Production-ready binary distributions based on the JDK 7 code base are available now from <a href="http://oracle.com/technetwork/java/javase/downloads">Oracle</a> and will be available soon in most <a href="/install">Linux distributions</a> and from Oracle's <a href="http://java.sun.com/javase/licensees.jsp">Java SE licensees</a>.</p> <p>Detailed information on the main features of the release can be found on the <a href="features">features</a> page. The JDK 7 development schedule was divided into a sequence of <a href="milestones">milestone cycles</a>. A complete <a href="calendar">calendar</a> of the entire development timeline is also available.</p> <p>Development of JDK 7 update releases is being done in the nearby <a href="../jdk7u">JDK 7 Updates Project</a>.</p> <h2>History</h2> <p>After Oracle acquired Sun we replanned JDK 7 according to the <a href="http://mreinhold.org/blog/plan-b">"Plan B"</a> proposal in order to accelerate its release while maintaining performance and quality. Features that needed more time to mature were deferred to JDK 8 or later releases as explained <a href="http://mreinhold.org/blog/rethinking-jdk7">here</a>. A handful of small, high-impact features which were not previously part of the plan but were finished, or nearly so, were added to the release.</p> <p>The high-level schedule for the endgame of the release was as follows:</p> <blockquote> <table class="sched"> <tr> <td rowspan="1" colspan="1">2010/12/23</td> <td rowspan="1" colspan="1">Feature Complete (M11)</td> </tr> <tr> <td rowspan="1"
