+<h1>Eclipse JDT Photon (4.8) Plug-in Migration Guide</h1>
+<p>This guide covers migrating Eclipse JDT 4.7 plug-ins to Eclipse JDT 4.8.</p>
+<p>One of the goals of Eclipse 4.8 was to move Eclipse forward while remaining compatible
+ with previous versions to the greatest extent possible. That is, plug-ins written
+ against the Eclipse 4.7 APIs should continue to work in 4.8 in spite of the
+ API changes.</p>
+<p>The key kinds of compatibility are API contract compatibility and binary compatibility.
+ API contract compatibility means that valid use of 4.7 APIs remains valid for
+ 4.8, so there is no need to revisit working code. Binary compatibility means
+ that the API method signatures, etc. did not change in ways that would cause
+ existing compiled ("binary") code to no longer link and run with the
+ new 4.8 libraries.</p>
+<p>While every effort was made to avoid breakage, there are a few areas of incompatibility or new
+ APIs that should be adopted by clients.
+ This document describes those areas and provides instructions for migrating 4.7 plug-ins to
+ 4.8.</p>
