I compiled a more detailed list of changes and status for cygports:

A diff of the modules from 5.8 to 5.10 is below.
Module::Build is definitely now in CORE.

completely new in 5.10:
Archive::Extract
Config::Extensions
CPANPLUS
Hash::Util::FieldHash
POSIX::SigRt
Time::Piece
encoding::warnings
ExtUtils::Constant::ProxySubs
Devel::InnerPackage
feature
File::Fetch
Log::Message
Module::Build
Module::CoreList
Module::Load
Module::Loaded
Module::Pluggable
mro
Object::Accessor
Package::Constants
Params::Check
Term::UI
Tie::Hash::NamedCapture
Tie::StdHandle

vendor->CORE:
Archive::Tar
Compress::Zlib
Win32API::File
Math::BigInt::FastCalc
ExtUtils::CBuilder
ExtUtils::ParseXS
File::Temp
Compress::Raw::Zlib
IO::Zlib
IPC::Cmd
Pod::Escapes
Pod::Simple
version

removed:
ByteLoader
B::Stackobj
B::Disassembler
B::C, ... The whole compiler is gone from CORE.
XS::APItest
XS::Typemap
dbm_filter_util
Test::Deep
Test::Tester

The complete filelist is at 
http://rurban.xarch.at/cygr/perl/perl-5.10.0-1.lst
the old one at http://rurban.xarch.at/cygr/perl/perl-5.8.8-4.lst

It is in steady testing since summer (5.9.5), and
the final release is tested daily with about 400 additional CPAN
modules so far.

I'm quite busy submitting patches to the tracker for the more 
complicated Devel and B packages which are not yet 5.10 ready. 
B::Generate and B::Lint works now, but the B compiler was removed
from CORE.
Andy Koenig tested about 1500 modules last week.
Jerry Hedden does a lot of cygwin testing also.
My XML::LibXML bugfixes are still not accepted upstream, so
it's in vendor. This is quite important for GNOME.

I believe we will be ready to switch in about 2-3 weeks or so.
