     1.6 +	* Bug #73, modified appendBuffer function to take the srid into
     1.7 +	  consideration even if the argument is a constant (wktLiteral
     1.8 +	  or strdf literal)
     1.9 +
    1.10  	* Update jar references on scripts used by the debian packaging.
    1.11  	  Previously these references pointed only (incorrectly) to
    1.12  	  SNAPSHOTs.
