<h4>JMRI 1.9, 2.0</h4>
The JMRI 1.9 development series moved forward to JRE 1.3, JDK 1.4. This permitted use of:
<ul>
<li>Collections in java.util instead of com.sun</li>
<li>Java2D, along with the associated printing support</li>
<li>Annotations (we need to develop conventions for their use)</li>
<li>JDOM 1.0 - Simplifies XML code, allows use of XSLT for dynamic combination</li>
<li>JUnit 3.8 - Minor improvements to test writing ease</li>
<li>Fewer jar files included in distribution</li>
<li>The Jakarta regexp regular expression library. (At some later point, we'll have to move
that forward to java.util.regexp, but that won't be available until Java 1.4 in a later
JMRI release)</li>
</ul>
<p>JMRI 1.9 and 2.0 will run on Windows 95 and later, all versions of Mac OS X, and all
versions of Linux.</p>
<p>To build JMRI 1.9 and 2.0, you will need Windows 98 1st Ed or later, any version of Mac OS
X, or (almost any?) version of Linux.</p>
<h4>JMRI 2.1, 2.2</h4>
The JMRI 2.1 development series moves forward to JRE 1.4, JDK 1.5. This permits use of
(subject to verification):
<ul>
<li>SwingWorker (and associated updates of threading)</li>
<li>JUnit 4.0</li>
<li>Java3D</li>
<li>JavaHelp update</li>
<li>Drag and Drop</li>
<li>Annotations (we'll have to develop conventions for these)</li>
<li>JavaMail</li>
<li>Java regular expressions (java.util.regexp)</li>
</ul>
<p>JMRI 2.1 and 2.2 will run on Windows 98 1st Ed or later, any version of Mac OS X, or
version of Linux.</p>
<p>To build JMRI 2.1 and 2.2, you will need Windows 98 2nd Ed or later, Mac OS X 10.4 or
later, or (almost any?) version of Linux.</p>
<h4>JMRI 2.3, 2.4</h4>
The JMRI 2.3 development series moves forward to JRE 1.5, JDK 1.5. This permits use of
(subject to verification):
<ul>
<li>JSpinner (and removal of our replacement in jmri.util)</li>
<li>Enums (we'll need to make decisions about interface updates, e.g. Turnout.CLOSED)</li>
<li>printf, Formatter</li>
<li>generics (subject to decisions about conventions and interface updates)</li>
</ul>
<p>JMRI 2.3 and 2.4 will run on Windows 98 2nd Ed or later, Mac OS X 10.4 or later, or
(almost any?) version of Linux.</p>
<p>To build JMRI 2.1 and 2.2, you will need Windows 98 2nd Ed or later, Mac OS X 10.3 or
later, or (almost any?) version of Linux.</p>
<h4>JMRI 2.5, 2.6, 2.7, 2.8</h4>
These versions will continue to use Java 1.5 for both building and running.
<p>During the 2.7 build series, we moved from the Crimson XML parser to Xerces.</p>
<h4>JMRI 2.9, 2.10/3.0</h4>
Plans for the JMRI 2.9 development series are not final.
<p>The JRE and JDK choice for JMRI 2.9 development will depend on desired runtime features,
and availability on our popular user and development platforms. It is <u>tentatively</u> Java
1.5 for both building and running, which is the same as JMRI 2.3.* and following ones.</p>
<p>During the 2.9.* series, we intend to move from the javax.comm serial classes to the RXTX
gnu.io classes, either via RXTX 2.2-pre2 or some later version. This will remove support for
the MS100 from JMRI applications.</p>
<h4>JMRI after Summer 2010</h4>
After JMRI 2.10/3.0 in early summer 2010, development will continue. It's likely that soon
after that, if not before, we'll have to move to using Java 1.6.
<!-- following added from TechRoadMap.shtml December 2015 -->
<h4>JMRI 3.9, 3.10 (End of 2014)</h4>
The JMRI 3.9 development series will stay with Java 1.6 for JRE and SDK.
<h4>JMRI 3.11, 4.0 (Summer 2015)</h4>
For multiple reasons including
<ul>
<li>Improved performance, particularly of web I/O and XML file loading, and</li>
<li>Language and library improvements that made the developer's work easier,</li>
</ul>
the Spring 2015 series of test releases (JMRI 3.11.*) required Java 1.8 for both building and
running. Java 1.8 is also required for the Summer 2015 production release and those that
follow.
<p>Planned JMRI changes that affect backwards-compatibility:</p>
<ul>
<li>Planned removal of XmlIO web service.</li>
<li>Removal of deprecated InstanceManager methods</li>
<li>Removal of some deprecated pass-through classes</li>
</ul>
<p>New library features (subject to verification):</p>
<ul>
<li>Update to JDOM 2 for efficiency and coding convenience</li>
<li>Update Jython to at least 2.5.4 (bug fixes), and depending on compatibility testing,
perhaps 2.7.* (for modern Python)</li>
<li>Start using <a href="https://jcp.org/en/jsr/detail?id=305">JSR 305 annotations</a>
<a href="http://spotbugs.github.io">via SpotBugs</a> to strengthen the code checking (see
<a href="https://today.java.net/pub/a/today/2008/09/11/jsr-305-annotations.html">this</a>
and <a href=
"http://findbugs.sourceforge.net/api/edu/umd/cs/findbugs/annotations/package-summary.html">
this</a>).
