5 ## Version 15 (2021-02-25)
7 **Important change:** `jack_mixer` now uses [meson] for building and
8 installation. See [INSTALL.md] for new build instructions.
13 * A global setting for default project file path was added and can be changed
14 in the preference dialog.
16 The default value is `$XDG_DATA_HOME/jack_mixer` (which is normally
17 `~/.local/share/jack_mixer`).
19 * A "Recent projects" menu was added, to allow loading recently used / saved
20 projects more quickly.
22 * Direct channel output ports are now optional and can be enabled/disabled in
23 the channel preferences dialog.
25 * Ctrl+left-click on the mute ("M") or solo ("S") channel buttons now activates
26 exclusive mute resp. solo.
28 * A man page for `jack_mixer` was added.
30 * `jack_mix_box`now supports the `-p|--pickup` command line option to enable
31 MIDI pickup mode, to prevent sudden volume or balance value jumps.
36 * Activating the solo function on an input channel could cause its
37 output signal be sent to the monitor outputs instead of the signal
38 from the channel, which had monitoring activated.
40 * Volume and balance level and mute and solo state changes originating from
41 the UI now send the correct assigned MIDI CCs, allowing for MIDI feedback
42 to controllers. Same for changes originating from reception of assigend MIDI
45 * The handler for right-clicking the input channel mute/solo buttons, was
46 accidentally removed and is now re-instated.
48 * Creating a new output channel assigns it a randomly chosen color,
49 which can be changed in the new channel dialog (used to work
50 some releases ago, but was broken at some point).
52 * The `jack_mix_box` command line options `--help` and `--stereo`
53 erroneously required an argument.
55 * Saving the current project on reception of the `SIGUSR1` signal, which is a
56 requirement for LADISH level L1 support, was broken in version 14.
58 * When re-ording channels via drag-and-drop, the order of the edit / remove
59 channel menu items were not updated.
61 * When creating an output channel, it could happen that the initial channel
62 volume would ranmdomly be set to -inf or 0 dB, regardless of what was
63 selected in new channel dialog.
68 * The minimum supported Python version is now 3.6.
70 * The `jack_mix_box` command line usage help message was improved.
72 * The channel strip buttons (solo, mute, etc.) now have more distinctive colors
73 when activated or the mouse hovers over them
75 * The balance slider step size was increased slightly so right-clicking the
76 slider changes the value more rapidly.
78 * When using the "Save as..." function, `jack_mixer` now sets the default
79 filename and directory for file chooser to the last ones used.
81 * A window title was added to the preferences dialog.
83 * MIDI control for mute and solo now interprets control value 0-63 as off
84 and 64-127 as on, instead of toggling the state on reception of any
88 Project infrastructure and internals:
90 * The `jack_mixer_c` Python extension module, which was originally implemented
91 in hand-written C code using the PYTHON C API, was replaced with the
92 `_jack_mixer` extension module implemented in [Cython], which generates the C
93 code in `_jack_mixer.c`.
95 * The autotools build toolchain was replaced with a build setup using [meson],
96 which improves build times and maintainability markedly. See the file
97 [INSTALL.md] for updated build and installation instructions.
99 * A build option to allow buidling only `jack_mix_box` was added (`-Dgui=disabled`).
101 * All Python code was re-formatted with [black].
103 * All errors and warings reported by [flake8] were fixed or are expressivley and
106 * The file `version.py` is now generated from the version set in the project
107 definition in the top-level `meson.build` file, leaving this as the only
108 place where the version number needs to be updated before a release.
110 * The `NEWS` file was renamed to `CHANGELOG.md` and converted to Markdown

121 ## Version 14 (2020-10-15)
123 * Changes to channel fader/meter layout and features:
124 * Added K20 and K14 scales.
125 * Added tick marks for left/center/right on balance slider and add tooltip
126 displaying left/right value.
127 * Added maximum width for control group labels. Labels are ellipsized if
128 too long and a tooltip with the full name is added.
129 * Channel add/property dialogs usability improvements:
130 * Remember last used settings for new input/outut channel dialogs (MIDI CCs
131 are always initialized with -1 by default, so they can be auto-assigned).
132 * Channel name is pre-filled in with "Input" or "output" and an
133 auto-incremented number suffix.
134 * Add mnemonics for all input/output channel dialog fields.
135 * When running under NSM, closing the main window only hides UI and the "Quit"
136 menu entry is replaced with a "Hide" entry.
137 * Added a global option to always ask for confirmation when quitting
139 * Allow drag'n'drop to change channel positions.
140 * Added ability to shrink/expand width of input and output channels.
141 * The font color of control group labels automatically adapts to their
142 background color for better contrast and readability.
143 * Fixed: Ctrl-click on volume fader sets it to 0.0 dbFS, not 1.0.
144 * Fixed: some issues with channel monitoring.
145 * Fixed: don't create empty project file on new NSM session.
146 * Fixed: on project load, give input focus to fader of last added channel and
147 deselect volume entry widget so keyboard input doesn't accidentally change
