Release Notes for JMRI 4.9.3 release

Date: August 20, 2017

From: Bob Jacobsen

Subject: Test Release 4.9.3 of JMRI/DecoderPro is available for download.

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 around the end of 2017. (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.

Required Migration StepSince JMRI 4.7.4

JMRI was updated in JMRI 4.7.4 to use a new serial library. Depending on your exact circumstances, you may need to do some migrations:

Known problems with this release

New warnings for this release:

Older warnings

See the JMRI 4.8 release note for more warnings predating the 4.8 development series. These may be relevant to you if you're updating from an earlier version.

Since JMRI 4.7.6 If you're having trouble getting your DCC programmer to work, try checking that the "Defaults" under "Preferences" are set to your hardware system. The reason: This version of JMRI (and all later) provides more options for "default systems": If you have multiple sets of hardware attached, which should be used for throttles, for programming, etc. JMRI tries to guess the right settings for these when you upgrade to this version, but apparently it sometimes gets that wrong (we haven't been able to track that down yet). Setting them manually fixes any wrong guesses.

Since JMRI 4.7.5 This version of JMRI (and all later) writes a slightly streamlined version of panel file contents. Older files should still be readable by this version of JMRI, but files written by this version may not be readable by versions before JMRI 4.2 depending on their contents.

Since JMRI 4.7.5 The LocoNetOverTCP server has changes that may break scripts that reference it. Scripts refering to the class jmri.jmrix.loconet.loconetovertcp.Server need to refer instead to jmri.jmrix.loconet.loconetovertcp.LnTcpServer.

Since JMRI 4.7.3 This release will not start cleanly if installed over earlier versions of JMRI (the Windows installer ensures this is not an issue). Remove the JAR files jackson-annotations-2.0.6.jar, jackson-core-2.0.6.jar, and jackson-databind-2.0.6.jar from the lib directory within the previous installation directory to resolve this.

Since JMRI 4.7.1 JMRI no longer supports the portable paths resource: or file: that were deprecated in JMRI 2.13. When loading a panel, an error message will be displayed if the panel contains a path that starts with resource: and the panel will not load until changed using an external editor. Paths starting with file: cannot be automatically flagged because JMRI allows file: URLs.

Since JMRI 4.7.1 The LocoNet Server (the LocoNetRMI service; not the LocoNetOverTcp service) in this version of JMRI doesn't properly interoperate with JMRI 4.7.1 through JMRI 4.7.4. It does work fine with JMRI version 4.6 or before. If you encounter a problem with version compatibility, you'll see an error message that includes "local class incompatible". The workaround is to update both client and server JMRI machines to the same JMRI version.

Since JMRI 4.7.1 JMRI applications will not load a panel file that fails XML validation; an error will be shown that should explains the error, allowing it to be fixed using an editor. (The explanations remain a work in progress.) If you have a problem loading a panel file, please
