[ANN] Magma 1.0 release 44

[Chris Muller]

I am pleased to announce the immediate availability of Magma 1.0
release "44" for both Squeak, 3.9, 3.10 and Pharo.  Although I am
looking into alternatives for future releases, for now I am still
distributing Magma in my traditional ways:

  - On SqueakMap - three one-click installable packages.

  - In the "1.0r44" Monticello Configuration in the "Magma" project of
squeaksource, there are three one-click installable configurations
(client, server, tester).

  - The "r44Final" Monticello Configuration in the "MagmaTester"
project of squeaksource is the one-click installable MagmaTester
package.

As has always been the case, ONLY ONE of the three packages needs to
be installed, the full and proper configuration is loaded with
one-click.

Compared to r43, this is mostly a maintenance release without any
major new functionality, but with improved robustness in the HA and
luxury querying as well as several other fixes.  Here are the specific
improvements over 43:

	- Made several HA fixes and improvements, many identified by Bart
Gaquie by testing with more than a two-server Magma Node.  Many thanks
Bart.
	- Updated MaQueryExecutor>>#fractionComplete to answer an unreduced
Fraction instead of a reduced one.  This convey's more information;
since the denominator represents the total number of elements in the
final result.  Thanks again to Bart Gauqie.
	- Upgraded MagmaCollectionReader>>#release to allow give a
well-behaved application much freer access to the "luxury" query
features of MagmaCollections.  It is essential for applications
employing luxury query features of Magma for ad-hoc querying, to
#release the Reader returned from the query so that resources on the
server can be freed.
	- Now properly truncating the applied.images file, so it doesn't grow
and grow..
	- Now, when a repository is opened locally, if it's location has
never been set (new repository) or was a different *local* location,
then update it to the new aMagmaLocalLocation.  If it was formerly a
network-hosted server, do not update since we could be here simply
just for re-opening that repository.  So, to go from a remote
repository to a local one, you have to manually update the node's
primaryLocation.
	- Server no longer allows any clients to log in with the system name,
since it is sometimes checked for special-purpose server housekeeping.
	- Updated MagmaSession's standard printing method, again!
	- Added MagmaCollectionReader>>#sortBy:makeDistinct:descending: and
#sortBy:makeDistinct:descending:.
	- Made MaRepositoryDisconnectRequest asynchronous, it now returns
considerably faster!
	- Fix for a recent MagmaCollection optimization.
	- Removed hard-reference to OSProcess.
	- Patch for #removeListener to avoid DependentsArray problem.
	- Fixed a ReadStrategy regression.
