12 {% include release_news_select.md %}
13
14 <pre>
15 ** A graphical Variable Editor has been added to the GUI interface.
16 It uses a spreadsheet-like interface for quick, intuitive editing
17 of variables. The Variable Editor is launched by double-clicking
18 on a variable name in the Workspace Window or by typing
19 "openvar VARIABLE_NAME" in the Command Window.
20
21 ** On systems with 64-bit pointers, --enable-64 is now the default and
22 Octave always uses 64-bit indexing. However, if the configure
23 script determines that the BLAS library uses 32-bit integers, then
24 operations using the following libraries are limited to arrays with
25 dimensions that are smaller than 2^31 elements:
26
27 BLAS LAPACK QRUPDATE SuiteSparse ARPACK
28
29 Additionally, the following libraries use "int" internally, so
30 maximum problem sizes are always limited:
31
32 glpk Qhull
33
34 ** The octave command no longer starts the GUI by default. Most users
35 starting Octave from a shell were expecting the command line
36 interface, and desktop launchers already required the `--force-gui'
37 option. With this change, desktop launchers should be modified to
38 use the new option `--gui'. The previous `--force-gui' option will
39 continue to work, and maps to `--gui', but it will be removed in
40 Octave 6.
41
42 ** A known bug in Qt (https://bugreports.qt.io/browse/QTBUG-55357) is
43 addressed by limiting GUI sub-panel relocation capabilities for Qt
44 versions in the range >= 5.6.1 and < 5.7.1. However, this may not
45 thoroughly avoid issues on all platforms.
46
47 ** A new container data type--containers.Map--is available. Map is a
48 key/value storage container (a.k.a, a hash) that efficiently allows
49 storing and retrieving values by name, rather than by position which
50 is how arrays work.
51
52 ** The bareword "import" is now recognized in scripts and functions.
53 However, the functionality to import functions and classes from
54 other namespaces into the local scope has not yet been implemented.
55 Attempting to use "import" will provoke an error message.
56
57 ** hex2num and num2hex now work for integer and char types and num2hex
58 may optionally return a cell array of strings instead of a character
59 array. If given a cell array of strings, hex2num now returns a
60 numeric array of the same size as the input cell array. Previously,
61 hex2num would accept a cell array of strings of arbitrary dimension
62 but would always return a column vector.
63
64 ** New special functions cosint, sinint, and gammaincinv have been added.
65
66 ** Special functions in Octave have been rewritten for larger input
67 domains, better accuracy, and additional options.
68 * gammainc now accepts negative real values for X.
69 * improved accuracy for gammainc, betainc, betaincinv, expint.
70 * gammainc has new options "scaledlower" and "scaledupper".
71 * betainc, betaincinv have new option "upper".
72
73 ** The "names" option used in regular expressions now returns a struct
74 array, rather than a struct with a cell array for each field. This
75 change was made for Matlab compatibility.
76
77 ** The quadcc function now uses both absolute tolerance and relative
78 tolerance to determine the stopping criteria for an integration.
79 To be compatible with other quadXXX functions, such as quadgk, the
80 calling syntax has changed to
81
82 quadcc (f, a, b, [AbsTol, [RelTol]])
83
84 To update existing code, change instances of RelTol to [0, RelTol].
85
86 quadcc (f, a, b, tol) => quadcc (f, a, b, [0, tol])
87
88 A warning that a single tolerance input is now interpreted as an
89 absolute tolerance will be issued in Octave versions 4.4 and 5,
90 after which it will be removed. The warning has ID
91 "Octave:quadcc:RelTol-conversion" and can be disabled with
92
93 warning ("off", "Octave:quadcc:RelTol-conversion")
94
95 ** The qr function now returns a standard factorization unless
96 explicitly instructed to perform an economy factorization by using a
97 final argument of 0.
98
99 ** The Qt graphics toolkit now supports offscreen printing without osmesa
100 if Octave was built with Qt >= 5.1.
101
102 ** The built-in pager for display of large data is now disabled by
103 default. To re-enable it for every Octave session add the following
104 to your .octaverc file:
105
106 more on;
107
108 ** The FLTK toolkit is no longer prioritized for development. The
109 number of Octave Maintainers is too small to support three different
110 graphic toolkits. New development will target the Qt toolkit.
111 While no longer prioritized, the FLTK toolkit is not deprecated and
112 there is no schedule for its removal.
113
114 ** The graphic object property "PickableParts" has been implemented
115 which controls whether an object can accept mouse clicks.
116
117 ** The graphic object property "Interruptible" has been fully
118 implemented which controls whether a running callback function can
119 be interrupted by another callback function.
120
121 ** The graphic object property "HitTest" has been updated to be fully
122 compatible with Matlab.
123
124 ** Text objects now implement the properties "BackgroundColor",
125 "EdgeColor", "LineStyle", "LineWidth", and "Margin".
126
127 ** An initial implementation of alpha transparency has been made for
128 patch and surface objects. Printing to svg and pdf is supported.
129
130 ** ishandle now returns true for both graphics handle objects and
131 Java objects. The latter change was made for Matlab compatibility.
132 Use ishghandle or isgraphics if it is important not to include Java
133 objects.
134
135 ** The pkg command now accepts a URL as an argument, allowing a valid
136 Octave package to be installed from any remote host with one command,
137 for example
138
139 pkg install https://example.org/download/example-package.tar.gz
140
141 ** The following statistical functions have been moved from core
142 Octave to the statistics package available from Octave Forge.

387
388 ** The header file oct-alloc.h has been removed along with the macros
389 that it defined (DECLARE_OCTAVE_ALLOCATOR, DEFINE_OCTAVE_ALLOCATOR,
390 and DEFINE_OCTAVE_ALLOCATOR2).
