==== Below notes for ====

=== NGrid release notes, "Core v0.7" ===
Date: 2007-05-29
Author: Joannes Vermorel (www.vermorel.com)

NGrid.Core provides a multithreaded and garbage collected 
grid computing framework written in C# and targeting .Net 2.0. 

Only this library is required to actually design (compile and run locally) a distributed application based on NGrid.

Since version 0.5, an NGrid loader is not required
any more to run NGrid-based applications. The NGrid.Zero 
physical grid is loaded by default. In order to use any other grid beside NGrid.Zero, a loader like NGridPlasma is required.


NGrid.Core consists of one assembly with no dependency:
- NGrid.Core.dll

Testing suite succeeds againts .Net 2.0.


=== NGrid notes, "Plasma v0.3" ===
Author: Joannes Vermorel (www.vermorel.com)
Date: 2007-05-29

NGridPlasma is a physical grid to be used in conjunction
with NGrid.Core. NGridPlasma provides a totally decentralized architecture (aka. p2p). NGridPlasma targets CPU intensive applications. The current release is functional yet preliminary. In particular, the load balancing algorithms and distributed garbage collector are still to be fine tuned and fully tested.


The following assemblies are required to run an application
through NGrid.Plasma:
- NGrid.Core.dll (Core v0.7).
- NGridPlasma.exe (Core v0.3).


In order to run an application through the NGridPlasma grid, please look at the documentation.

Testing suite succeeds against .Net 2.0.

== Mono compatibility notes ==

Mono compatibility of this release has not been tested.

Date: 2007-05-29

*** Project layout Changes
* The NGrid.Collection assembly has been merged into NGrid.Core
* All referencies to external assemblies except NUnit have been removed
* The NGrid.Cache assembly is no more part of the NRgid project


=== NGrid changes, "Core v0.6" ===

Date: 2005-11-18

*** Features ***
* IGObjectProxyInterceptor interface extended.

*** Changes ***

* No breaking changes on client side.
* GObjectProxy refactored (now an abstract class).

=== NGrid changes, "Core v0.5" ===
Date: 2005-09-16
Author: Joannes Vermorel (www.vermorel.com)

*** Features ***

The NGrid.Zero physical grid has been added to NGrid.Core.
This "zero" generates virtually no overhead over the non-NGrid
application. In particular, in NGrid.Zero, the GObject are not
proxied.

**** Changes ***

- NGrid.Core has been ported to .Net 2.0 (no change are exploiting
the new feature of the framework for now).

- PartialFormatter, the design has been made more flexible with the
introduction of NGrid.Infrastructure.IGObjectProxyInterceptor.

Date: 2005-09-16
Author: Joannes Vermorel (www.vermorel.com)

*** Features ***
- [Core] GThread local data.

*** Changes ****

- [Core] Numerous modifications suggested by FxCop.
- [Core] IGridServices simplified.
- [Core] IGMonitor simplified.
- [Core] Removed ReplicableAttribute (was redundant).
- [Core] Removed ByValueAttribute (was useless).
- [Core] Large changes in NGrid.Infrastructure.
	- No more needs for custom formatter sinks.
	- Moved from a reference counting to a reference listing scheme.


=== NGrid changes, "Core v0.31" ===
