[pulseview.git] / NEWS

0.4.0 (2017-06-12)
------------------

 * Updated build requirements:
   - A C++ compiler with full C++11 support (g++ >= 4.8.1 or clang++ >= 3.3)
   - cmake >= 2.8.12
   - libglib >= 2.28.0
   - glibmm-2.4 >= 2.28.0
   - Boost >= 1.55:
     - New requirement: libboost-serialization.
     - Dropped requirement: libboost-thread.
   - libsigrokcxx >= 0.5.0 (libsigrok C++ bindings)
   - libsigrokdecode >= 0.5.0
   - Dropped support for Qt4; PulseView now requires Qt5.
 * Add the concepts of sessions and views to PulseView: 
   - Sessions represent individual files/device instances.
     Each session is represented as a tab in PulseView.
   - Views are different data representations of one specific session.
     For example, different views of a session can have different zoom levels,
     can be scrolled to different positions, etc. etc.
     Each view is a dock window within the respective session's tab.
   - The view docks can be repositioned, resized and extracted out into their
     own individual windows.
   - Sessions and views are partially saved and restored when PulseView
     exits/starts. Not all information is restored yet, though (e.g. decoders).
   - Add CTRL-q to close PulseView, CTRL-w to close a session tab (bug #899).
 * Add support for saving analog data to .sr files.
 * Analog signal traces:
   - Add initial implementation of a vertical grid for analog traces.
   - Add a dropdown for the vertical resolution setting.
   - Show the vertical resolution info on the right-hand side of the trace.
   - Make the number of vertical/horizontal divisions configurable.
   - Add an option to enable autoranging for analog channels.

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.
