB connection string to disable SSL mode.
  • Added support for Diff4Y, DIff6Y, Diff7Y, DIff8Y and Diff9Y for both Price and Yield in the Performance table.
  • Added support for the new lastmodified column for various tables (sent in the feed as the Unix epoch but MDA 0.9.52 will convert to a proper datetime column).
  • Allow values in mda.config to be replaced by environment variables if they start with a $ character.
  • More robust handling of SQL errors when handling Corporate Actions messages with adjustment factors set.

As previously announced, as of v0.9.33 the database schema is developed independently of the MDA and the latest schema including upgrade scripts is available on our http server under the documents section  (MDA_schemas_[version].zip). As of this writing the latest database schema is v126 and is available from

Do note however that the latest schemas are only needed if you need the new columns/tables, they are not mandatory to operate the MDA!

We consider MDA 0.9.52 to be the best version of MDA available and we recommend that users of older versions upgrade as soon as possible.

MDA 0.9.52 is available for download from the following locations:

  • Debian/Ubuntu: “apt update && apt upgrade
