Release Notes for JMRI 4.15.5 release
Date: mmm dd, 2019
Subject: Test Release 4.15.5 of JMRI/DecoderPro is available for download.
This is a draft release note only; the download links do not yet work
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 during early Summer 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.
Update From Older JMRI Versions
If you are currently using JMRI 4.9.6 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. 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.
Known problems with this release
New warnings for this release:
Older warningsSee the JMRI 4.14 release note for more warnings predating the 4.15 development series. These may be relevant to you if you're updating from an earlier version.
Since JMRI 4.15.3 The prefix that identifies a layout connection should be a single letter, like "N" or "L", or a letter and some digits, like "K2" or "D3". Some older systems used to have longer "legacy system prefixes" like "DX", "DCCPP", "DP", "MR", "MC", "PI", and "TM". Those legacy system prefixes will now cause JMRI to issues a warning at startup. In this release, JMRI will still work with those prefixes, but they will need to be migrated to the proper form soon; JMRI 4.17.1 and later will require that this have been fixed. Therefore, this warning can't be suppressed without migrating the prefix in the connection configuration (and any associated panel files and scripts). If you're getting this warning and therefore need to do that migration, migration page.
Since JMRI 4.11.4 There are issues with the Pi-SPROG One command station operation. A number of workarounds should be applied:
- Do not turn on the track power until the power supply to the Pi-SPROG ONE is turned on
- Do not enable extra debugging through default.lcf, nor open the system console window
- Do not open the SPROG console window
- Disable power conversion (CV 29) in all locos
- If connecting via VNC (or similar), setup the screen layout before turning on the track power
Download links:During development leading to the actual release, you can find test download files on the continuous integration build page. These are development files, and might not be working at any particular time.
