Hello,

I'd like to announce the release of my DBI proxy DBD::pNET, version
0.1003. A DBI proxy is useful if your database doesn't support
network access, but the primary goal is the use of databases that
run behind firewalls.

User visible changes are:

  - Query restrictions; this means you can create a list of queries
    on the server, say

	foo_insert => INSERT INTO foo VALUES (?, ?)
	foo_delete => DELETE FROM foo WHERE id = ?
	foo_select => SELECT * FROM foo WHERE date >= ?

    and execute them on the client by using the fake SQL statement

	$sth->do("foo_insert (?, ?)", $id, $date);

    Access is restricted to these queries, which is of special
    importance in a firewalled environment.

  - Binding parameters; you'll note that this is used in the
    above example, but it wasn't supported by pNET so far;
    my thanks to Taner Halicioglu <taner@isi.net> for forcing me
    to introduce this feature. :-)

  - a few minor bug fixes; I received suprisingly few bug reports
    and most of them have been tracked down to the "Storable"
    module that pNET is based on. Due to my past experiences I
    suppose this means that pNET isn't wide spreadily used ... :-)


Bye,

Jochen
