Release Notes for JMRI 4.17.2 release

Date: mmm dd, 2019

From: (pumpkin)

Subject: Test Release 4.17.2 of JMRI/DecoderPro is available for download.

This is a draft release note only; the download links do not yet work

Notes:

This is a test release. Please post a note if you encounter any new or old bugs! And please back up your JMRI files before installing this, in case you want to go back to an earlier version.

This is the next in a series of test releases. We expect this series to end in the next JMRI production release late in 2019. (See the tentative release schedule)

Some of the changes involved are quite extensive. They may require a certain amount of experience before they are working well. Therefore, this test release should be considered experimental.

JMRI is now only available under the GNU General Public License. For more information, please see our copyright and licensing page.

Update From Older JMRI Versions

If you are currently using JMRI 4.11.9 or earlier, we strongly recommend that you update to JMRI 4.12 and make sure that's running OK before updating to this test release. Once you have JMRI 4.12 running OK, store your configuration and panel files and use those from then on. There have been a number of changes in serial port support, panel file format and configuration options since those earlier releases, and moving to the stable JMRI 4.12 release is a good way to work through any possible problems.

If you are currently using JMRI 4.7.3 or earlier on Linux or macOS (Windows doesn't need this), you must update to JMRI 4.12 and carrying out the migration process described in the JMRI 4.12 release note before updating to this release.
