GlobalSettings: Implement undo function for the "cancel" button

[pulseview.git] / NEWS

0.3.0 (2016-01-29)
------------------

 * PulseView now uses libsigrokcxx (the libsigrok C++ bindings library).
 * Update to use the new APIs of libsigrokcxx 0.4.x and libsigrokdecode 0.4.x.
 * Add support for vertical scaling of analog and logic traces.
 * Add a "Save selection range as..." feature. This allows the user to select
   a subset of the data (using the cursors) and save that into a file in the
   libsigrok session format (*.sr).
 * Remember the directory of the last file that was opened/saved.
 * Automatically save and restore (upon PulseView shutdown/startup):
    - the window state (size, position)
    - the most recently used device
 * Implement pinch-zoom support (useful e.g. on tablets).
 * Implement an "always zoom-to-fit" feature.
 * Implement a "sticky scrolling" feature, using hotkey 's' (bug #121).
 * Show icons for active triggers on the right-hand side of the window.
 * Cursors: Also show the frequency in addition to distance/time (bug #502).
 * List available serial ports (for serial-based devices) in a drop-down.
 * Add support for trace groups. An arbitrary number of traces can be grouped
   together, which allows for dragging them around as a group and re-ordering
   traces within the group. Hotkeys: group (CTRL+g), ungroup (CTRL+u).
 * Use either alternating gray values as trace background color, or the
   trace's own color (slightly modified). This behaviour is configurable
   via the menu or the 'b' hotkey.
 * Show a vertical marker at the trigger point (bug #685).
 * Sampling bar: Show the total sampling time in a tooltip.
 * Trace/Decoder popups: Close the popup when the ENTER/RETURN key is pressed.
 * Improve horizontal arrow-key scrolling step size.
 * The viewport can now be dragged vertically as well.
 * Add support for placing arbitrary markers (double-click at the desired
   position in the ruler area) with arbitrary name/content. Markers can be
   removed via the delete key (or the right-click context menu).
 * Show full device names in the device drop-down.
 * The device selector combobox is now a split button. Clicking on a device
   name will open the "Connect to Device" dialog which allows for manual
   device selection. Clicking on the small arrow will open a drop-down with
   all autodetected devices.
 * The main menu is now hidden by default, pressing ALT will make it appear,
   pressing ALT or ESC will hide it again.
 * Add an Export menu item, which can export the data in various formats.
 * Add an Import menu item, which allows data import of various formats.
 * Support specifying input files + formats on the command-line (-i and -I).
 * Update the possible samplerates/samplecounts widgets when needed.
 * Various UI fixes and improvements (colors, font sizes, clipping, etc).
 * Add support for the SR_CONF_{POWER_OFF,PROBE_FACTOR} config keys.
 * Include the device / filename in the window title (bug #244).
 * Keyboard shortcuts:
   - Add space as a shortcut to start/stop an acquisition.
   - Add shortcuts for the open/save menu items (CTRL-o, CTRL-s).
   - Add trace group shortcuts: group (CTRL+g), ungroup (CTRL+u).
   - Add 's' as shortcut for enabling/disabling sticky scrolling.
   - Add 'b' as shortcut for colored / alternating-gray trace backgrounds.
 * Add a few missing toolbar buttons.
 * Provide tooltips for decoder annotations (which show the "full" annotation
   text regardless of zoom-level).
 * Improvements to work (better) with Qt5 (Qt4 remains supported as well).
 * The whole code-base has been converted to C++11 (dropping the use
   of various Boost functionality in favor of std:: equivalents).
 * Build system:
   - Always build with -std=c++11.
   - Auto-detect Qt4 or Qt5. If both are available, Qt5 will be selected
     unless the cmake option FORCE_QT4 is set to TRUE.
   - Don't use Qt-defined keywords (can cause issues with other headers).
   - Fix an issue with QtSvg linking (bug #369).

 * Almost all operations in PulseView work in an "auto-apply" style, i.e.
   any changes in the GUI popups (decoder channel assignment, decoder option
   changes, device channel changes, device option changes, and so on) have an
   immediate effect (you don't have to click on any "OK" buttons).
