New items in core:
function powerseries: power series for function lambert_w (thanks to Dimiter Prodanov)
init option strips any directories and the last extension from the given value. This value is used as the basename instead of "maxima-init" for the name of the init file. This is an incompatible change.
init-mac and --init-lisp are now (deprecated) aliases for --preload.
This is an incompatible change.
The variable $maxima_frontend_bugreportinfo allows the frontend to tell bug_report() how to report frontend bugs.
New items in share:
package pslq: PSLQ algorithm for finding integer relations among inexact numbers (thanks to Andrej Vodopivec)
package nelder_mead: Nelder-Mead algorithm for minimization without derivatives (thanks to Mario S. Mommer and Andrej Vodopivec)
package decfp: exact decimal floats (thanks to Richard J. Fateman)
Changes in core:
Maxima/ABCL: Use the option --noinform for ABCL. This suppresses the startup messages from ABCL, so that e.g. the Maxima
option --quiet is quiet.
Fix command line options for Maxima with ABCL.
Functions that return lambda expressions with free variables are now translated correctly. Previously many of these lambda expressions would cause internal errors when called.
Array functions and subscripted functions can now be translated.
Previously these would fail to translate with no explanation. configure: If the user doesn't specify a specific lisp maxima is compiled with all suitable lisp compilers.
no-init now actually inhibits load if the user init files.
Init files that are loaded are now printed on startup
Add functions and variables for inspecting floating point properties
Variables: most_positive_float, most_negative_float, least_positive_float, least_positive_normalized_float, least_negative_float
Functions: float_eps, bitfloat_eps, float_precision, unit_in_last_place, is_power_of_two, scale_float, decode_float, integer_decode_float
Simplify elliptic_kc((sqrt(3)+2)/4)
Fix bug in converting inverse_jacobi_ds to elliptic_f.
bfallroots with integer coefficients was not returning roots with the specified precision.
Add hypergeometric representations for elliptic_ec, elliptic_kc, expintegral_chi, expintegral_ci, expintegral_shi, expintegral_si, expintegral_li, expintegral_ei, expintegral_e
hgfred can simplify some 2F2 functions to expintegral_ci.
hgfred can simplify some 1F2 functions to expintegral_si.
Reject invalid values for debugmode.
disp_time variable removed because it was undocumented and didn't actually do anything.
Floats are displayed readably by default (fpprintprec = 0)
Function texput: punt to previously defined TeX output function
when false is returned
Strings are comparable under "<", "<=", ">=", ">"
Function plot2d: new option gnuplot_svg_background
Changes in share:
package contrib_ode: Fix name of Clairaut differential equation
in code and documentation. Was misspelled as Clairault.

decomposition, for time and memory assessments
package namespaces: expunge this package, moved to Github
package ezunits: derive units for diff, integrate, and 'at'

Document harmonic_number and harmonic_to_psi functions from simplify_sum.
package draw: allow points(...) to contain nonnumeric (including non-finite floats) data
package draw: honor fill_density in errors, polygon, ellipse, bars, explicit, and region
package descriptive: implementation of skyline (outline) histogram
package descriptive: optional weight argument recognized by mean, var, std, and other functions
package distrib: maximum likelihood estimators (mle_something) for several distributions
package graphs: new functions get_unique_vertex_by_label and get_all_vertices_by_label
Changes in Xmaxima:
Changes in the Windows installer:
Update Gnuplot, SBCL, wxWidgets and TCL/TK.
Compile a recent texinfo for building the installer. Maxima now needs
texinfo 6.8, but 6.7 is included in the usual build machines for
nightly builds, etc.

commit fe1d8cf: avoid clobbering global state when autoloading
commit 70a5f78: expunge calls to 'sign' in share package distrib
commit 7bc968a: in printf, be more consistent about non-numeric argument for ~e, ~f, and ~g
Documentation:
Help can use html docs instead of displaying help to the terminal.
This is enabled by setting output_format_for_help to 'html; it defaults
to 'text. Use 'frontend to display help using Xmaxima, wxMaxima or
other frontends.
Add documentation for trigtools to the manual.
Some reordering of the trig functions in the manual.
Some renaming of sections in the manual to be more explicit.
Add more cross references.
Add more examples for erf_representation, hypergeometric_representation, expintrep, expintexpand, besselexpand
Add examples for the ggf package.
