LucidDB 0.7.1 release is now available

Download links are available from http://www.luciddb.org, or from
http://sourceforge.net/projects/luciddb.

Note that the LucidDB installer does not yet support upgrade, so be sure
to install the new release in a new location if you already have an old
version installed.  (If anyone needs to upgrade an instance from 0.7.0,
let me know:  a manual procedure exists but hasn't been documented.)

Highlights of the release are

- nested loop join:  allows non-equijoin conditions to be specified for
outer joins, and improves non-equijoin performance for many inner joins

- Mondrian source replication as described here:
http://docs.eigenbase.org/LucidDbMondrianReplication

A number of new documents have also been added (including one on data
storage and access architecture):

Other changes since 0.7.0 include

- new nested loop join feature improves non-equijoin support for
   both inner and outer joins
- fixes in calendar-related applib functions
- VJDBC default connection timeout changed to 1 day
- fixes in rowscan-level filtering when used on the right hand side
   of a cartesian product
- validate to prevent duplicate column references in
   index/constraint definitions
- support for USING clause join conditions
- fix some code caching issues (FRG-263 and others)
- fixes for default value usage (FRG-285)
- fixes for rounding/truncation problems with large BIGINT values
   (avoid usage of intermediate floating point operations)
- fixes for outer join and rowscan row count estimation
- blackhawk and LucidDB test harness improvements
- fixes for bitmap index corruption during incremental loads
- fixes for retrieving distinct DATE/TIME/TIMESTAMP objects via local
   JDBC driver
- suppress revalidation of dependent servers from CREATE OR REPLACE
   WRAPPER
- fix accidental conversion from empty string to NULL (FRG-275)
- avoid preemptive exclusive locking for snapshot-versioned pages
- fix some snapshot-versioned page deallocation problems
