<title>Postselector</title>
<para>The Postselector has been refactored out of existence.
Its responsibilities have been parcelled out to two new Processors:
LinksScoper and FrontierScheduler. LinksScoper is responsible for
scope checking of extracted links. FrontierScheduler does the
scheduling of URIs with the Frontier.
</para>
<para>This change was done to allow introduction of processors
between scope checking and Frontier scheduling steps.
</para>
<para>Because of this change, order files from 1.4.0 Heritrix or
before will need to be updated -- Postselector references replaced
by LinkScoper and FrontierScheduler references -- before they
can be used with Heritrix 1.6.0 (Referencing a non-existent
Postselector in an order file usually shows as -50 fetch status
in crawl.log).
