 # Changelog
 
+## v0.5.0 (11 Jan 2024)
+
+**New**
+
+  * New, reworked application icon.
+  * Graph is now mouse interactive:
+  * You can now drag to move and scroll to zoom!
+  * Builtin functions now provide usage when used in the autocomplete of the expression editor.
+
+**Changes**
+
+  * When creating an object that can be positioned, new default behavior is to pick first instead of opening object settings.
+  * Icons with text now use the SVG's text element, allowing them to integrate better with the system's default font.
+  * Special characters popup is now context aware (e.g. no sub/supscript symbols in expressions).
+  * New symbols in special characters popup.
+  * Integrals and derivatives can now be provided with an executable object (e.g. Functions) instead of strings as function.
+  * New description on Linux.
+
+**Fixed bugs**
+
+  * Fixing ∞ 'variable' in domains and expressions.
+  * Several other bugs related to constants in expresions were fixed as well.
+  * Builtin functions now send an error message when not provided with the proper arguments.
+
+**Internal changes**
+
+  * Updated to PySide6 v6.6.1.
+  * Reworked continuous functions' rendering to make it faster.
+  * Removed old bits from an unfinished new parser that weren't used.
+  
+## v0.4.0 (27 May 2023)
+
+**Changes**
+
+  * Fully ported to PySide6 (Qt6).
+  * Greet screen settings are now scrollable.
+  * Changelog is now freezed to current version.
+
+**New**
+
+  * Customizable color schemes for expressions.
+  * New, rewamped and improved picked location overlay settings:
+  * It's now possible to disable picking x or y when setting a location.
+  * Properties which are related to positioning (X, Y, Label's X position) can now be set using the picker.
+  * Visual redesign that enhances readability of settings.
+  * There is now a button to hide picker settings.
+
+**Fixed bugs**
+
+  * Cursors in expression are now easier to see.
+  * Symbols in LaTeX rendered Texts cause the LaTeX renderer to crash.
+  * Underscores in distribution names are automatically removed if the name is modified.
+  * Autocomplete categories now properly respect theme colors.
+  * Functions in expressions (like indexOf, map...) now properly send errors when the arguments are of the wrong type or count.
+  * Executable Objects called (like functions, bode magnitures, phases...) now send an error if provided with no arguments.
+  * Function calls with no argument no longer make LogarithmPlotter crash under certain circumstances.
+  * Thank you dialog's lists are no longer draggable.
+
+**Internal changes**
+
+  * A lot of inner changes led by porting to Qt6, fixing a lot of bugs at the same time.
+  * Disabled auto detect of visual theme if the `QT_QUICK_CONTROLS_STYLE` environment variable is set.
+  * (macOS, Windows, Flatpak) Drastically reducing installer sizes (more than halved).
+  * (Launchpad/Ubuntu) Using custom built packages of PySide6, meaning smaller installation and distro dependency.
+  
+## v0.3.0 (28 Oct 2022)
+
+**New**
+
+  * New completely revamped expression editor:
+  * Automatic closing of parentheses and brackets (can be disabled in settings).
+  * Syntax highlighting (can be disabled in the settings).
+  * Autocompletion is now available (for functions, variables and constants, object names and properties) (can be disabled in the settings).
+  * Object properties can now be used in expressions (e.g. if you have a point named A, you can use A.x to access its x value).
+  * Executable objects can be now be used in expressions (e.g. if you have a function named 'f', it's accessible using `f(<value>)`).
+  * LaTeX-rendered formulas are now used in the Objects and History tabs when LaTeX rendering is enabled.
+  * Errors in formulas are now reported in message boxes.
+
+**Changes**
+
+  * The Object Editor dialog has been completely reworked internally, resulting in notable performance improvements.
+  * Vast improvements to the objects system: names can no longer be shared amongst different objects.
+  * Disabled access to custom variable and function definition in expressions (can cause issues and vulnerabilities)
+  * When using the set position cursor, the position change is now saved a single history action.
+  * Distribution are now prefixed with an 'F_' to prevent confusion with X Cursors.
+
+**Added translations**
+
+  * Autocompletion categories (English, French, German, Hungarian).
+  * Expression editor settings (English, French, German, Hungarian).
+  * Expression syntax errors (English, French, German, Hungarian).
+  * On top of the above:
+  * Hungarian: v0.2.0 added text (thanks @ovari!)
+  * Spanish: Menu bars (thanks @Sergio Varela)
+  * You can contribute to translation on [Weblate](https://hosted.weblate.org/projects/logarithmplotter/logarithmplotter/#repository).
+
+**Fixed bugs**
+
+  * Fixing Texts not being properly recognized as texts when saving.
+  * Text's 'Disable LaTeX' property is now properly saved.
+  * X Cursors LaTeX rendering made the app crash.
+  * Attempting to insert special character no longer automatically saves the expression you're editing.
+  * Proper HDPI support for icons and buttons (note: HDPI is not available for the rendered canvas yet).
+  * Support for non-latin characters in variables (e.g. greek letters, subtext, suptext)
+  * Silent error when misentering variable names in the expression editor causing internal issues.
+  * Fixing some utils function simplifying parentheses when they shouldn't have.
+  * (flatpak and KDE SDK) Fixing the sometimes invisible buttons on the objects tab on startup.
+  * (macos) Application string version does not match LogarithmPlotter's version.
+  * (debian) (Normally) Fixing deb building.
+
+**Internal changes**
+
+  * Object dependencies are now registered on both the dependant object, and the object it's depending on.
+  * Objects now have a proper per-name registry.
+  * Object Editor Dialog has been reworked to use loaders insteads.
+  * Reworked the file loading system to be able to load dependencies properly.
+
