   * **new associated file urls** - the old way of linking to a document's associated files (eg the original PDF) looked like: //library/sites/<sitename>/collect/<collname>/assoc/<assocfilepath>/doc.pdf//. assocfilepath is based on the identifier of the document, and has the potential to change each time a collection is rebuilt, meaning these links to files are not stable between builds. The new format looks like //library/collection/<collname>/document/<docid>/assoc/doc.pdf// - assocfilepath no longer needed.
+===== Greenstone Extensions =====
+Greenstone has many extensions - projects that add functionality to it. Some are Greenstone3 extensions, which live in the //greenstone3/ext// folder, and can be viewed at [[https://trac.greenstone.org/browser/gs3-extensions]]. Others are Greenstone2 versions - if they relate to collection building then they are suitable for Greenstone 3 also, and would live in //greenstone3/gs2build/ext//. They can be viewed at [[https://trac.greenstone.org/browser/gs2-extensions]].

+=== RSS issues ===
-The RSS button (see [[en:user:rss| the RSS page]] for more information) gives a transformation error. - To fix this please edit web/interfaces/default/transform/gslib.xsl - copy the collNameChecked variable definition from web/interfaces/default/transform/layouts/header-vars.xsl into this file.

+  * If you edit the collectionConfig file to add a plugout line, it gets removed by GLI. Solution: use the import options -saveas and -saveas_options on the Create Pane instead.
+  * Incremental build doesn't update the RSS information with any deletions. Solution: do a full rebuild to remove all the deleted items from the RSS info.
