A composable cycle class used for constructing style-cycles.
Feature release for cycler. This release includes a number of new
features:
Cycler objecst learned to generate an itertools.cycle by calling them,
a-la a generator.
Cycler objects learned to change the name of a key via the new
.change_key(old_key, new_key) method.
Cycler objects learned how to compare each other and determine if they
are equal or not (==).
Cycler objects learned how to join another Cycler to be concatenated
into a single longer Cycler via concat method of function. A.concat(B)
or concat(A, B).
The cycler factory function learned to construct a complex Cycler from
iterables provided as keyword arguments.
Cycler objects learn do show their insides with the by_key method which
returns a dictionary of lists (instead of an iterable of dictionaries).
# `pydot` changelog
## 1.2.0 (2016-07-01)
- Python 3 compatibility
- bumped dependency to `pyparsing >= 2.1.4`
- tests running on Travis CI
- tests require `chardet`
- detect character encoding for most test files
using the package `chardet`
API:
- on all operating systems, search GraphViz
executables in environment `$PATH`,
using `subprocess.Popen`.
No paths hard-coded due to security and privacy issues.
- add option to pass GraphViz executable name
or absolute path as `prog` to `pydot.Dot.write_*` methods.
This provides an alternative to
adding GraphViz to the `$PATH`.
- the functions:
- `pydot.graph_from_dot_data`
- `pydot.graph_from_dot_file`
- `dot_parser.parse_dot_data`
changed to always return a `list` of graphs,
instead of behaving differently for singletons.
- require that the user explicitly give an encoding to
the function `pydot.graph_from_dot_file`,
with default encoding same as `io.open`.
- decode to unicode at program boundaries, and
treat binary images as bytes,
for more compatibility with python 3.
Use `io.open`, instead of the built-in `open`.
- rm function `pydot.set_graphviz_executables`
- rm attribute `pydot.Dot.progs`
## 1.1.0 (2016-05-23)
- compatibility with `pyparsing >= 1.5.7`
API:
- `pydot.Graph.to_string`: hide `subgraph` keyword only if so requested
- produce `warnings.warn` if `pydot.dot_parser` fails to import,
instead of `print`
## 1.0.29 (2016-05-16)
- Maintenance release that keeps the same API
- pin `pyparsing == 1.5.7`
- update version number in source code
- update `setup.py`
==========
Change Log
==========
Version 2.1.8 -
------------------------------
- Fixed issue in the optimization to _trim_arity, when the full
stacktrace is retrieved to determine if a TypeError is raised in
pyparsing or in the caller's parse action. Code was traversing
the full stacktrace, and potentially encountering UnicodeDecodeError.
- Fixed bug in ParserElement.inlineLiteralsUsing, causing infinite
loop with Suppress.
- Fixed bug in Each, when merging named results from multiple
expressions in a ZeroOrMore or OneOrMore. Also fixed bug when
ZeroOrMore expressions were erroneously treated as required
expressions in an Each expression.
- Added a few more inline doc examples.
- Improved use of runTests in several example scripts.
Version 2.1.7 -
------------------------------
- Fixed regression reported by Andrea Censi (surfaced in PyContracts
tests) when using ParseSyntaxExceptions (raised when using operator '-')
with packrat parsing.
- Minor fix to oneOf, to accept all iterables, not just space-delimited
strings and lists. (If you have a list or set of strings, it is
not necessary to concat them using ' '.join to pass them to oneOf,
oneOf will accept the list or set or generator directly.)
Version 2.1.6 -
------------------------------
- *Major packrat upgrade*, inspired by patch provided by Tal Einat -
many, many, thanks to Tal for working on this! Tal's tests show
faster parsing performance (2X in some tests), *and* memory reduction
from 3GB down to ~100MB! Requires no changes to existing code using
packratting. (Uses OrderedDict, available in Python 2.7 and later.
For Python 2.6 users, will attempt to import from ordereddict
backport. If not present, will implement pure-Python Fifo dict.)
- Minor API change - to better distinguish between the flexible
numeric types defined in pyparsing_common, I've changed "numeric"
(which parsed numbers of different types and returned int for ints,
float for floats, etc.) and "number" (which parsed numbers of int
or float type, and returned all floats) to "number" and "fnumber"
respectively. I hope the "f" prefix of "fnumber" will be a better
indicator of its internal conversion of parsed values to floats,
while the generic "number" is similar to the flexible number syntax
in other languages. Also fixed a bug in pyparsing_common.numeric
(now renamed to pyparsing_common.number), integers were parsed and
returned as floats instead of being retained as ints.
- Fixed bug in upcaseTokens and downcaseTokens introduced in 2.1.5,
when the parse action was used in conjunction with results names.
Reported by Steven Arcangeli from the dql project, thanks for your
patience, Steven!
- Major change to docs! After seeing some comments on reddit about
general issue with docs of Python modules, and thinking that I'm a
little overdue in doing some doc tuneup on pyparsing, I decided to
following the suggestions of the redditor and add more inline examples
to the pyparsing reference documentation. I hope this addition
will clarify some of the more common questions people have, especially
when first starting with pyparsing/Python.
- Deprecated ParseResults.asXML. I've never been too happy with this
method, and it usually forces some unnatural code in the parsers in
order to get decent tag names. The amount of guesswork that asXML
has to do to try to match names with values should have been a red
flag from day one. If you are using asXML, you will need to implement
your own ParseResults->XML serialization. Or consider migrating to
a more current format such as JSON (which is very easy to do:
results_as_json = json.dumps(parse_result.asDict()) Hopefully, when
I remove this code in a future version, I'll also be able to simplify
some of the craziness in ParseResults, which IIRC was only there to try
to make asXML work.
- Updated traceParseAction parse action decorator to show the repr
of the input and output tokens, instead of the str format, since
str has been simplified to just show the token list content.
(The change to ParseResults.__str__ occurred in pyparsing 2.0.4, but
it seems that didn't make it into the release notes - sorry! Too
many users, especially beginners, were confused by the
"([token_list], {names_dict})" str format for ParseResults, thinking
they were getting a tuple containing a list and a dict. The full form
can be seen if using repr().)
For tracing tokens in and out of parse actions, the more complete
repr form provides important information when debugging parse actions.
Verison 2.1.5 - June, 2016
------------------------------
- Added ParserElement.split() generator method, similar to re.split().
Includes optional arguments maxsplit (to limit the number of splits),
and includeSeparators (to include the separating matched text in the
returned output, default=False).
- Added a new parse action construction helper tokenMap, which will
apply a function and optional arguments to each element in a
ParseResults. So this parse action:
def lowercase_all(tokens):
return [str(t).lower() for t in tokens]
OneOrMore(Word(alphas)).setParseAction(lowercase_all)
can now be written:
OneOrMore(Word(alphas)).setParseAction(tokenMap(str.lower))
Also simplifies writing conversion parse actions like:
integer = Word(nums).setParseAction(lambda t: int(t[0]))
to just:
integer = Word(nums).setParseAction(tokenMap(int))
If additional arguments are necessary, they can be included in the
call to tokenMap, as in:
hex_integer = Word(hexnums).setParseAction(tokenMap(int, 16))
- Added more expressions to pyparsing_common:
. IPv4 and IPv6 addresses (including long, short, and mixed forms
of IPv6)
. MAC address
. ISO8601 date and date time strings (with named fields for year, month, etc.)
. UUID (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
. hex integer (returned as int)
. fraction (integer '/' integer, returned as float)
. mixed integer (integer '-' fraction, or just fraction, returned as float)
. stripHTMLTags (parse action to remove tags from HTML source)
. parse action helpers convertToDate and convertToDatetime to do custom parse
time conversions of parsed ISO8601 strings
- runTests now returns a two-tuple: success if all tests succeed,
and an output list of each test and its output lines.
- Added failureTests argument (default=False) to runTests, so that
tests can be run that are expected failures, and runTests' success
value will return True only if all tests *fail* as expected. Also,
parseAll now defaults to True.
- New example numerics.py, shows samples of parsing integer and real
numbers using locale-dependent formats:
4.294.967.295,000
4 294 967 295,000
4,294,967,295.000
Version 2.1.4 - May, 2016
------------------------------
- Split out the '==' behavior in ParserElement, now implemented
as the ParserElement.matches() method. Using '==' for string test
purposes will be removed in a future release.
- Expanded capabilities of runTests(). Will now accept embedded
comments (default is Python style, leading '#' character, but
customizable). Comments will be emitted along with the tests and
test output. Useful during test development, to create a test string
consisting only of test case description comments separated by
blank lines, and then fill in the test cases. Will also highlight
ParseFatalExceptions with "(FATAL)".
- Added a 'pyparsing_common' class containing common/helpful little
expressions such as integer, float, identifier, etc. I used this
class as a sort of embedded namespace, to contain these helpers
without further adding to pyparsing's namespace bloat.
- Minor enhancement to traceParseAction decorator, to retain the
parse action's name for the trace output.
- Added optional 'fatal' keyword arg to addCondition, to indicate that
a condition failure should halt parsing immediately.
Version 2.1.3 - May, 2016
------------------------------
- _trim_arity fix in 2.1.2 was very version-dependent on Py 3.5.0.
Now works for Python 2.x, 3.3, 3.4, 3.5.0, and 3.5.1 (and hopefully
beyond).
Version 2.1.2 - May, 2016
------------------------------
- Fixed bug in _trim_arity when pyparsing code is included in a
PyInstaller, reported by maluwa.
- Fixed catastrophic regex backtracking in implementation of the
quoted string expressions (dblQuotedString, sglQuotedString, and
quotedString). Reported on the pyparsing wiki by webpentest,
good catch! (Also tuned up some other expressions susceptible to the
same backtracking problem, such as cStyleComment, cppStyleComment,
etc.)
Version 2.1.1 - March, 2016
---------------------------
- Added support for assigning to ParseResults using slices.
- Fixed bug in ParseResults.toDict(), in which dict values were always
converted to dicts, even if they were just unkeyed lists of tokens.
Reported on SO by Gerald Thibault, thanks Gerald!
- Fixed bug in SkipTo when using failOn, reported by robyschek, thanks!
- Fixed bug in Each introduced in 2.1.0, reported by AND patch and
unit test submitted by robyschek, well done!
- Removed use of functools.partial in replaceWith, as this creates
an ambiguous signature for the generated parse action, which fails in
PyPy. Reported by Evan Hubinger, thanks Evan!
- Added default behavior to QuotedString to convert embedded '\t', '\n',
etc. characters to their whitespace counterparts. Found during Q&A
exchange on SO with Maxim.

- do not use results for internal roaming decision
* added a new cred block parameter 'temporary' to allow credential
blocks to be stored separately even if wpa_supplicant configuration
file is used to maintain other network information

Changelog:
2016-07-20 v1.6.0 "Khaki Campbell Duck"
This release improves upon the VP9 encoder and speeds up the encoding and
decoding processes.
- Upgrading:
This release is ABI incompatible with 1.5.0 due to a new 'color_range' enum
in vpx_image and some minor changes to the VP8_COMP structure.
The default key frame interval for VP9 has changed from 128 to 9999.
- Enhancement:
A core focus has been performance for low end Intel processors. SSSE3
instructions such as 'pshufb' have been avoided and instructions have been
reordered to better accommodate the more constrained pipelines.
As a result, devices based on Celeron processors have seen substantial
decoding improvements. From Indian Runner Duck to Javan Whistling Duck,
decoding speed improved between 10 and 30%. Between Javan Whistling Duck
and Khaki Campbell Duck, it improved another 10 to 15%.
While Celeron benefited most, Core-i5 also improved 5% and 10% between the
respective releases.
Realtime performance for WebRTC for both speed and quality has received a
lot of attention.
- Bug Fixes:
A number of fuzzing issues, found variously by Mozilla, Chromium and others,
have been fixed and we strongly recommend updating.
v1.8.2-stable
=============
Bug #3044 - Unable to drag-select in MS Office
Bug #4768 - Copy paste causes 'server is dead' error on switching
Bug #4792 - Server logging crashes when switching with clipboard data
Bug #2975 - Middle click does not close Chrome tab on Mac client
Bug #5087 - Linux client fails to start due to invalid cursor size
Bug #5471 - Serial key textbox on activation screen overflows on Mac
Bug #4836 - Stop button resets to Start when settings dialog canceled
Enhancement #5277 - Auto restart service when synwinhk.dll fails on Windows
Enhancement #4913 - Future-proof GUI login by using newer auth URL
Enhancement #4922 - Add --enable-crypto argument to help text
Enhancement #5299 - High resolution App icon on Mac
Enhancement #4894 - Improve grammar in connection notification dialog
v1.8.0-beta
=============
Enhancement #4696 - Include 'ns' plugin in installers (instead of wizard download)
Enhancement #4715 - Activation dialog which also accepts a serial key
Enhancement #5020 - Recommend using serial key when online activation fails
Enhancement #4893 - Show detailed version info on GUI about screen
Enhancement #4327 - GUI setting to disable drag and drop feature
Enhancement #4793 - Additional logging to output OpenSSL version
Enhancement #4932 - Notify activation system when wizard finishes
Enhancement #4716 - Allow software to be time limited with serial key
* Workaround a 14 year old BSD issue where initial address lifetimes
are transfered to the prefix route and are not updated again,
causing the kernel to remove the route.
The fix is to initially add the address with infinite lifetimes
and then change the lifetimes to the correct ones.
* IPv6 RA routes are now expired by dhcpcd.
* Fix gateway interface assignment on BSD.
* Only mask off signals we do something with
(allows coredumps on some platforms)
* Fix a memory issue where an old lease could be read and discarded
but the buffer length not reset.
* Bind DHCPv6 to the link-local address when not running in master
mode so that many dhcpcd instances can run per interface.
--------------------------
Explicit ChangeLog is not known, but diff shows following lines
+ // Padding size chosen fairly arbitrarily.
+ // Without this padding some systems (e.g. Raspberry Pi 3
+ // wireless interface) failed. dmesg said:
+ // arping: packet size is too short (42 <= 50)
+ const char padding[16] = {0};
-------------------------
adns (1.5.1) UPSTREAM; urgency=medium
* Portability fix for systems where socklen_t is bigger than int.
* Fix for malicious optimisation of memcpy in test suite, which
causes failure with gcc-4.1.9 -O3. See Debian bug #772718.
* Fix TCP async connect handling. The bug is hidden on Linux and on most
systems where the nameserver is on localhost. If it is not hidden,
adns's TCP support is broken unless adns_if_noautosys is used.
* Fix addr queries (including subqueries, ie including deferencing MX
lookups etc.) not to crash when one of the address queries returns
tempfail. Also, do not return a spurious pointer to the application
when one of the address queries returns a permanent error (although,
the application almost certainly won't use this pointer because the
associated count is zero).
* adnsresfilter: Fix addrtextbuf buffer size. This is not actually a
problem in real compiled code but should be corrected.
* Properly include harness.h in adnstest.c in regress/. Suppresses
a couple of compiler warnings (implicit declaration of Texit, etc.)

-Apply patch from Miolaj Kucharski to fix segfault on OpenBSD.
--------------------------
3.10 2016-08-01
- Remove . from @INC when loading optional modules. [Tony Cook, Perl
RT#127834, CVE-2016-1238]
- Removed the default Net::Cmd::timeout() since it inadvertently overrode
the timeout() method in whatever IO::Socket::INET-like class sub-classes
of Net::Cmd also derive from (at least in cases where Net::Cmd takes
precedence in the method resolution, which it should do so that
Net::Cmd::getline() overrides IO::Handle::getline()).
This does cause problems for any Net::Cmd sub-classes that don't provide
(by whatever means) the necessary parts of the interface of
IO::Socket::INET, but since they mostly seem to anyway (apart from the one
that led to the CPAN RT#110978 report!) this is now simply a documented
requirement.
[CPAN RT#116345]
-------------------------------------
1.151940 2015-07-13
- Cache limit increased to 5000 entries
- Instead of a full cache clear, only 1 item is pushed off the end of
the cache when full
- Updated database: Mon Jul 13 06:40:01 2015 UTC.
Update syncthing to v0.14.4

Release Notes for 1.0
Major changes
As a 1.0 release, there are some major changes, many of which are breaking. See also the "backwards compatibility breaks and deprecations" section below.
mpmath is now a hard external dependency for SymPy. sympy.mpmath will no longer work (use import mpmath). See http://docs.sympy.org/latest/install.html#mpmath for more information on how to install mpmath.
The galgebra Geometric Algebra module has been removed. The module is now maintained separately at https://github.com/brombo/galgebra.
The new solveset function is a planned replacement for solve. solve is not yet deprecated, since solveset hasn't yet fully replicated all the functionality of solve. solveset offers an improved interface to solve. See http://docs.sympy.org/latest/modules/solvers/solveset.html for more information on solveset vs. solve.
This will be the last version of SymPy to support Python 2.6 and 3.2. Both of these Python versions have reached end-of-life. Support for other Python versions will continue at least until they have reached end-of-life.
Backwards compatibility breaks and deprecations
In sympy.geometry, Line.equal() has been deprecated in favor of Line.equals().
The dup_inner_subresultants and dmp_inner_subresultants now only return 2 arguments instead of 3. Only those building their own routines from these very low-level functions need to be aware of this.
This release doesn't include copy of the mpmath library, see PR #2192. Please see new installation instructions for SymPy.
The release no longer includes the galgebra subumodule. This module is now maintained separately at https://github.com/brombo/galgebra. See PR #10046.
ClassRegistry is deprecated. It's unlikely that anybody ever used it; it is scheduled for removal for the next version of SymPy after 1.0.
sympy.C is deprecated and scheduled for removal after 1.0, too. For those users who followed some erroneous SymPy documentation and used C as in C.log, just import sympy and use sympy.log instead: this is compatible with SymPy before and after we remove C.
Q.bounded has been deprecated. Use Q.finite instead.
Q.infinity has been deprecated. Use Q.infinite instead.
Q.infinitesimal has been deprecated. Use Q.zero instead.
ask(Q.nonzero(non-real)) now returns False. Note that Q.nonzero is equivalent to ~Q.zero & Q.real. If you intend to find whether x is a non-zero number irrespective of the fact that x is real or not, you should use ask(~Q.zero(x)).
x.is_nonzero now returns True iff x is real and has a non-zero value. If you intend to find whether x is a non-zero number irrespective of the fact that x is real or not, you should use fuzzy_not(x.is_zero).
isprime(Float) now returns False.
ask(Q.integer(Float)) now returns False.
ask(Q.prime(Float)) now returns False.
ask(Q.composite(Float)) now returns False.
ask(Q.even(Float)) now returns False.
ask(Q.odd(Float)) now returns False.
New features
The module sympy.series.ring_series has been updated. New methods for series inversion, expansion of hyperbolic and inverse functions, etc have been added. PR #9262
New module sympy.series.sequences for generating finite/infinite lazily evaluated lists. [PR #9435]
The string representation function srepr() now displays the assumptions used to create a Symbol. For example, srepr(Symbol('x', real=True)) now returns the string "Symbol('x', real=True)" instead of merely "Symbol('x')".
not_empty_in function added to util.py in calculus module which finds the domain for which the FiniteSet is not-empty for a given Union of Sets. [PR #9779]
A new and fast method rs_series has been added for calculating series expansions. It can handle multivariate Puiseux series with symbolic coefficients. It is especially optimized for large series, with speedup over the older series method being in the range 20-1000 times. PR #9775
In [37]: %timeit rs_series(cos(a+b*a**QQ(3,2)), a, 10)
100 loops, best of 3: 5.59 ms per loop
In [38]: %timeit cos(a+b*a**QQ(3,2)).series(a, 0, 10)
1 loops, best of 3: 997 ms per loop
Complex Sets has been added here: sympy.sets.fancysets, use S.Complexes for singleton ComplexRegion class. PR #9463
GeometryEntity now subclasses from sets.Set, so sets.Intersection and sets.Union can be used with GeometryEntitys. For example Intersection(Line((-1,-1),(1,1)), Line((-1,1), (1,-1))) == FiniteSet(Point2D(0,0)).
New module sympy.series.fourier for computing fourier sine/cosine series. [PR #9523]
Linsolve: General Linear System Solver in sympy.solvers.solveset, use linsolve() for solving all types of linear systems. PR #9438
New assumption system is now able to read the assumptions set over Symbol object. For e.g.:
In [7]: x = Symbol('x', positive=True)
In [8]: ask(Q.positive(x))
Out[8]: True
A new handler system has been added as sympy.assumptions.satask which uses satisfiable to answer queries related to assumptions. In case the legacy ask doesn't know the answer, it falls back on satask.
For e.g.
Earlier
>>> ask(Q.zero(x) | Q.zero(y), Q.zero(x*y))
>>> ask(Implies(Q.zero(x), Q.zero(x*y)))
>>> ask(Q.zero(x) | Q.zero(y), Q.nonzero(x*y))
Now
>>> ask(Q.zero(x) | Q.zero(y), Q.zero(x*y))
True
>>> ask(Implies(Q.zero(x), Q.zero(x*y)))
True
>>> ask(Q.zero(x) | Q.zero(y), Q.nonzero(x*y))
False
New module sympy.series.formal for computing formal power series. [PR #9639]
New set class ConditionSet was implemented. [PR #9696]
Differential calculus Methods, like is_increasing, is_monotonic, etc were implemented in sympy.calculus.singularities in [PR #9820]
New module sympy.series.limitseq for finding limits of terms containing sequences. [PR #9836]
New module sympy/polys/subresultants_qq_zz.py :: contains various functions for computing Euclidean, Sturmian and (modified) subresultant polynomial remainder sequences in Q[x] or Z[x]. All methods are based on the recently discovered theorem by Pell and Gordon of 1917 and an extension/generalization of it of 2015. [PR #10374]
Minor changes
limit(sin(x), x, oo) now returns AccumulationBound object instead of un-evaluated sin(oo). Implemented in [PR #10051].
Point is now an n-dimensional point and subclassed to Point2D and Poin3D where appropriate. Point is also now enumerable and can be indexed (e.g., x=Point(1,2,3); x[0])
roots_cubic will no longer raise an error when the sign of certain expressions is unknown. It will return a generally valid solution instead.
Relational.canonical will put a Relational into canonical form which is useful for testing whether two Relationals are trivially the same.
Relational.reversed gives the Relational with lhs and rhs reversed and the symbol updated accordingly (e.g. (x < 1).reversed -> 1 > x
Simplification of Relationals will, if the threshold for simplification is met, also return the Relational in canonical form. One of the criteria of being in canonical form is that the Number will be on the rhs. This makes writing tests a little easier so S(1) > x can be entered as 1 > x or x < 1 (the former being turned into the latter by Python).
boolalg functions And, Or, Implies, Xor, Equivalent are aware of Relational complements and trivial equalities, so, for example, And(x=1) will reduce to False while And(S(1)>x,x<1) reduces to x < 1. This leads to some simplifications in statistical expressions.
Polynomials created using ring now accept negative and fractional exponents. For e.g,
In [1]: R, x, y = ring('x, y', QQ)
In [2]: x**(-2) + y**Rational(2,3)
Out[2]: y**(2/3) + x**(-2)
The function used to test connectivity in Min and Max has been altered to use the weaker form of a relationship since this applies to arguments like floor(x) and x: though, in generally, we cannot say that floor(x) < x, if x is real we do know that floor(x) <= x. This allows Min(x, floor(x)) -> floor(x) without loss of generality when x is real.
Float has changed its default behaviour on string/int/long to use at least 15 digits of precision and to increase the precision automatically. This enables sympify('1.23456789012345678901234567890') to return a high-precision Float. It also means N('1.23456789012345678901234567890', 20) does the right thing (where it previously lost precision because an intermediate calculation had only precision 15). See Issue #8821
The unicode pretty printer now uses a compact single-character square root symbol for simple expressions like sqrt(x) and sqrt(17). You can disable this new behaviour with pprint(sqrt(2), use_unicode_sqrt_char=False).
ask(Q.finite(x), Q.infinite(x)) now returns False.
You can now read the definition of assumption predicates in the docs.
ask(Q.composite(1)) now returns False.
exp(expr) won't simplify automatically based on assumptions on expr. Autosimplification works for numbers and Symbol, though. You'll have to call refine on exp for simplification.
Idx objects can now be summation variables of Sum and Product.
The keyword argument of GramSchmidt was renamed from "orthog" to "orthonormal". This is because GramSchmidt always returns an orthogonal set of vectors but only if that argument is True does it return an orthonormal set of vectors.
RootOf now has a new subclass ComplexRootOf (abbreviated CRootOf). All currently defined functionality is in the subclass. There is a new function rootof with the same call interface as that of RootOf. It will create objects of CRootOf. New code should use rootof instead of RootOf which is planned to become an abstract class.
The vector module has a new function orthogonalize which applies the Gram Schmidt orthogonalization on a sequence of linearly independent vectors and returns a sequence of orthogonal (or orthonormal) vectors. The projection method has been added to compute the vector (or scalar) projection of one vector on another vector. (See https://github.com/sympy/sympy/pull/10474#)

PyTables should be installable very friendly via pip, including NumPy being installed automatically in the unlikely case it is not yet installed in the system. Thanks to Andrea Bedini.
setup.py has been largely simplified and now it requires setuptools. Although we think this is a good step, please keep us informed this is breaking some installation in a very bad manner.
setup.py now is able to used pkg-config, if available, to locate required libraries (hdf5, bzip2, etc.). The use of pkg-config can be controlled via setup.py command line flags or via environment variables. Please refer to the installation guide (in the User Manual) for details. Closes gh-442.
It is now possible to create a new node whose parent is a softlink to another group (see gh-422). Thanks to Alistair Muldal.
link.SoftLink objects no longer need to be explicitly dereferenced. Methods and attributes of the linked object are now automatically accessed when the user acts on a soft-link (see gh-399). Thanks to Alistair Muldal.
Now ptrepack recognizes hardlinks and replicates them in the output (repacked) file. This saves disk space and makes repacked files more conformal to the original one. Closes gh-380.
New pttree script for printing HDF5 file contents as a pretty ASCII tree (closes gh-400). Thanks to Alistair Muldal.
The internal Blosc library has been downgraded to version 1.4.4. This is in order to still allow using multiple threads inside Blosc, even on multithreaded applications (see gh-411, gh-412, gh-437 and gh-448).
The print_versions() function now also reports the version of compression libraries used by Blosc.
Now the setup.py tries to use the ‘-march=native’ C flag by default. In falls back on ‘-msse2’ if ‘-march=native’ is not supported by the compiler. Closes gh-379.
Fixed a spurious unicode comparison warning (closes gh-372 and gh-373).
Improved handling of empty string attributes. In previous versions of PyTables empty string were stored as scalar HDF5 attributes having size 1 and value ‘0’ (an empty null terminated string). Now empty string are stored as HDF5 attributes having zero size
Added a new cookbook recipe and a couple of examples for simple threading with PyTables.
The redundant utilsextension.get_indices() function has been eliminated (replaced by slice.indices()). Closes gh-195.
Allow negative indices in point selection (closes gh-360)
Index wasn’t being used if it claimed there were no results. Closes gh-351 (see also gh-353)
Atoms and Col types are no longer generated dynamically so now it is easier for IDEs and static analysis tool to handle them (closes gh-345)
The keysort functions in idx-opt.c have been cythonised using fused types. The perfomance is mostly unchanged, but the code is much more simpler now. Thanks to Andrea Bedini.
Small unit tests re-factoring:
print_versions() and tests.common.print_heavy() functions
moved to the tests.common module
always use print_versions() when test modules are called as scripts
use the unittest2 package in Python 2.6.x
removed internal machinery used to replicate unittest2 features
always use tests.common.PyTablesTestCase as base class for all test cases
code of the old tasts.common.cleanup() function has been moved to tests.common.PyTablesTestCase.tearDown() method
new implementation of tests.common.PyTablesTestCase.assertWarns() compatible with the one provided by the standard unittest module in Python >= 3.2
use tests.common.PyTablesTestCase.assertWarns() as context manager when appropriate
use the unittest.skipIf() decorator when appropriate
new :class:tests.comon.TestFileMixin: class
Bugs fixed
Fixed compatibility problems with numpy 1.9 and 1.10-dev (closes gh-362 and gh-366)
Fixed compatibility with Cython >= 0.20 (closes gh-386 and gh-387)
Fixed support for unicode node names in LRU cache (only Python 2 was affected). Closes gh-367 and gh-369.
Fixed support for unicode node titles (only Python 2 was affected). Closes gh-370 and gh-374.
Fixed a bug that caused the silent truncation of unicode attributes containing the ‘0’ character. Closes gh-371.
Fixed descr_from_dtype() to work as expected with complex types. Closes gh-381.
Fixed the tests.test_basics.ThreadingTestCase test case. Closes gh-359.
Fix incomplete results when performing the same query twice and exhausting the second iterator before the first. The first one writes incomplete results to seqcache (gh-353)
Fix false results potentially going to seqcache if tableextension.Row.update() is used during iteration (see gh-353)
Fix Column.create_csindex() when there’s NaNs
Fixed handling of unicode file names on windows (closes gh-389)
No longer not modify sys.argv at import time (closes gh-405)
Fixed a performance issue on NFS (closes gh-402)
Fixed a nasty problem affecting results of indexed queries. Closes gh-319 and probably gh-419 too.
Fixed another problem affecting results of indexed queries too. Closes gh-441.
Replaced “len(xrange(start, stop, step))” -> “len(xrange(0, stop - start, step))” to fix issues with large row counts with Python 2.x. Fixes#447.
Other changes
Cython is not a hard dependency anymore (although developers will need it so as to generated the C extension code).
The number of threads used by default for numexpr and Blosc operation that was set to the number of available cores have been reduced to 2. This is a much more reasonable setting for not creating too much overhead.
