CHANGELOG.md

Changelog

Note: Many earlier versions are not specified, that's too much work.

When a @types dependency updates, they almost always don't affect anything.

v0.36.3

• (css) Fix strategy disable not changing link color + slightly more accessible disabled color

v0.36.2

• (code) Use new Set methods, simplifies code. This shouldn't break support for old browsers.

v0.36.1

• (css) Fix explanation changing the size of Aside
  • Chain explanations now include zero width spaces to break-word nicely.

v0.36.0

• (use) Fix ANOTHER massive bug: editing multiple cells now works and is consistent with the visuals
• (use) Ctrl+A to select all cells

v0.35.1

• (use) Fix massive bug in cell keyboard nagivation, where pressing an arrow key would focus the next cell and select the next next cell
• (a11y) Expand abbrevation (strats ⇒ strategies)
• (css) Fix some incorrect rtl display

v0.35.0

• (use) Multiselectable cells! Select multiple cells at the same time with Ctrl+Click
  • Instead of being turned off, a selection will be disabled when clicking off. This is to prepare for the on-screen keyboard later.
• (use) Diagonal keyboard movement!!! Holding Up and Left at the same time will now go both directions!
• (use) When editing a cell: the functions of Backspace and (Shift or Ctrl)+Backspace have been switched.
  • Previously, Backspace would delete all candidates. Now it adds back all candidates.
    • Additionally it sets pretend to true, so it will still change to a single digit when typing.
  • (Shift or Ctrl)+Backspace used to add back all candidates; now it deletes all candidates.
• (use-bug) Previously, if a bunch of keypresses happen to cause a cell to end up at 9 candidates again, it was not a condition to pretend as described above. Now it is. Personally, despite my extensive usage, this edge-case has not been run into yet so I do not know if this should be reimplemented.
• (temp-docs) The way the Tabs and the Cells handle multiple keypresses at the same time is different. Specifically, Cells use a global event handler, while Tabs only have a local event handler. This means that for example, holding down two keys then focusing the Tabs, the Tabs would only have one key stored on repeat.

v0.34.0

• (use) Add "explanations" for some strategies.
• (ui) Fix margin in aside causing 1.5rem misalignment in two-column mode.
• (ui) Increase amount of blank space at the bottom of the page in one-column mode. (20vh ⇒ 25vh)

v0.33.0

• (a11y) Theoretically, screen readers can tell now that a candidate is eliminated (or rarely, added).
• (a11y) Use p, span, and layout: grid instead of table et al. As a side effect, the highlighting for cells is slightly bigger.

v0.32.0

• (fix) Subtle bugs in pairCoversGroup causing incorrect eliminators
• (use) pairCoversGroup extension when the pair sees each other
• (code) Typescript v5 is necessary for tuple overload

v0.31.0

• (ux) Do not lazy load anything
  • I will add back this later. A better experience is loading things silently but ahead of time.
  • 100% of the time, loading cells will be done. A better candidate is the strategies, or in the future, the settings page.
• (ui) When a strategy errors or solves, stop instead of going to "Check for solved"
• (bug) Fix theoretical bug where a skipped disabled strategy becomes undisabled, but the solver thinks the strategy was already done so skips it the second time. This is a true edge case scenario because the only way I can imagine a strategy being done twice is some undo shenanigans.
• (bug) Fix theoretical bug where if the successcount was -1, it was interpreted as an error. This could theoretically happen if the user deletes a solved cell. "check for solved" then succeeds because the amount solved changes by -1. This is intentional and not an error. There are two properties that represented success, the property that was visualized did not have the bug, and did not say "Error". Instead there's a subtle requirement to press "Step" twice for "check for solved". This was fixed by only having 1 property.
• (bug) Fix how the strategy wouldn't be retried when clicking step after a manual edit.

v0.30.0

• (use) pairCoversGroup
