SciPy 0.17.0 is the culmination of 6 months of hard work. It contains many
new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes in
this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Moreover, our development attention will now shift to
bug-fix releases on the 0.17.x branch, and on adding new features on the
master branch.
This release requires Python 2.6, 2.7 or 3.2-3.5 and NumPy 1.6.2 or greater.
Release highlights:
* New functions for linear and nonlinear least squares optimization with
constraints: scipy.optimize.lsq_linear and scipy.optimize.least_squares
* Support for fitting with bounds in scipy.optimize.curve_fit.
* Significant improvements to scipy.stats, providing many functions with
better handing of inputs which have NaNs or are empty, improved
documentation, and consistent behavior between scipy.stats and
scipy.stats.mstats.
* Significant performance improvements and new functionality in
scipy.spatial.cKDTree.
SciPy 0.16.0 is the culmination of 7 months of hard work.
Highlights of this release include:
* A Cython API for BLAS/LAPACK in scipy.linalg
* A new benchmark suite. It’s now straightforward to add new benchmarks,
and they’re routinely included with performance enhancement PRs.
* Support for the second order sections (SOS) format in scipy.signal.

original implementations of various other algorithms.
3.2.4
NEW FEATURES
install.packages() and related functions now give a more informative
warning when an attempt is made to install a base package.
summary(x) now prints with less rounding when x contains infinite values.
provideDimnames() gets an optional unique argument.
shQuote() gains type = "cmd2" for quoting in cmd.exe in Windows.
The data.frame method of rbind() gains an optional argument stringsAsFactors
(instead of only depending on getOption("stringsAsFactors")).
smooth(x, *) now also works for long vectors.
tools::texi2dvi() has a workaround for problems with the texi2dvi script
supplied by texinfo 6.1.
It extracts more error messages from the LaTeX logs when in emulation mode.
DEPRECATED AND DEFUNCT
Use of SUPPORT_OPENMP from header ‘Rconfig.h’ is deprecated in favour of
the standard OpenMP define _OPENMP.
(This has been the recommendation in the manual for a while now.)
The make macro AWK which is long unused by R itself but recorded in file
‘etc/Makeconf’ is deprecated and will be removed in R 3.3.0.
The C header file ‘S.h’ is no longer documented: its use should be
replaced by ‘R.h’.
3.2.3
NEW FEATURES
Some recently-added Windows time zone names have been added to the
conversion table used to convert these to Olson names. (Including
those relating to changes for Russia in Oct 2014, as in PR#16503.)
(Windows) Compatibility information has been added to the manifests
for ‘Rgui.exe’, ‘Rterm.exe’ and ‘Rscript.exe’. This should allow
win.version() and Sys.info() to report the actual Windows version up
to Windows 10.
Windows "wininet" FTP first tries EPSV / PASV mode rather than only
using active mode (reported by Dan Tenenbaum).
which.min(x) and which.max(x) may be much faster for logical and integer
x and now also work for long vectors.
The ‘emulation’ part of tools::texi2dvi() has been somewhat enhanced,
including supporting quiet = TRUE. It can be selected by texi2dvi =
"emulation".
(Windows) MiKTeX removed its texi2dvi.exe command in Sept 2015:
tools::texi2dvi() tries texify.exe if it is not found.
(Windows only) Shortcuts for printing and saving have been added to
menus in Rgui.exe.
loess(..., iterTrace=TRUE) now provides diagnostics for robustness
iterations, and the print() method for summary(<loess>) shows slightly
more.
The included version of PCRE has been updated to 8.38, a bug-fix release.
View() now displays nested data frames in a more friendly way.
Upstream changes:
Changes in version 1.0-5 (2016-02-02)
o improvements in quantile estimation
Changes in version 1.0-4 (2016-01-19)
o a new algorithm for quantile estimation, again. Quantiles are
now computed by a stochastic root finding algorithm. Note
that f.quantile in the output of qmv{t,norm} is now (again)
the squared difference between the cdf evaluated at the
quantile and the level. The \code{interval} argument to the
quantile functions is used as a starting value for the
root finder when available.
o clean-ups in C and R code and documentation
Changes in version 1.0-3 (2015-07-21)
o new algorithm for quantile estimation. Quantiles are
now computed by minimising the squared distance between the
distribution function and the probability whereas previous versions
used uniroot(). The procedure is now performed multiple times with
difference random seeds in order to stabilise the results. The
\code{interval} argument to the quantile functions is IGNORED now.
Upstream changes:

Some improvements were made in the primal and dual simplex
solvers to make the solution process more numerically stable.
An experimental long-step ratio test feature was added to the
dual simplex. On API level this feature is available thru the
GLP_RT_FLIP option. For glpsol it is available thru the options
--flip (for MIP) or --flip and --dual (for LP). This feature is
not documented yet.
Additional check was added to reject wrong solutions sometimes
reported by the PROXY heuristic.
A bug (memory leak) was fixed in the FPUMP heuristic routine.
The header sql.h was renamed to avoid conflicts with standard
ODBC headers.

CORRECTIONS TO DATA
o Data in the dataset mendelABC was in error. Substantial corrections
have been made. (Thanks to Boris Igic for drawing the errrors to
our attention.)
Upstream changes:
2 February 2016: statmod 1.4.24
- speedup for rinvgauss() by replacing rchisq() with rnorm() and
rbinom() with runif().
- speedup for qinvgauss() by using qgamma as starting approximation
for very small right tail probabilities, and inverse chisq as
starting approximation for very small left tail probabilities.
- qinvgauss() now computes Newton step using log probabilities
and a Taylor series expansion for small steps. This improves
accuracy in extreme cases. The stopping criterion for the Newton
iteration has been revised.
- Bug fix to dinvgauss(), pinvgauss() and qinvgauss() which were not
preserving attributes of the first argument.
30 December 2015: statmod 1.4.23
- qinvgauss() has been improved to return best achievable machine
accuracy. It now checks for backtracking of the Newton iteration.
- dinvgauss() and pinvgauss() now check for a wider range of special
cases. This allows them to give valid results in some cases
for infinite or missing parameter values and for x outside the
support of the distribution.
26 October 2015: statmod 1.4.22
- Functions needed from the stats and graphics packages are now
explicitly imported into the package NAMESPACE.
Upstream changes:
3.0612 2016-01-09
- Move the VCS repository to GitHub.
- People are more used to it, and it can take part in the CPAN pull-req
challenge.

- https://rt.cpan.org/Ticket/Display.html?id=110987
- Thanks to Salvatore Bonaccorso for the report and patch.
3.0610 2016-01-06
- Clarified the docs for add_data_with_samples().
- Some people thought they were repeat counts of the data , but they
are normally ignored.
- Replace remaining tabs with spaces.
3.0609 2015-06-19
- Update some old URLs and addresses.

Changes:
- New package implementing van Hoej factorization algorithm
for LODO-s.
- Gcd over Expression(Integer) now uses modular method.
- Improvements to integrator, in partucular trigonomoetric
functions are consistently integrated via transformation
to complex exponentials.
- Some categories and domains are more general. In particular
OrderedFreeMonoid is removed, as ordered case is handled
by FreeMonoid.
- Category Monad in renamed to Magma. Domain Magma is
renamed to FreeMagma.
Bug fixes, in particular:
- Coercion of square matrices to polynomials is fixed.
- Problem with division by 0 in derivative of 'ellipticPi'
is fixed.
- Division in Ore algebras used to cause infinite loop
when coefficients were power series.

PARI-GP is a package which is aimed at efficient computations in
number theory, but also contains a large number of other useful
functions. It is somewhat related to a Computer Algebra System, but
is not really one since it treats symbolic expressions as mathematical
entities such as matrices, polynomials, series, etc..., and not as
expressions per se. However it is often much faster than other CAS,
and contains a large number of specific functions not found elsewhere,
essentially for use in number theory.
This package can be used in an interactive shell (GP) or as a C/C++
library (PARI). It is free software, in the sense of freedom AND 'free
of charge'.
This is the old 2.3 version of pari.
