v0.60

Version: Exolve v0.60 April 1 2020

• For orphan clue placeholders, use middle dots (···) instead of question marks
  (???) so that filled placeholders can more readily be visually distinguished
  from unfilled ones.
• Minor bugfixes for linked clue number rendering, when the linked numbers
  are non-numeric.

Version: Exolve v0.59 April 1 2020

• Do proper styling of clue numbers for linked clues: let them spill into
  the clue column, and indent the clue column.
• Enable 'clear this' button if there is an anno (just like 'reveal this')
• In 'reveal/clear this' set/reset clue solved state and colour even for
  orphan clues.

Version: Exolve v0.58 March 26 2020

• Go back to using old var names such as currentRow, as some customizePuzzle()
  scripts depend on them.
• Add a test (test-customize-puzzle.html) to make sure we do not change these
  names going forward.
• Increase max allowed grid size to 100.
• Add the following new exolve-options:
  • grid-background:[html clolor]
  • offset-left:[x]
  • offset-top:[y]
    The offset-left and offset-top options allow you to move the position of the
    grid (for example, if you want to paint additional artwork around the grid,
    using customizePuzzle().
• Add an exolve-credits section (repeatable).
• Expose numCelldFilled as a global (numCellsToFill is already there)

Version: Exolve v0.57 March 25 2020

• Only allow manually setting/unsetting a clue's "solved" state for clues
  that do not have all cell locations known.
• When clicking on a black cell or the title (to unhighlight active cells),
  also unhighlight active clues.

Version: Exolve v0.56 March 23 2020

• Mainly a revamp of tab navigation, to take into account various cases
  involving diagramless cells, clues without cells specified, etc.
• When on a diagramless cell or a cell without a known clue, the clues strip
  will now cycle through only "orphan clues" with the < and > buttons in it.
• Darken the current cell more than the rest of the active cells.
• Add small triangles to indicate the current direction. Unobtrusive and
  harmless (perhaps reassuring) normally, and quite useful on diagramless cells.
• Allow clicking on clue numbers in the clues lists, to manually toggle "solved"
  state (i.e., the light-blue colour). Useful for jigsaw puzzles.

Version: Exolve v0.55 March 9 2020

• Add prev/next clue buttons in the current clue strip, helping navigation
  on mobile devices where tab/shift-tab is not doable.

Version: Exolve v0.54 March 5 2020

• Bugfix: focus on placeholder in a clue only if it actually exists!

Version: Exolve v0.53 March 5 2020

• Turn on orphan-clue placeholder enrtry areas even if diagramless cells are
  present--just turn off the copy-from-placeholder buttons (as only one cell
  will be active if it is diagramless).

Version: Exolve v0.52 March 4 2020

• Bugfix: tab-navigation in the clues list also moves focus to the placeholder
  input area, if present.
• Add hide-copy-placeholder-buttons option to not show copy placeholder buttons
  if desired.

Version: Exolve v0.51 March 3 2020

• Allow tab/shift-tab for lights even when they do not have a known clue
  associated.
• Use a shorter separator string for saving state (but support the older one
  too).
• For nodir clues without cells specified, create placeholder text-entry areas.
  Also add buttons to transfer into active cells.
• Bugfix: only if a tab/shift-tab is usable for navigation do we now prevent
  default browser behaviour.
• Bugfix: When entering answers, do not make the cursor jump to the end.
