+### Breaking Changes
+- Spaces are not allowed in hex numbers anymore but undorscores are.
+  It caused problems since 0xAA B could not be unambiguously parsed (e.g. it can be 0xAAB or 0xAA B, where 'B' is a unit for 'bytes', so make it explicit by writing 0xAA_B).
+### Features
+- Dark Theme ![img](https://trello-attachments.s3.amazonaws.com/558a94779b3b3c5d89efeaa6/5fe0ae9f0b9791732fdf6901/1e4fbe68e3e3e0f2b369b29d853881df/D10nAPmBHz.gif)
+- Render command optimizations, reducing render command count by around 40%
+  (gutters, line number- and result backround 
+  are now rendered only once as a big rectangle and not line by line).
+- Active references (variables and line refs in the cursor's row) are now just underlined
+  and the referenced lines are not highlighted fully only their left and right gutter.
+  (Look at the image below)
+- Results where a denominator is a unit (e.g. 5 / year) are now rendered in a more user-friendly way (e.g. instead of `5 year^-1` it is `5 / year`)
+  ![img](https://trello-attachments.s3.amazonaws.com/558a94779b3b3c5d89efeaa6/5fe0ae9f0b9791732fdf6901/b22cf68c1bb85d890bf1363e55e94435/0.0.3_unit_denom.png)
+- Automatic closing parenthesis/braces insertion when the opening one is typed
+- Automatic closing parenthesis/braces deletion when the opening one is deleted
+  ![img](https://trello-attachments.s3.amazonaws.com/558a94779b3b3c5d89efeaa6/5fe0ae9f0b9791732fdf6901/a2b3699e56eb91dd74909091aa903098/0.0.3_parens.gif)
+- Automatic parenthesis/braces wrapping around selected text if opening one is typed while
+a text is selected
+  ![img](https://trello-attachments.s3.amazonaws.com/558a94779b3b3c5d89efeaa6/5fe0ae9f0b9791732fdf6901/a4f947f869a4d4537043cc962551da8f/0.0.3_wrap.gif)
+- Matching parenthesis are highlighted if the cursor is inside them
+  ![img](https://trello-attachments.s3.amazonaws.com/558a94779b3b3c5d89efeaa6/5fe0ae9f0b9791732fdf6901/9efb7959ddc5fde61f395f79f2027d9c/0.0.3_paren_hilight.gif)
+- The note can be saved with ``ctrl-s`` (Though it is still saved automatically when there is no user interaction)
+- It is possible to apply units directly on Line References or Variables, e.g.
+  ```
+  var = 12
+  var km
+  ```
+  The result of the second line will be ``12 km``
+- Parsing improvement: Now the parser are smarter in deciding what is an operator (e.g. 'in' in `12 m in cm`),
+  a unit (`12 in` which is 12 inch), or a simple string (`I downloaded 12 GB in 3 seconds`).
+  Now it is even possible to evaluate this string `12 in in in`, which is equivalent of `12 inch in inch`
+  ![img](https://trello-attachments.s3.amazonaws.com/558a94779b3b3c5d89efeaa6/5fe0ae9f0b9791732fdf6901/1f851d6b80e265dec9b6d055e2ae90b0/0.0.3_smar_parsing.png)

+- Max row count was increased from 128 to 256
+- e (Euler's Number) was added, currently as a function (`e()`)
+- Invalid argument types for functions are highlighted as errors (See image below)

+### Changed
+- When opening a not empty note, the result panel now tries
+to be as close to the editor as possible to have a better
+  overview about calculations and their results.
+- GitHub and website links were added to the NoteCalc page
+- Strings at the frontend are now rendered char by char. It is necessary
+to be able to place the cursor at the right place, since the text rendering
+  does not guarantee that a single char takes exactly 'char-width' pixels.
+- Overlay canvas (the canvas above the app canvas) was removed. It was used to draw
+  overlay effects (e.g. pulsing), but it was problematic since it needed alpha blending,
+  which wasn't always nice and console frontend support is limited.
+  Now pulses are rendered above "BelowText" layer and below the "Text" layer.
+- underscore is allowed in binary numbers (e.g. ``0b11_00``)
+- Parenthesis have different color than operators.
+- Remove `Vec` and dynamic allocation from unit parsing and operations.
+- Replaced all unit `RefCells` to `Rc`, it was a mistake to use `RefCells` in the first place.
+- Matrices cannot be deleted anymore by `DEL` or `BACKSPACE`, ctrl is needed
+
+### Fixed
+- Dead characters (e.g. '^' on a hungarian keyboard) were not possible to type
+- Longest visible result length was calculated wrongly when there were multiple headers
+in a note, which affected the result panel size.
+- `sum` variable get emptied at #Headers
+- Char width at the fonrend is now integer, ceiling upward. It caused issues
+with rendering (widths of recatngles were float as well and did not always fill up
+  the required space)
+- Underlines and line reference background rectangles were rendered even if they
+were outside of the editor area
+- `ctrl-x` did not copy the selected text
+- Units in the denominator behaved buggy. now expressions like this works well
+  ```
+  tax A = 50 000/month
+  tax B = 50 000/year
+  (tax A + tax B) * (1 year)
+  ```
+- u64 values can be parsed correctly (e.g. 0xFFFFFFFFFFFFFFFF)
+- Bitwise operations now work on u64 values
+- Negative numbers can be presented in binary and hex form
+- Line reference pulsing was called each time a cursor was pressed on the line ref's line, causing
+flickering
+- 'Line normalization' (the process where the referenced lines' id is normalized to the referenced line actual line number)
+  could be undo with ctrl-z
+- Bitwise shifting operators (`<<` and `>>`) used wrapping, resulted in unwanted situations. Now it is an error
+to use larger shift operands than the underlying integer representation (u64 currently)
+

 ### Breaking Changes
 `--` does not set the `sum` variable to zero, but every header does
