<p>This document describes the changes made to the Observer
application.</p>
+<section><title>Observer 2.7</title>

+ <section><title>Fixed Bugs and Malfunctions</title>
+ <list>
+ <item>
+ <p>
+ etop.hrl used a relative path to include
+ observer_backend.hrl, this is now changed to use
+ include_lib instead. runtime_tools/include is added to
+ the tertiary bootstrap.</p>

+ <p>
+ If a crashdump was truncated in the attributes section
+ for a module, crashdump_viewer would crash when a module
+ view was opened from the GUI. This bug was introduced in
+ OTP-20.2 and is now corrected.</p>
+ <p>

+ <item>
+ <p>
+ Optimized ets and mnesia table view tab in observer gui,
+ listing 10000 tables was previously very slow.</p>

+ <section><title>Improvements and New Features</title>
+ <list>
+ <item>
+ <p>
+ When a process has many links and/or monitors, it could
+ earlier take very long time to display the process
+ information window. This is now improved by only showing
+ a few links and monitors, and then an link named
+ "more..." to expand the rest.</p>
+ <p>
+ Own Id: OTP-14725</p>
+ </item>
+ <item>
+ <p>
+ More crash dump info such as: process binary virtual heap
+ stats, full info for process causing out-of-mem during
+ GC, more port related info, and dirty scheduler info.</p>
