[Dbappbuilder-relannounce] ANNOUNCE: Rel version 1.0.9 Beta released

[Rel a. list. <dba...@li...>]

This version of /Rel/ -- an implementation of Date & Darwen's *Tutorial 
D* database language -- is a maintenance release featuring various 
enhancements and bug fixes:

- Fix: Unicode support is now explicitly provided in /Rel/, DBrowser,
   and the RelClient middleware.  This should reduce the likelihood of
   errors or incorrect character translations when inputting unicode
   characters.

- Fix: /Rel/: A problem emitting escaped characters (special characters
   prefixed with a backslash, e.g., '\t') has been corrected, so that
   (for example) repeatedly backed up and restored Rel databases will
   no longer exhibit a harmless but awkward repetition of backslashes
   in certain string values.  E.g., names like "O\\\\\\\\\\\\\\'Neil"
   should no longer occur.

- Fix: /Rel/: Replaced reference to
   "ca.mb.armchair.rel3.values.ValueChar" with
   "ca.mb.armchair.rel3.values.ValueCharacter" in
   ForeignCompilerJava.java.  This fixes problems creating new
   Java-based types which define methods/operators that use CHAR
   parameters.

- Enhancement/Fix: RelTest: Test suite has been redesigned to support
   execution of tests in random order.

- Enhancement/Fix: /Rel/: Updated to version 5.0.34 of Berkeley Java DB.
   As a side-effect of implementing this, occasional database
   corruptions leading to crashes -- typically referring to duplicate
   btree keys and the like -- should no longer occur.

- Enhancement: /Rel/: Temporary internal buffering of relations now
   dynamically switches from in-memory to disk-based storage based on
   cardinality.  This will improve performance on low-cardinality
   queries whilst supporting very high cardinality queries.

- Enhancement: /Rel/: Implemented mechanism to ensure expected version
   of Berkeley Java DB is installed.  This eliminates possible errors
   due to running an incompatible version of the Berkeley Java DB.

- Enhancement: Scripts: TypeDate.d now implements THE_readable, which
   obtains a human-friendly date.

- Enhancement: /Rel/: Improved speed of compiling Java-based types and
   operators.

- Enhancement: DBrowser: Crashes will now automatically open a dialog
   box to allow the user to send an error report to the developers.
