pkgsrc changes:
- Switch MASTER_SITES to https://www.python.org/ftp/python/doc/${VERS}/
Unlike previous MASTER_SITES the documentation there is not regenerated
periodically (so it will avoid possible changes in the distfiles).
Changes (from the `Documentation' section of the Python 3.5.3 Changelog):
- Issue #28513: Documented command-line interface of zipfile.
MASTER_SITES= site1 \
site2
style continuation lines to be simple repeated
MASTER_SITES+= site1
MASTER_SITES+= site2
lines. As previewed on tech-pkg. With thanks to rillig for fixing pkglint
accordingly.

removed. They had been available in the platform specific Lib/plat-*/
directories, but were chronically out of date, inconsistently available across
platforms, and unmaintained. The script that created these modules is still
available in the source distribution at Tools/scripts/h2py.py.
No PKGREVISION bump since they failed to install on these platforms.
TODO: PLIST.IRIX entries seems to still contains plat-* modules but the ones
TODO: contained are not explicitly documented in the changelog, so they can
TODO: maybe still installed.
Pointed out by Joyent's Linux and SmartOS bulk builds and thanks to <jperkin>
for testing it!
pkgsrc changes:
- Switch MASTER_SITES to https://www.python.org/ftp/python/doc/${VERS}/
Unlike previous MASTER_SITES the documentation there is not regenerated
periodically (so it will avoid possible changes in the distfiles).
Changes:
Unfortunately no changelog is available. However, the documentation
is now synced with the lang/python34 version available in pkgsrc.

What's New in Python 3.4.6?
===========================
Release date: 2017-01-16
There were no changes between 3.4.6rc1 and 3.4.6 final.
What's New in Python 3.4.6rc1?
==============================
Release date: 2017-01-02
Core and Builtins
-----------------
- Issue #28648: Fixed crash in Py_DecodeLocale() in debug build on Mac OS X
when decode astral characters. Patch by Xiang Zhang.
- Issue #28426: Fixed potential crash in PyUnicode_AsDecodedObject() in debug
build.
Library
-------
- Issue #28563: Fixed possible DoS and arbitrary code execution when handle
plural form selections in the gettext module. The expression parser now
supports exact syntax supported by GNU gettext.
- In the curses module, raise an error if window.getstr() or window.instr() is
passed a negative value.
- Issue #27783: Fix possible usage of uninitialized memory in operator.methodcaller.
- Issue #27774: Fix possible Py_DECREF on unowned object in _sre.
- Issue #27760: Fix possible integer overflow in binascii.b2a_qp.
- Issue #27758: Fix possible integer overflow in the _csv module for large record
lengths.
- Issue #27568: Prevent HTTPoxy attack (CVE-2016-1000110). Ignore the
HTTP_PROXY variable when REQUEST_METHOD environment is set, which indicates
that the script is in CGI mode.
- Issue #27759: Fix selectors incorrectly retain invalid file descriptors.
Patch by Mark Williams.
Build
-----
- Issue #28248: Update Windows build to use OpenSSL 1.0.2j.
Tests
-----
- Issue #27369: In test_pyexpat, avoid testing an error message detail that
changed in Expat 2.2.0.
The previous commit ended up with two different specifications for libtool
on Darwin. One was the OS-specific version of CMAKE_ARGS introduced in the
previous commit; the other was inside a conditional to detect Darwin introduced in the commit prior. The former seems cleaner so it has been left.
Changelog:
Changes from 4.1.3 to 4.1.4
---------------------------
1. Updated to GNU autoconf 2.69, automake 1.15, gettext 0.19.7,
texinfo 6.1, texinfo.tex 2016-02-05.07, libtool 2.4.6.
2. z/OS support updated.
3. At the beginning of each statement, the debugger now checks and
reports watchpoints that have fired before checking for breakpoints.
This gives more natural behavior to the user.
4. The "exit" command has been added to the debugger as an alias
for "quit".
5. AIX 7.1 should pass the test suite now. Similar for Minix.
6. VMS support has been updated.
7. The profiler / pretty-printer now chains else-if statements instead
of causing cascading elses.
8. The return value of system() has been enhanced to convey more information.
See the doc.
9. Attempting to write to the "to" end of a two-way pipe that has been
closed is now a fatal error. Similarly, so is reading from the "from"
end that has been closed.
10. MinGW support has been updated.
11. The -d option now allows -d- to print to standard output.
12. Error messages for --help and in other instances should now get
translated correctly.
13. A new environment variable GAWK_LOCALE_DIR may be set to locate the .mo
file for gawk itself.
14. The DJGPP port is now officially deprecated.
15. A number of bugs have been fixed. See the ChangeLog.
this to build for NetBSD/powerpc:
* need a cast in one place (in the renamed patch)
* an overcautious assert() is incompatible with top/down VM layout in NetBSD
This still doesn't work on NetBSD/powerpc, though, and I ran out of time.
The build produces a mono-boehm.core file the first time through the build
(for some reason not the subsequent attempts, sigh!), and I have problems
reconstructing the CLI to run the mono-boehm executable under gdb, and the
core file says it got a segv in opendir() which must be nonsensical.
This is a special release that contains 0 commits. While promoting
additional platforms for v6.9.3 after the release, the tarballs on the
release server were overwritten and now have different shasums. In order
to remove any ambiguity around the release we have opted to do a semver
patch release with no changes.

The LLVMContext gains a new runtime check (see LLVMContext::discardValueNames()) that can be set to discard Value names (other than GlobalValue). This is intended to be used in release builds by clients that are interested in saving CPU/memory as much as possible.
There is no longer a “global context” available in LLVM, except for the C API.
The autoconf build system has been removed in favor of CMake. LLVM 3.9 requires CMake 3.4.3 or later to build. For information about using CMake please see the documentation on Building LLVM with CMake. For information about the CMake language there is also a CMake Primer document available.
C API functions LLVMParseBitcode, LLVMParseBitcodeInContext, LLVMGetBitcodeModuleInContext and LLVMGetBitcodeModule having been removed. LLVMGetTargetMachineData has been removed (use LLVMGetDataLayout instead).
The C API function LLVMLinkModules has been removed.
The C API function LLVMAddTargetData has been removed.
The C API function LLVMGetDataLayout is deprecated in favor of LLVMGetDataLayoutStr.
The C API enum LLVMAttribute and associated API is deprecated in favor of the new LLVMAttributeRef API. The deprecated functions are LLVMAddFunctionAttr, LLVMAddTargetDependentFunctionAttr, LLVMRemoveFunctionAttr, LLVMGetFunctionAttr, LLVMAddAttribute, LLVMRemoveAttribute, LLVMGetAttribute, LLVMAddInstrAttribute, LLVMRemoveInstrAttribute and LLVMSetInstrParamAlignment.
TargetFrameLowering::eliminateCallFramePseudoInstr now returns an iterator to the next instruction instead of void. Targets that previously did MBB.erase(I); return; now probably want return MBB.erase(I);.
SelectionDAGISel::Select now returns void. Out-of-tree targets will need to be updated to replace the argument node and remove any dead nodes in cases where they currently return an SDNode * from this interface.
Added the MemorySSA analysis, which hopes to replace MemoryDependenceAnalysis. It should provide higher-quality results than MemDep, and be algorithmically faster than MemDep. Currently, GVNHoist (which is off by default) makes use of MemorySSA.
The minimum density for lowering switches with jump tables has been reduced from 40% to 10% for functions which are not marked optsize (that is, compiled with -Os).

Notable Changes

- Allow obvious key/passphrase combinations.
url:
- Including base argument in URL.originFor() to meet specification
compliance.

Erlang/OTP 19.2 is the second service release for the 19 major release.
The service release contains mostly bug fixes and characteristics
improvements.
Some highlights for 19.2
* STDLIB: The new behaviour gen_statem has been improved with 3 new
features: the possibility to use old style non-proxy timeouts
for gen_statem:call/2,3, state entry code, and state
timeouts. These are backwards compatible. Minor code and
documentation improvements has been performed including a
borderline semantics correction of timeout zero handling.
* SSL: Experimental version of DTLS. It is runnable but not complete
and cannot be considered reliable for production usage. To use
DTLS add the option {protocol, dtls} to ssl:connect and ssl:listen.
* SSH: Extended the option silently_accept_hosts for ssh:connect to
make it possible for the client to check the SSH host key
fingerprint string. Se the reference manual for SSH.
* ~40 contributions since the previous service release OTP 19.1

service release at
