   * **the recommended "//PDFv2Plugin//"**, which will contain the new functionality and should handle a greater range of PDF versions, including the newer ones that the old ''pdftohtml'' (now used by PDFv1Plugin) can't handle. The "PDFBox conversion" facility has been moved to the new PDFv2Plugin, but is now invisible: it will be triggered automatically depending on the "convert_to" format that you select when you Configure the PDFv2Plugin. PDFv2Plugin also uses additional conversion tools in the background to support the additional output formats.
-For the eventual 3.09 release, the old PDFPlugin that you're familiar with, the one which has the ''pdfbox_conversion'' flag but also makes use of the old ''pdftohtml'' tool behind the scenes, will hang around with a deprecated warning, to allow people to port over their collections and keep rebuilding with the old settings or to rebuild their collection with one of the 2 new PDF plugins. However, **new collections will have the //PDFv2Plugin// in the Document Plugins pipeline by default, for GS3, and PDFv1Plugin by default for GS2, since GS2 doesn't come with the PDFbox extension out of the box.** So GS2 users will have to manually add in PDFv2Plugin in place of PDFv1Plugin for new collections, after setting up the pdfbox extension. But then it should work as usual.

 - install a newer version of Java on your system. We found that the current latest one, 1.8.0_191 worked successfully for this purpose.
+=== SIGPIPE errors when building a collection ===
+We've added a work around to one kind of SIGPIPE errors which could occur with large collections when using ''solr'' as indexer. However, a couple of people on the mailing list encountered SIGPIPE errors on occasions when solr was not the indexer. **If your collection is using ''jdbm'' as the database type** and the error messages surrounding the SIGPIPE mention issues with "transaction commit", then Mariana Pichinini on the mailing list found that the following helped:
+  * change the database type from ''jdbm'' to ''gdbm''
+  * or leave the database type at ''jdbm'' and move your GS3's bundled JRE (the GS3's ''packages/jre'' subfolder) outside your GS3 installation. Next install a newer Java on your system so that GS3.08 can find that. If on Linux, ensure you open a new terminal before running GLI or command line building your collection.
