[ANN] Release of eXist 3.1.1

(Apologies for cross-posting.)

eXist-db v3.1.1 was released today. This release primarily addresses bugs
fixed since the release of v3.1.0 earlier this month.  As detailed at
http://exist-db.org/exist/apps/wiki/blogs/eXist/eXistdb311, the most
important changes are:

   - fixed command line parameters for backup/restore and the Java admin
   client (partially broken in 3.1.0)
   - closed memory leak in XQuery map constructor
   - closed memory leak preventing memory used for accessing binary
   resources in XQuery being freed
   - added missing dependencies for YAJSW when installing as a System-V
   service
   - corrected fn:doc-available() to return false(), not FODC0005, when it
   cannot the remote resource does not return a document node
   - prevented an NPE when an account or a group can't be found by id due
   to storage corruption or a missing account or group

In addition, this release includes updated versions of a number of the
bundled applications: Documentation (v0.4.8), Monitoring and Profiling AKA
"Monex" (v0.9.7), Shared Resources (v0.4.2). Other applications updated
since the last release of eXist-db include Demo Apps (v0.4.0), Public
Application Repository (v0.6.0), and XQuery Versioning Module (v1.1.2). The
updated versions and their release notes are all available via the eXist-db
Dashboard > Package Manager or from the eXist-db Public Application
Repository <http://demo.exist-db.org/exist/apps/public-repo/index.html>.
