# Seer Change Log

## [2.5beta] - 2024-XX-XX
* Starting the 2.5 development cycle.

## [2.4] - 2024-03-18
* Changed main icon to a more license friendly one.
  All icons are now GPLv3, CC3.0, or CC4.0
* Fixed string compares for breakpoint conditions (#184)
* Added '--bs' command line option to specify a breakpoint at a source.cpp:lineno
* Fixed long tooltips text by restricting them to 100 characters. (#189)
  The text in the various viewing dialogs is still the full length.
  The 100 limit probably needs to be configurable.
* Added register profiles to show only interesting/relevant registers.
* Added UTF-8,16,32 support in the Memory Visualizer.
* Added an internal "dark" and "light" theme via the View->Style menu.
* Added option to open the current source file in an external editor.
* Fixed saving of RR parameters in config dialog.
* Sped up some visualization views.

## [2.3] - 2023-11-19
* In the margins of the source windows, allow CTRL+DoubleClick to do a quick RunToLine or RunToAddress.
* Add --gdb-program and --gdb-arguments to command line to override settings from Seer's config.
* Fixed a rare bug with blank lines from gdb causing a segv in GdbMonitor.
* Fixed bug specifying path to "rr" debugger.
* Add option to reload source file if it changes.
* Tighten up the layout by removing some needless whitespace.
* Move gdb messages to a tab in the breakpoints window.
    - Options to raise on every message, never, or important messages.
* Add C++ level (11 or 17) depending on qt5 or qt6 compile.
* Fixed up column resizing for the Variable logger (#173)
* Use monspace font, where it makes sense (#175)
* Allow copy to clipboard (#176)
* Fixed hovering a variable name and value (#179)
* Add nested struct viewing in "locals", "arguments", "logger", and "tracker" tabs. (#180)

## [2.2] - 2023-09-07
* Fixed infinite loop when starting with RR mode.
* Reworked RR mode to directly run 'rr replay'.
  No need to start a 'rr server' and connect to it.
  https://github.com/epasveer/seer/wiki/RR-and-Seer
* Fixed Source handling in source browser. Qt5 mode was broken.
  Qt6 works.  Directory paths need a tailing "/*"

## [2.1] - 2023-08-23
* Add Execution dialog to record breakpoint events. This solves the problem
  of too many break/error dialogs to "swat away" as the program is debugged.
* Add a method to add/change gdb commands to execute when a breakpoint (breakpoint, watchpoint, catchpoint) is reached.
* Add a method to add/change a breakpoint's condition command.
* Add a method to add/change a breakpoint's ignore count.
* Add a method to add/change a breakpoint's command list.
* Debug dialog for "attach" mode now detects executable name and path from /proc/<pid>/exe.
* Commandline for "attach" mode now detects executable name and path from /proc/<pid>/exe.

## [2.0] - 2023-03-06
* Seer is Qt6 based. Still compiles with Qt5.
* See Seer's Wiki page for compile instructions.
     https://github.com/epasveer/seer/wiki

## [1.17] - 2023-04-23
* Add support for the RR debugger.
  https://github.com/epasveer/seer/wiki/RR-and-Seer
* Add a dialog when a breakpoint is reached.

## [1.16] - 2023-04-07
* Add pid to main window and console title bars.
* The Pending flag is automatically supplied to the breakpoint function in
  the Debug dialog for the Run mode. Some apps use deferred loading of code
  with dlopen().
* Fixed bug when restoring from project file with 'start' mode.
* ADA: Improve visualizers for Ada arrays. "(system.address) 0x7fffffffcf10"
* ADA: Add Ada task browser.
* ADA: Add Ada specific catchpoints.
* ADA: Add Ada exception brower.
* Add a Shortcut (CTRL-I) to interrupt the running program.

## [1.15] - 2023-03-04
* Revamp Debug dialog. Move debug modes into "tabs".
* Add "help" icon to each debug mode in Debug dialog.
* Add 'pre' and 'post' gdb commands that can be executed
  just before and just after the program is loaded into gdb.
* Add the concept of 'project' files that can be created and loaded.
  Project files contain all settings available in the Debug dialog.
* Assembly view can now be shown in 2 modes. See "Settings->Configure->Assembly"
     - Function. The view shows all assembly in the function 
       the $PC is in.
     - Length. The view shows N bytes of assembly after the $PC. Used
       for code that is pure assembly or has no debug information.
* Minor fixes when debugging corefiles.
* Fixed breakpoints with conditional statements.
* Fixed up icons and Debian "copyright" file for Debian Intent-To-Package.
* Double-clicking on a breakpoint in the source window will delete it.
  Previously it would disable it.
* Assembly Tab - show only Nexti and Stepi buttons.
  Source tabs - show only Next and Step buttons.
* Hide certains buttons (Run, Start, ...) depending on Debug mode (run, attach,
  connect, etc...)
* Save state of tabs (tab order and current tab). So next session will get them.

## [1.14] - 2023-01-02
* Happy New Year!
* Add 'tabsize' property to Source Editors to properly display source files
  containing tab characters. Default is 4. Can be changed by the Editor config
  page.
