This release includes number of fixes for libnghttp2. We briefly explain notable bug fixes here. Previously, libnghttp2 ignored CONTINUATION frames if preceding HEADERS frame contained padding. The appearance of CONTINUATION is rare these days, but padding is used in some services already, and we may see CONTINUATION somewhere too. The second and third bugs are SETTINGS and HPACK dynamic table size related bugs. The second bug is that previously libnghttp2 did not shrink to minimum size of requested dynamic table size contained in SETTINGS frame sent from local endpoint if it contains several SETTINGS_HEADER_TABLE_SIZE. Now it is corrected, and libnghttp2 shrinks to the minimum size. The third bug is that due to the ambiguous text in RFC 7540 and 7541, we interpreted that if receiver received SETTINGS containing SETTINGS_HEADER_TABLE_SIZE, it always has to send dynamic table size update in the next compressed header block. But it turns out that it is not the intention of the specification author. The intended behaviour is the receiver is required to send dynamic table size update only when it really changed maximum dynamic table size. Depending on the SETTINGS_HEADER_TABLE_SIZE and the current maximum dynamic table size, the table size may not change.

Moderncv provides a documentclass for typesetting curricula vitae in
various styles. Moderncv aims to be both straightforward to use and
customizable, providing five ready-made styles (classic, casual,
banking, oldstyle and fancy) and allowing one to define his own by
modifying colors, fonts, icons, etc.
Changelog:
- /Library/TeX/texbin/ has been added to the default path for MacOsX El
Capitan
- the content of the \cite{} command is no more scanned while the spell
checking
- a compilation trouble has been fixed with Qt 5.5.x
- a new option allow the svn users to display the uncommitted lines with
a different color in the line number widget (Configure Texmaker ->
Editor)
- two more options for the pdf internel viewer contextual menu (user
request): number of words in the current pdf page and open the file
browser at the pdf file location
- de, hu, it, nl, pl, se and zh_CN translations have been updated
Special Issues:
* Due to GCC bug 53967, several key agorithms (e.g. convolution) may execute much faster (e.g. 2-3X) for x86-64 and/or when SSE is enabled for floating point math (-mfpmath=sse) if the GCC option -frename-registers is used. Default 32-bit builds do not experience the problem since they use '387 math. It is not clear in what version of GCC this problem started but it was not noticed by the developers until the GCC 4.6 timeframe. Other compilers do not suffer from this bug. Please lobby the GCC project to fix this embarrassing performance bug.
Security Fixes:
* ScaleImage(): While not strictly a security issue, requesting to scale an image while retaining the original number of rows will lead to a program crash or memory corruption due to double-free.
Bug fixes:
* ScaleImage(): Fix problem with new width/height match original (regression added by 1.3.22).
* ScaleImage(): Fix double-free when new rows matches original rows (regression added by 1.3.22).
* MinGW build fix related to eliminating a sleep() macro which conflicts with a MinGW-provided inline sleep() function.
* PNG: Issue a warning instead of an error when attempting to read a PNG file containing a zero-length profile. This allows the file to be read.
* identify: Fix problem in that identify -format "%A" (to test if transparency is supported in image) does not always produce the correct results.
Pkgsrc changes:
* Add a bugfix patch for an LP64 problem in the X11 protocol handling, from
FreeBSD ports tree
* Add a patch to complete initialization of pointers, also from FreeBSD
* Add dependency on libXft, it appears to be required
Upstream changes:
* Add sendToPreviousWorkspace and sendToNextWorkspace functions
* Add new config option: followWindowOnSend, allows bbkeys to change
workspace to the space it just sent a window to
* Fix for underquoted definitions in configure.ac
* Fix annoying behaviour when cycling through windows on all workspaces,
no longer flip workspace when doing this
* Add config option includeIconifiedWindowsInCycle to include iconified
windows in window cycling list
Kodi (formerly known as XBMC) is an award-winning free and open source (GPL)
software media center for playing videos, music, pictures, games, and more.
Kodi features a 10-foot user interface for use with televisions and remote
controls. It allows users to play and view most videos, music, podcasts, and
other digital media files from local and network storage media and the
internet.
for the memoent:
Because multiple versions of wxGTK cannot currently coexist, the
strategy is to use a single version, with each package building with
it if possible and failing otherwise.

CMake 3.4 Release Notes
***********************
Changes made since CMake 3.3 include the following.
New Features
============
Generators
----------
* The :generator:`Visual Studio 14 2015` generator learned to select
a Windows 10 SDK based on the value of the :variable:`CMAKE_SYSTEM_VERSION`
variable and the SDKs available on the host.
* CMake learned rudimentary support for the Apple Swift language. When using
the :generator:`Xcode` generator with Xcode 6.1 or higher, one may enable
the ``Swift`` language with the :command:`enable_language` command or the
:command:`project` command (this is an error with other generators or when
Xcode is too old). Then one may list ``.swift`` source files in targets
for compilation.
Commands
--------
* The :command:`find_program` command learned a ``NAMES_PER_DIR``
option to consider all given ``NAMES`` in each directory before
moving on to the next directory.
* The :command:`get_filename_component` command learned a new ``BASE_DIR``
subcommand. This is used to specify a base directory when calculating an
absolute path from a relative path.
* The :command:`if` command learned a new ``TEST`` operator that evaluates
to true if a given test name has been defined by the :command:`add_test`
command. See policy :policy:`CMP0064`.
* The :command:`install(DIRECTORY)` command ``DESTINATION`` option learned to
support :manual:`generator expressions <cmake-generator-expressions(7)>`.
* The :command:`install(FILES)` command ``DESTINATION`` option learned to
support :manual:`generator expressions <cmake-generator-expressions(7)>`.
* The :command:`string` command learned a new ``APPEND`` subcommand.
Variables
---------
* The :ref:`Makefile Generators` and the :generator:`Ninja` generator
learned to add compiler launcher tools like distcc and ccache along
with the compiler for ``C`` and ``CXX`` languages. See the
:variable:`CMAKE_<LANG>_COMPILER_LAUNCHER` variable and
:prop_tgt:`<LANG>_COMPILER_LAUNCHER` target property for details.
* New :variable:`CMAKE_LINK_SEARCH_START_STATIC` and
:variable:`CMAKE_LINK_SEARCH_END_STATIC` variables were
introduced to initialize the
:prop_tgt:`LINK_SEARCH_START_STATIC` and
:prop_tgt:`LINK_SEARCH_END_STATIC` target properties,
respectively.
Properties
----------
* :ref:`Visual Studio Generators` learned to support additonal
target properties to customize projects for NVIDIA Nsight
Tegra Visual Studio Edition:
* :prop_tgt:`ANDROID_ANT_ADDITIONAL_OPTIONS`
* :prop_tgt:`ANDROID_ARCH`
* :prop_tgt:`ANDROID_ASSETS_DIRECTORIES`
* :prop_tgt:`ANDROID_JAR_DEPENDENCIES`
* :prop_tgt:`ANDROID_JAR_DIRECTORIES`
* :prop_tgt:`ANDROID_JAVA_SOURCE_DIR`
* :prop_tgt:`ANDROID_NATIVE_LIB_DEPENDENCIES`
* :prop_tgt:`ANDROID_NATIVE_LIB_DIRECTORIES`
* :prop_tgt:`ANDROID_PROCESS_MAX`
* :prop_tgt:`ANDROID_PROGUARD`
* :prop_tgt:`ANDROID_PROGUARD_CONFIG_PATH`
* :prop_tgt:`ANDROID_SECURE_PROPS_PATH`
* :prop_tgt:`ANDROID_SKIP_ANT_STEP`
* :prop_tgt:`ANDROID_STL_TYPE`
* The :prop_tgt:`ARCHIVE_OUTPUT_DIRECTORY`,
:prop_tgt:`LIBRARY_OUTPUT_DIRECTORY`, and
:prop_tgt:`RUNTIME_OUTPUT_DIRECTORY` target properties learned to
support :manual:`generator expressions <cmake-generator-expressions(7)>`.
* The :prop_tgt:`SOURCE_DIR` and :prop_tgt:`BINARY_DIR` target properties
were introduced to allow project code to query where a target is defined.
* The :prop_tgt:`OUTPUT_NAME` target property and its variants learned to
support :manual:`generator expressions <cmake-generator-expressions(7)>`.
* A :prop_gbl:`TARGET_MESSAGES` global property was added to tell the
:ref:`Makefile Generators` whether to generate commands to print output
after each target is completed.
* On Windows with MS-compatible tools, CMake learned to optionally
generate a module definition (``.def``) file for ``SHARED`` libraries.
See the :prop_tgt:`WINDOWS_EXPORT_ALL_SYMBOLS` target property.
Modules
-------
* The :module:`ExternalProject` module :command:`ExternalProject_Add`
function ``GIT_SUBMODULES`` option now also limits the set of
submodules that are initialized in addition to the prior behavior
of limiting the set of submodules that are updated.
* The :module:`ExternalProject` module learned new ``USES_TERMINAL``
arguments for giving steps exclusive terminal access. This is
useful with the :generator:`Ninja` generator to monitor CMake
superbuild progress and prevent CPU oversubscription.
* The :module:`FindBISON` module ``BISON_TARGET`` macro learned a
new ``DEFINES_FILE`` option to specify a custom output header
to be generated.

option allowing users to specify that a parallel HDF5 tool is
preferred if both are available.
* The :module:`FindIce` module now provides imported targets.
* The :module:`FindJava` module learned to optionally find
the ``idlj`` and ``jarsigner`` tools.
* The :module:`FindOpenSSL` module now provides imported targets.
* The :module:`FindOpenSSL` module learned a new ``OPENSSL_USE_STATIC_LIBS``
option to search only for static libraries.
* The :module:`FindPkgConfig` learned a new :command:`pkg_get_variable`
command which may be used to query for arbitrary variables from a package
(such as for related tools or data and plugin install paths).
* The :module:`FindProtobuf` module gained a new
:command:`protobuf_generate_python` function to generate python
sources from ``.proto`` files.
* The :module:`FindTIFF` module learned to search separately for
debug and release variants.
* The :module:`FindwxWidgets` module learned to support version requests.
* The :module:`FindXercesC` module learned to search separately for
debug and release variants.
* The :module:`FindZLIB` module learned to search separately for
debug and release variants.
* The :module:`GNUInstallDirs` module learned special default values
for certain installation prefixes according to the `GNU Coding
Standards`_ and the `Filesystem Hierarchy Standard`_.
* The :module:`UseJava` module ``add_jar`` function learned
to support response files (e.g. ``@srcs.txt``) for source
specification.
* The :module:`UseJava` module ``install_jar`` function learned
new ``DESTINATION`` and ``COMPONENT`` options to specify
the corresponding :command:`install` command options.
* The :module:`UseJava` module gained a new ``create_javah``
function to create C headers from Java classes.

.. _`Filesystem Hierarchy Standard`: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html
Generator Expressions
---------------------
* A new ``$<SHELL_PATH:...>``
:manual:`generator expression <cmake-generator-expressions(7)>`
has been added.
CTest
-----
* CTest learned to optionally measure the CPU load during parallel
testing and avoid starting tests that may cause the load to exceed
a given threshold. See the :manual:`ctest(1)` command ``--test-load``
option, the ``TestLoad`` setting of the :ref:`CTest Test Step`,
the :variable:`CTEST_TEST_LOAD` variable, and the ``TEST_LOAD``
option of the :command:`ctest_test` command.
* :manual:`ctest(1)` learned options
``--test-output-size-passed`` and ``--test-output-size-failed``
to customize the limit on test output size submitted when
running as a :ref:`Dashboard Client`.
CPack
-----
* The :module:`CPackDeb` module learned to set package dependencies
per component. See variables:
* :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS`
* :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS`
* :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES`
* :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS`
* :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES`
* :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS`
* :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES`
* :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS`
* The :module:`CPack` module learned to package empty directories.
* The :module:`CPack` module gained a new setting, ``CPACK_VERBATIM_VARIABLES``,
which can be used to ensure the cpack program receives the settings' values
exactly as they were set, even if they contain CMake-special characters.
For compatibility, it's off by default.
Other
-----
* The :manual:`Compile Features <cmake-compile-features(7)>` functionality
is now aware of features supported by GNU C compilers on Windows.
* CMake learned to honor ``*.manifest`` source files with MSVC tools.
Manifest files named as sources of ``.exe`` and ``.dll`` targets
will be merged with linker-generated manifests and embedded in the
binary.
* The `Concurrent Fortran 77 <https://ccur.com>`__ compiler is now supported.
Its :variable:`compiler id <CMAKE_<LANG>_COMPILER_ID>` is ``CCur``.
* :manual:`cmake(1)` gained a new ``--trace-expand`` command line option
that is like ``--trace`` but expands variable references in the output.
Deprecated and Removed Features
===============================
* The :module:`CMakeExpandImportedTargets` module is now documented
as deprecated. See module documentation for an explanation.
* The :variable:`CMAKE_USE_RELATIVE_PATHS` variable no longer has any
effect. Previously it was partially implemented and unreliable.
Other Changes
=============
* The :module:`CheckFunctionExists`, :module:`CheckLibraryExists`,
:module:`CheckSymbolExists`, and :module:`FindThreads` modules learned to
work in environments where only CXX is enabled.
* The :module:`CPackDeb` module now correctly excludes symlinks during package
checksum calculation.
* The :module:`CPackDeb` no longer uses fakeroot and system tar program for
packaging.
* The :module:`CPack` module no longer mangles settings with CMake-special
characters when they're used as defaults for other settings. The macro
``cpack_set_if_not_set``, which was responsible for this, is now deprecated.
* CMake no longer links executables with flags to export symbols
unless the :prop_tgt:`ENABLE_EXPORTS` target property is set.
See policy :policy:`CMP0065`.
* The ``SONAME`` field is no longer set for ``MODULE`` libraries
created with the :command:`add_library` command. ``MODULE``
libraries are meant for explicit dynamic loading at runtime.
They cannot be linked so ``SONAME`` is not useful.
* The internal :variable:`CMAKE_<LANG>_COMPILE_OBJECT` rule variable now
substitutes compiler include flags in a separate ``<INCLUDES>`` placeholder
instead of the main ``<FLAGS>`` placeholder.

3.5.0 (2015-11-13)
==================
Bugs fixed
----------
* Unicode string results failed XPath queries in PyPy.
* LP#1497051: HTML target parser failed to terminate on exceptions
and continued parsing instead.
* Deprecated API usage in doctestcompare.
3.5.0b1 (2015-09-18)
====================
Features added
--------------
* ``cleanup_namespaces()`` accepts a new argument ``keep_ns_prefixes``
that does not remove definitions of the provided prefix-namespace
mapping from the tree.
* ``cleanup_namespaces()`` accepts a new argument ``top_nsmap`` that
moves definitions of the provided prefix-namespace mapping to the
top of the tree.
* LP#1490451: ``Element`` objects gained a ``cssselect()`` method as
known from ``lxml.html``. Patch by Simon Sapin.
* API functions and methods behave and look more like Python functions,
which allows introspection on them etc. One side effect to be aware of
is that the functions now bind as methods when assigned to a class
variable. A quick fix is to wrap them in ``staticmethod()`` (as for
normal Python functions).
* ISO-Schematron support gained an option ``error_finder`` that allows
passing a filter function for picking validation errors from reports.
* LP#1243600: Elements in ``lxml.html`` gained a ``classes`` property
that provides a set-like interface to the ``class`` attribute.
Original patch by masklinn.
* LP#1341964: The soupparser now handles DOCTYPE declarations, comments
and processing instructions outside of the root element.
Patch by Olli Pottonen.
* LP#1421512: The ``docinfo`` of a tree was made editable to allow
setting and removing the public ID and system ID of the DOCTYPE.
Patch by Olli Pottonen.
* LP#1442427: More work-arounds for quirks and bugs in pypy and pypy3.
* ``lxml.html.soupparser`` now uses BeautifulSoup version 4 instead
of version 3 if available.
Bugs fixed
----------
* Memory errors that occur during tree adaptations (e.g. moving subtrees
to foreign documents) could leave the tree in a crash prone state.
* Calling ``process_children()`` in an XSLT extension element without
an ``output_parent`` argument failed with a ``TypeError``.
Fix by Jens Tröger.
* GH#162: Image data in HTML ``data`` URLs is considered safe and
no longer removed by ``lxml.html.clean`` JavaScript cleaner.
* GH#166: Static build could link libraries in wrong order.
* GH#172: Rely a bit more on libxml2 for encoding detection rather than
rolling our own in some cases. Patch by Olli Pottonen.
* GH#159: Validity checks for names and string content were tightened
to detect the use of illegal characters early. Patch by Olli Pottonen.
* LP#1421921: Comments/PIs before the DOCTYPE declaration were not
serialised. Patch by Olli Pottonen.
* LP#659367: Some HTML DOCTYPE declarations were not serialised.
Patch by Olli Pottonen.
* LP#1238503: lxml.doctestcompare is now consistent with stdlib's doctest
in how it uses ``+`` and ``-`` to refer to unexpected and missing output.
* Empty prefixes are explicitly rejected when a namespace mapping is used
with ElementPath to avoid hiding bugs in user code.
* Several problems with PyPy were fixed by switching to Cython 0.23.
