[James McKelvey]

 I keep getting download errors for  python-sip-6.5.0-1. My Cygwin is otherwise up to date. I've tried multiple repositories.Today it was mirrors.sonic.net.

This release updates Zstandard to the latest upstream version, which is
a maintenance release with minor performance improvements and bugfixes.


Zstandard, or zstd as short version, is a fast lossless compression
algorithm, targeting real-time compression scenarios at zlib-level and
better compression ratios.

http://www.zstd.net/


Besides a standalone compression tool, development headers and a library
with comprehensive API are available both for Cygwin native applications
and cross-compilation toolchains in the following sub-packages:

libzstd-devel-1.5.2-1
libzstd1-1.5.2-1
mingw64-i686-zstd-1.5.2-1
mingw64-x86_64-zstd-1.5.2-1


Notes
-----

This version is compiled with support for GZip, LZ4 and Xz compression
and all libraries are built with MT capability.  Support for legacy
formats from ZStandard versions before 1.0 has been removed.

The openldap package in Cygwin has been updated to the latest upstream
version 2.5.11 (a minor bugfix release).

Notes
=====

The 2.5.x version branch changes the library ABI.  Packages linked
against an earlier libldap ABI need to be recompiled to use this new
version.

Upstream has removed the two database backends that worked at least
partially on Cygwin.  Since they don't support Cygwin (and indeed might
drop the Win32 port at some point), the openldap-server package has been
removed.

This is likely tha last 2.5.x release for Cygwin, the next Cygwin
release will likely be 2.6.1.  The release notes linked to below point
to the 2.6.1 version, which was released upstream in parallel.

This is an update to the latest upstream security and bugfix release of
protobuf.

Protocol Buffers (a.k.a., protobuf) are Google's language-neutral,
platform-neutral, extensible mechanism for serializing structured data.


Note
====

This release is a security release and bumps the ABI versions, packages
that use protobuf should be re-released.

The current upstream release of fetchmail is now available on Cygwin.

The upstream release changelog is here:
https://sourceforge.net/projects/fetchmail/files/branch_6.4/

This release uses the Python3 interpreter and has been compiled with
support for NTLM, GSSAPI authentication, TLSv1.3 is also available.


Note
====

This update fixes regressions and a security bug in the previous
release.

Kerberos5 support has been removed.

This is expected to be the last 6.4.x release for fetchmail, which will
be replaced by the 6.5 or 7.x branch releases if and when they become
available.

A question is asked by NumPy if there is documentation
on the Cygwin package's Cython behavior.
https://github.com/numpy/numpy/pull/20874#issuecomment-1019442058

Does such a document exist?

One of the causes of this issue is a patch
in Cygwin's python-cython package like the one below.
It removes the `__declspec(dllexport)` attribute
from the symbols to be exported.

On the other hand, if you install Cython
by pip without using the Cygwin package,
the exported symbols have the `__declspec(dllexport)` attribute
because the patch has not been applied.

What is the purpose of removing the `__declspec(dllexport)` attribute
in this patch?
Is this to make the modules using Cython
without considering the Cygwin environment,
the module does not have the `__declspec(dllexport)` attribute
like Linux environment, works correctly?

CYGWIN CHANGES

As python2 is no longer supported

https://devguide.python.org/devcycle/#end-of-life-branches

the package are updated to include postinstall script that
use "alternatives" to define for

  /usr/bin/python

  /usr/bin/python3
  /usr/bin/idle3
  /usr/bin/pydoc3

a default to the highest package available.

$ alternatives --display python
python - status is auto.
  link currently points to /usr/bin/python3.9
/usr/bin/python2.7 - priority 27
/usr/bin/python3.6 - priority 36
/usr/bin/python3.7 - priority 37
/usr/bin/python3.8 - priority 38
/usr/bin/python3.9 - priority 39
Current `best' version is /usr/bin/python3.9.

The following link are not provided anymore.
/usr/bin/idle
/usr/bin/pydoc

Rationale:
https://www.python.org/dev/peps/pep-0394/
In other systems as Debian
/usr/bin/python is discouraged.

As on Cygwin we have still several third packages depending on
python2, the usage of alternatives should allow to manage
until all are updated to python3

DESCRIPTION
Python is a programming language that lets you work quickly
and integrate systems more effectively.
Python is powerful... and fast; plays well with others;
runs everywhere; is friendly & easy to learn; is Open.

Hi James,

python-sip is an obsolete empty package

you are probably looking for python3X-sip (with X 6, 7, 8 or 9)

Thanks for reporting this.

It's a bug in setup that it's trying to download this package which 
doesn't actually exist.

This should be resolved by setup 2.917
