[Dbappbuilder-relannounce] ANNOUNCE: Rel version 1.0.5 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 two bug fixes:

1. A bug in the way relation literals were parsed allowed the
following...

	RELATION {x INTEGER, y INTEGER} {
		TUPLE {x 1, z 1}
	}

   ...to be accepted and yield:

	RELATION {x INTEGER, y INTEGER} 
		{TUPLE {x 1, y 1}
	}

   This has been corrected.

2. Due to a change in the way the third-party storage engine (Oracle
Berkeley Java DB) generated exceptions -- introduced in Java DB version
4.0.71 -- Rel did not correctly handle an exception related to
transactions and could wind up throwing its own internal exceptions.
This was especially likely when attempting to drop a constraint or
relvar immediately after a Rel error message had been generated.  This
has been corrected.
