Subject: [Mono-list] Mono 0.20 has been released
The Mono Team introduces the best Mono release so far we have done.
Thanks to everyone who contributed fixes, code, ideas, and bug reports.
Mono 0.20 has been released, it is available at the usual location:
This is a truly heroic release of Mono. Major architectural chunks
that were missing, or were miss-implemented have been fixed in this
release, and we are very proud of it. Please see the list of features,
because there is no short way of introducing just how good this release
is. A big thanks goes to Piers for setting up a Tinderbox that monitors
problems with the Mono CVS repository.
We released packages for SuSE 8.0, Mandrake 8.2, and various Red Hat
releases. It will be made available on the Red Carpet Mono Channel
Source code for Mono, MCS, the Mono Debugger, XSP is available as
well from that web page. The sources are:
MCS package (Class Libraries, C# and VB.NET compiler and managed
Mono package (Runtime engine, JIT compiler):
XSP package (XSP test web server for ASP.NET webforms):

They commited 1810 changes to CVS patches in the past 33 days.
* New in this release
* Zoltan and IKVM
Zoltan's patches to run Jeroen's IKVM (the Java VM that
translates JVM bytecodes into .NET bytecodes) are in. =20
The remoting team's patches that were held off on the previous
release are here. Lluis and Patrik have done a fantastic job
in getting remoting to work. Many low-level runtime engine
changes, and plenty of work on the class-library stuff.
Lluis has posted a couple of sample applications to the
mailing list, you can try those out.
The new release includes a working BinaryFormatter and
BinaryFormatterSink. It means that together with TcpChannel
it is possible to make remote calls with any type of
parameters and return values, including value types,
MarshalByRefObject types (that are properly
marshalled/unmarshalled), delegates, enums, etc.
RemotingConfiguration is partially implemented. It cannot read
from config files, but manual configuration using the api is
Implemented full support for client activated types and for
well known objects (both singleton and single call).
Lease manager fully working (it manages the lifetime of server
Implemented interception of the new operator, so it is
possible to create a remote object using "new", if the type is
properly registered in RemotingConfiguration.
In Lluis' words: `Basically, 0.20 will have almost all needed
for a distributed application with Remoting'
* New threading semantics, IO-layer
Dick Porter in a couple of weeks has heroically redone much of
the threading support to match the .NET behavior (details are
on the .NET threading book as posted on the Mono site).
He also did a lot of bug fixes in the IO/threading space. The
threading implementation now contains a new and faster Monitor
implementation, as well as a correct Pulse()/Wait()
GC thread finalization has been re-enabled. This means that
finalizers will be ran on a separate thread, as done in the
Microsoft.NET Framework. This might expose some bugs on
existing finalizer code.
* Moved to NUnit2
Nick and Gonzalo helped us move to the new NUnit2 platform for=20
all of our tests. A big applause goes to them.
* Cross Appdomain invocations work now.
ASP.NET and NUnit2 both used cross appdomain invocations, we
have fixed a number of problems, and they are now functional.
The AppDomain fixes and the Remoting fixes have allowed us to
remove a number of hacks in the ASP.NET implementation that
were previously there.
Implemented CrossAppDomainChannel, for calls between domains.
* C# Compiler and Debugging.
When generating debugging information in the compiler (with
-debug, -g or -debug+) the compiler will embed the debugging
information into the resulting executable instead of
generating a separate file. Very nice.
Generating debugging information has also improved vastly
performance-wise, and now it is possible to always use
debugging builds for software development.
A number of bugs were fixed on the compiler as well and
by using the Mono profiler we have reduced the memory
consumption and accelerated the compiler.
Thanks to Jackson, Martin, Paolo and for helping here.
* VB.NET Compiler.
Plenty of new features are included in the compiler in our
path to conformance. See <FIXME:get-url-for-posting> for
details on the status of the compiler, and the pieces missing.
* ILasm and Mono.PEToolkit.
Work on the IL assembler has resumed, but it is not yet ready
for production use. The Mono IL Assembler uses the
Mono.PEToolkit library done by Sergey and Jackson to
manipulate CIL image files.
* Cryptographic work.
Sebastien has provided a cert2spc and secutil tools for
certificate management. This is the first release that ships
an assembly for System.Security
Also a new internal assembly used only on Windows allows Mono
users to use the unmanaged crypto providers.
Atsushi has continued to improve the work on our XML
implementation: fixing bugs and more closely matching the
* More PowerPC/Alpha support.
Taylor Christopher has contributed more code generation macros
for PPC and Laramie Leavitt for Alpha.
Gonzalo continued the implementation of our XSLT transformation
API (custom .NET functions are still missing though). It no
longer uses temporary files to apply transformations. Thanks
to an idea from Zdravko Tashev. Xslt Web controls work as
part of this fix.
Gonzalo has cleaned up a lot the code base, and now our test
server supports a --root and --virtual command line options
for better control.=20
Also, now we generate a much nicer error page on errors. We
are looking for volunteers to improve the default look of this
Authentication is now supported
* Mobile Controls.
Gaurav Vaish continues on his quest to complete the
implementation of the Mobile controls. These controls are
required to run a stock IBuySpy application.
* Class Libraries:
New Mono.Posix class library that contains classes for working
on a Posix systems. Things like Unix domain sockets are here.
Alexandre Pigolkine continues to contribute more code to our
Windows.Forms implementation. Currently it only runs on
Windows (or in Linux without GC enabled, due to the
pthread/Wine threading library mismatch. This is being
actively addressed as part of the Wine work due to the
movement to the new thread implementation available in RH 8.1).
* Database providers
Christopher Bockner has updated his DB2 database provider (now
with prepared statement functionality) and Tim Coleman has
continued work on the Oracle database provider (welcome back
* Database code.
Dan Morgan continues to develop core components in System.Data
(and now we welcome Alan Tam to the System.Data core hackers)
The SQL# tool now supports MySQLNet, Npgsql, DB2Client, and
mono --profile now performs memory allocation profiling too.
* Runtime fixes.
We now support multi-module with external file reference
The above in English means that we can now run Eiffel.NET code
More statistics supported now.
Per has contributed the code for this namespace.
Plenty of bugs were closed. =20
