+<h1>Eclipse 2020-09 (4.17) Plug-in Migration Guide</h1>
+<p>This guide covers migrating Eclipse 4.15 plug-ins to Eclipse 4.17.</p>
+<p>One of the goals of Eclipse 4.17 was to move Eclipse forward while remaining compatible
+ with previous versions to the greatest extent possible. That is, plug-ins written
+ against the Eclipse 4.15 APIs should continue to work in 4.17 in spite of any API changes.</p>
+<p>The key kinds of compatibility are API contract compatibility and binary compatibility.
+ API contract compatibility means that valid use of 4.15 APIs remains valid for
+ 4.17, 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 4.17 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.
+ These documents describe those areas and provide instructions for migrating 4.15 plug-ins to
+ 4.17.</p>
