This is an (incomplete) retrospective timeline of the features added to the the [Kudamono Editor], mostly for self-reference. For a prospective timeline, refer to the [plans].

[Genres|paper-puzzle] are mentioned when newly added and also near changes that benefit them significantly. 
People may be mentioned if they are related to particular change.


April 2024

New genres:
- [Inturnal]
- [Bramble]
- [Rectyard]
- [Pointing at the crowd]
// - [Heterocut]

Classic genres: [Yin Yang], [Fillomino], [Slitherlink], [Choco banana], [Kurotto], [Kurodoko], [Tasquare]

	- More structured genre porting [plans], with expected release dates and claimable panels and metadata, to facilitate distributed collaboration
	**2024-04-04** @PinkHoodie added +9 genres to PuzzleSquare

	- [Version] history

	- faster display of rule panels in the modal;
	- genre-variant specific panels now in the genre file, with authorship, via ´´varipanels´´, not necessitating a specific variant template; **2024-04-19**
	- changed the backdrop colour to dark and added a distrete close button (@MartinEnder, @randomperson123) **2024-04-17**
	- the timer now pauses while changing window or tab (@Lorem) **2024-04-18**
	- aux marks preserved on winning in edit mode (@Menderbug) **2024-04-21**
	- cursors are now black on Mac OS, mimicking the defaults

Symbols and styles
	- Arrow symbols are now generated based on the geometry, rather than manually.
	- Cage-like styles are now possible (@PinkHoodie, @Anurag)
	- Grid division genres now using dashed gridlines (@dohz, @Menderbug)

	- multi-genre unit testing framework now memoises the common root state to speed up batch testing
	- style variegation delayed to provide more flexibility (hopefully not affecting performance)
	- searchable debug window for live checker
	- virtual palettes for colour name sharing (primary, secondary, neutral, marker)

**2024-04-04** Exported urls no longer contain newly-encoded aux marks (@Menderbug)
**2024-04-15** Puzzle galleries no longer display error checking inadvertently (cause: previously implicitly undefined argument started being populated by a sequential integer index number after refactoring). Thanks @Dohz and @PinkHoodie for reporting.
**2024-04-19** Regression immediately found by @PinkHoodie was fixed (cause: incomplete separation of recommended variants ´´recovariants´´ from the current loaded variants ´´variants´´)

**2024-04-19** Changed the headings style to always use small caps, for consistency; (@dohz)

March 2024

New genres:
- [Yajilin]
- [Touching Tails]
- [Parimony]
- [Lighthouses]
- [One-Two Zone]
- [Implicit Directors]

Global variants
- ´´knapp-daneben´´
- ´´liar´´

Local variants

Collaborations and API:
- Kudamono genres are now autodetected in PuzzleSquareJP (@Wand, @fff)
- genre and variant lists became available at: [kudamono/api/genres.txt|api/genres.txt] and [kudamono/api/variants.txt|api/variants.txt] (@5381)

- ability to aggegate any other item type, via ´´unifilters´´ (@ZacharyTalis)

- full separation of ´´symbol.encoletter´´ and ´´symbol.letter´´ for encoding purposes 

**2024-03-27** Recent search bar regression found by @PinkHoodie was corrected (cause: deep refactoring with partial test coverage)
**2024-03-28** Recent encoding regression reported by @5381, @PinkHoodie and @Rever was corrected (cause: more unit tests needed in the encoding module)

- loading a puzzle in another page other than the paper-puzzle-player page now causes the url to point to that page:
	- to encourage that as the canonical url (@dohz)
	- without breaking page navigation
		- unfortunately, history entries will still be added [until browsers fix this decade-old bugs|]

- cursors:
	- large mouse pointer removed, after polling a significant set of users in different communitites, and hearing heir thoughts;
	- added smaller, more conventional mouse pointer, albeit with a small symbol nearby, since the current action needs a signifier (@Yuyuki)
		- another browser bug found: on MSEdge, text inside svg cursors renders badly at small text sizes
	- predictive "cursor ghost" now less pronouced, transparent with a dashed outline 
	- immediate cursor change when toggling edit mode, as well as on starting the puzzle (after first cursor move)

//- the rules button now displays the rules directly in a window

	- Penpa batch import:
		- given lines: Line (tile-centered), line (tile-centered, free, in very limited scenarios)

Kudamono Genre Designer:

September 2023

New genres & variants:
- [Alcazar] by @Jerome
- [Simple Loop]: directions by @Millay
- [Masyu]: pentomino, snake, snake-edge by @Takmu

Kudamono Highlighter V3:
	- adds flexibility by separating each rule in two parts:
		- styling aspects now belong to the ´´glow´´ property, whereas
		- filtering aspects now belong to one of three related properties:
			- ´´consfilters´´ (staying constant)
			- ´´monofilters´´ (moving focus to a deeper or related aspect)
			- ´´polyfilters´´ (splitting a single focus into multiple independent foci)

	- changed the default font for:
		- consistency across devices, between mobile and desktop
		- solving an bug reported by @donnythenuts

	- it's now possible to distribute symbols to separate encoding meshes via the ´´symbol.encosuffix´´ property, which will be added to the url parameters ´´LI-´´ and ´´LS-´´ (expansions of ´´L´´ and ´´LF´´ respectively)
	- 3-digit positive integers are now allowed (@Wen)
	- Multi-line encoding via the ´´SI´´ and ´´SS´´ parameters

	- Puzz-link import now tolerates variant urls (those containing the string ´´v:/´´)
	- Penpa batch import:
		- tile types: shaded/absent, ice ^^[Parrot loop], [Ice dance pair] etc...^^
		- autodetect genre from puzzle title (beta)
		- new url types:
		- arrows and selected letters (S, G, F)

	- dragging different puzzle urls (within the same genre) to the desktop now produces distinctly titled links, no longer overwriting them, so it's easier to save puzzle drafts
	- easier navigation between puzzles of the same page, via next/previous buttons (@AndreaGilbert)
	- changestreams integrated with the homepage
	- variant information was added to the [new puzzle page|kudamono/new] and also to the page of each genre, in a more automated way (@Yuyuki) 

		- streamlined the cursor / cursor prediction modules
		- the cursor now shows in all occasions (@Menderbug)
	- editable fields:
		- changed colours to increase contrast (@Jubale)
		- fixed a bug of shortcut interference (@Jubale)

	- multi-letter fruits added to harvest
	- rules refactoring:
		- rule bank split into smaller modules
	- Multi-lines update:
		- segments moved to a new data structure named ´´supraforest´´ (solve lines) and ´´infraforest´´ (given lines). This will enable genres mixing different line types (e.g center vs edge, knight vs orthogonal, different colours, etc...).
		- for consistency, pencil aux marks (sketches) moved to an equivalent structure ´´sketvest´´

August 2023

- new genres: [flexible-counters], [redemption], [dance-and-dance]
- @kuchiwo broadcasted a series of seven Kudamono Livestreams: [1|KLV?g98NMJiTSuo], [2|KLV?Duueh1wiC7I], [3|KLV?YPCs6CK9QrE], [4|KLV?S5rUrz2C-Y0], [5|KLV?5Aq0om3AEHI], [6|KLV?ynDZbv1BqlM] and [7|KLV?1feS2GmoFf4] (uncovering several improvement opportunities)

API Changes:
	- lexicographic encoding is no longer used (except on legacy puzzles); replaced by standard numeric encoding (@semiexp)
	- board size now reflects the number of cells accurately via the W=´´1x2x3´´ parameter
		- ´´1x1 ´´ and ´´nx1 ´´ boards now allowed as the official minimum
	- [Myopia] and [Ant Mill] puzzles can also now be [imported directly|../p.html] from ****-style urls, so all genres common to both platforms are covered.
	- Penpa batch import page created, with support for:
		- numeric genres (1 number/question mark per cell) ^^[Soulmates],...^^
		- black and white pearls ^^[Masyu],...^^

	- redesigned the restart button [[restart]] to make it more distinct: [[reset]] (@Kays)

Miscellaneous Bug fixes:
	- fixed an issue with auto-mode ignoring lines (@Kuchiwo)
	- fixed an issue with some error styles being shaded by previous styles (@Kuchiwo)
	- url can now be shared as well (@MonokuroGreen)
	- 404 page was not displaying (@dohz, @Direkrow)
	- Safari bugs:
		-bookshelf displays each book at full width
		-puzzle miniatures patched so they at least are easily selectable (@AndreaGilbert)
	- added the ´´&LI, LIA, LIB...´´ family of encodings which can be used internally to encode e.g. differently-placed symbols each in its own mesh to avoid the need to reencode if placements are added/removed
	- removed property ´´geometry.tilesymboled´´. All symbols use the tile centre as a reference from now on, their precise placement is determined by the ´´symbol.placements´´ property.
	- removed property ´´geometry.tilelined´´. All lines use the tile centre as a reference from now on, their precise placement is determined by the ´´symbol.placements´´ property:
		- in addition to standard numeric placements, ´´tile-corner-mid´´ and ´´tile-edge´´ as geometry-aware placements
	- refactoring of the module loader
	- the unit testing system was extended to any variants


July 2023

	- New Genres ^^[Trizone], [Curve Sums], [Barbed Wire], [Nurikabe-loop], [Reachability]^^
	- First remixes of two distinct genres: ^^RB Masyu, Nurikabe Loop Masyu^^, under [Masyu]

	- [Brownies], [Square Jam], Simple Loop, [Masyu] puzzles can now be [imported directly|../p.html] from ****-style urls, either by:
		- swapping the domain directly by **site.domain** 
		- limitations: board sizes up to 9x9 only; numbers up to 16 only

// Link previews:
// 	- sharing a paper puzzle link will now display the associated puzzle metadata within the link preview (for more effective sharing on social media)
// 	- a genre-specific (but not yet puzzle-specific) picture is also now displayed

- board rotation and mirroring: (@MartinEnder)
	- has interface buttons available [[rotate-clockwise]], [[mirror-right]], for mobile
	- mirror shortcuts updated to the combo [[m shift, shift right]]
	- takes ´´symbol.placement´´ into account ^[Crosswall] and works on grids of variable dimension, such as rectagular or irregular hexagonal
	- takes directional symbols into account, such as arrows ^[X-sums], even on hex grids ^[RGB Loop]
		- via properties ´´symbol.rotagroup´´ and ´´symbol.orientation´´
- dragging:
	- symbol dragging now has a simpler drawing mode, different from line dragging (@Menderbug)
	- more control of the dragging area via the ´´dimension.dragpadding´´ property - this extra padding is not included when exporting pictures, for example (@Menderbug)
	- dragged symbols now rendered via ´´lightor´´ property
- mousewheel:
	- will only be used to rotate symbols if symbols are available and cursor is within the board; otherwise scroll the page normally

	- cursor now updates instantly when a symbols is changed via keyboard (@X-sheep) 
	- rare race condition tentatively fixed on drawing the puzzle miniatures (@direkrow)
	- bookshelf titles no longer slightly off-screen (@direkrow) 
	- pulsing inexistent buttons no longer tried (@direkrow) 
	- toggling highlighting is now instantaneous (@direkrow)

- solver for Crosswall by @semiexp
- Kudamono Editor debuts in GAPP

API Changes:
	- symbol encoding in genres with symbols outside the board was split in two fields:
		- ´´LEX´´ for symbols outside (ex-) the main board 
		- ´´L´´ for all other symbols (nothing changes in most genres)
	- this solved a few bugs and will make all genres future-proof in case of variants that add outside symbols, so that it won't affect past encodings
	- puzzles using the old encoding are redirected

		- tooltips added to every field (@Teal)
	- question marks can now also be inserted by typing [[?]] directly.
	- drag aborting (e.g by leaving the puzzle area or switching focus) no longer causes bugs

Symbols and aux marks:
	- better restriction of symbols when dragging based on their slot and placement (@Suzuki)
	- inserted symbols can now:
		- erase adjacent symbols via the ´´symbol.uncompass´´ property

	- added ´´state.geometry.basix´´ for a more robust usage of ´´symbol.placements´´ and split those as a submodule

	- the bookshelf now displays the correct page titles (@dohz)
	- fixed a critical display bug on some miniatures (@dohz)

	- ´´geometry.lineverged´´ property specifies whether lines can be drawn at the verge
	- encoding of "absent tiles" now always with the letter "x" for consistency across all genres; the same applies to visible blocker tiles
	- scopes ´´unlongloops´´, ´´unlongloop´´, ´´unlongtrack´´, ´´unlongorchard´´ added (these result in separate yet well-segmented tracks) ^^ [RB Loop], [RGB Loop]^^
	- scopes can now be prefiltered in all rules, by e.g.´´rule.placement´´ (affecting scopes: ´´buds´´, ´´numberedbuds´´)
	- added a ´´input.linemovemented´´ property for movement genres, with ´´input.linemovementedfruits´´ as a way to restrict movement to certain fruits; consequently removed the ´´figure-stepped´´ parameter 

	- rules:
		- moved ´´pics´´ and ´´descriptions´´ away from rules, into the ´´explanations´´ object (all genres)
		- property ´´rule.order´´ removed
		- extracted some rules into templates for reuse across genres and repurposing as live variant modifiers
	- drawing functions, for better testing and exposing data for visual unit tests
	- numeric genres, by adding the ´´numbers´´ property to replace function calls from within the genre file

April 2023

Collaborations: New Genres ^^[RB Loop], [Bouba Kiki Loop], [X_Sums], [Hit Points]^^

- API Changes
	- puzzle encoding in all numeric genres was standardised for consistency across genres, for several reasons:
		- facilitate development of automatic solvers, reducing the size of the"symbol dictionary"
		- accelerate genre porting, for the same reason
		- allow future expansions with larger and larger numbers, if ever needed
		- allow remixing of numeric genres in the upcoming Kudamono Designer
		- provide a means for multi-letter symbol encoding, if ever needed
All changes are backward-compatible - no puzzles will be affected.

- UI Changes
	- symbols in play mode can be coerced to stay within the board during input, even if positions outside are available in edit mode - via via the  ´´geometry.exsuprasymboled´´ property (@XSheep)
	- grid editing buttons updated for more consistency :shrink-right: and now adapted to the diamond grid (@Menderbug)
	- tool selection menu:
		- auto-tool mode (previous behaviour) became an option, albeit the default one:
			- the cursor now changes in real-time to reflect the predicted action 
			- the auto-button icon (composed of the first two actions) does not appear 
				- when there is a conflict preventing tool inference (e.g. ^^[dream-sequence]^^)
				- when no more than one action is possible (e.g. ^^[bonsai]^^)
		- symbol and line selection buttons now appear, on a genre-by-genre basis
		- likewise, marker and sketch buttons appear, when in aux mode:
			- alphabet aux panel now appears in some genres (@fff) ^^[tricklayer]^^
			- an auto marks button (:auto-mode:) appears when appropriate
	- numeric candidates aux marks ^^[X-sums]^^
	- keyboard shortcuts to select particular aux marks
	- a small prompt to load a puzzlestring from clipboard now appears when pressing [[ctrl v]]
	- the cursor is also drawn on touch devices:
		- without "hover predictions"
		- this forces a refresh of drawing targets, thus indirectly solving an "out-of-sync" bug (@Yuyuki)
	- hover predictions became more focused (@Menderbug):
		- only the main action is predicted (dropping the alternate action)
		- only one tool at the time (rather than all together at once)
		- lines display the predicted segment alongside the (more discrete) starting point
	- a lingering segment is no longer drawn after undrawing a line up to the very start (@dohz)
		- click vs drag disambiguation via the new ´´mode.clicking´´ property

- Page Changes
	- all text that is indirectly generated, rather than manually written, now displays with a different, **monospaced**, font, because:
		- it's nicer for readers to know when they are reading generated vs written text (even when generated text is based on manual data)
		- generated text tends to accumulate inaccuracies as new or more complex situations arise.
	- added aux mark keyboard shortcut tables
	- variant genre pages:
		- More complete authorship snippets under the rules text (@Dohz)
	- Page metadata for link previews no longer shows genre/variant authorship in the top title, because it was in many cases inaccurate. Instead it uses //Player & Editor// (@Dohz)
	- Rules text now:
		- displays a pass(:pass:)/fail(:fail:) icon, if appropriate, where available
		- can be copied to clipboard, via a button below, for quoting on external sites (@XSheep)

- Other fixes
	- shading a number no longer necessarily hides it underneath (@Menderbug)
	- overlapping number and symbols now insertable together for more convenience ^^[dream-sequence], [flashlights-crossing]^^

- geometry:
	- new property ´´geometry.exmarked´´ specifies whether marks are allowed outside the board (defaults to false), by analogy with ´´geometry.exsymboled´´ property 
	- new property ´´geometry.wholelinemesh´´ used instead of ´´geometry.linemesh´´ when the ´´geometry.linedivided´´ property creates a smaller divided mesh, not always desired
- **visual** unit tests added to the test suite
	- ´´buds´´ (via the ´´appearance´´ property)
	- ´´lands´´ (via the ´´kappearance´´ property - main difference is that lands can be drawn several times in the same spot)
- new scopes:
	- ´´frukingdom´´, ´´fruterritory´´ (keeps region within fruit specified after ´´:´´ )
	- ´´unfrukingdom´´, ´´unfruterritory´´ (outside region without touching the fruit specified after ´´:´´)
	- ´´:number´´ and ´´:letter´´ scope filters (expanded to the actual numbers or letters present before checking)
	- individual scopes for a single ´´bud´´ or ´´number´´
	- ´´:midpoint´´ scope for segment midpoints (for use with the adjacency rule family)
- refactoring:
	- common line properties moved into templates such as ´´template-line-normal´´, ´´template-palette-orange´´, possibly causing slight uniformisations in the appearance of some genres
	- all numeric genres may no longer specify their own ´´alphabeto´´ dictionary, relying in a shared dictionary
	- erase ´´symbol.photoplacement´´ property and all related functions
	- style properties:
		- renamed to canonical values in all genres
		- are nevertheless renamed by default upon initialisation, for robustness 
		- behaviour of ´´opacity´´ and ´´lineOpacity´´, ´´lineOpacitor´´ was fixed, in particular around grid
	- rule highlighting preserves original order when several errors are applied in succession in the same spot

	- property ´´render.container´´ no longer needs a pre-dot
	- property ´´targetoo[layer]´´ memoises current drawing contexts for each canvas, speeding up drawing
- scopes:
	- Negative scopes, via the ´´:!´´ operand, to specify regions not containing a fruit
	- ´´nets´´, ´´longnets´´, ´´net´´ and ´´longnet´´ scopes consolidated for use in tangram-like genres
	- ´´numbers´´ and ´´number´´ scopes
		- major simplification of all numeric genres
- geometry:
	- property ´´geometry.linedivided´´ now explicitly marks when lines must be subdivided ^^ [Parrot Loop], [Flashlights] ^^
	- masked symbols are excluded from the tabula by default via property ´´geometry.unmasksymbolmesh´´
	- a small encoding problem with non-unit compasses was fixed
	- removed outdated properties ´´geometry.terriplacement´´ and ´´geometry.terrifruits´´
- scattered refactoring:

	- more symbols are inherited, e.g ´´symbol-model´´ template for pipes, variety, etc...
	- removed ´´RD´´ property that was used to disable rules selectively

- expanded the undo module to allow infinite parallel undo/redo/restart stacks
- transparent event handling using ´´false´´ as return value to signal that the default action should not be prevented
