Number overhaul.

Polar number input:

single-click to add previously saved or typed number
single-click on any number to erase
single-drag gesture to add any number (rotate the knob clockwise to increase, counterclockwise to decrease)
single-drag gesture to erase any number (small drag)
single-drag gesture to correct any number (rotate the knob to adjust from previous number)
suport for infinite ranges (multiple rotations of the knob will keep increasing/decreasing)
support for minimum, maximum and exclusions in range (e.g. number 15 in Corner Meeting)
intuitiveness via clock/crank metaphors, however with numbers spaced 1/10^th (instead of 1/12^th) as decimal arithmethic is easier (Martin Ender (Menderbug))
predictability as dial numbers are always in the same consistent position (whether adding anew or correcting)
semitransparent dial, not obstructing underlying board

Negative numbers

encoding for negative numbers naturally expands previous parenthised encoding
negative numbers added to selected genres, such as Foreshadow

Thanks Mornicus, Endagorion, Martin Ender (Menderbug), Anurag Sahay, PinkHoodie, fff, Nishinanntoka for ongoing feedback (work in progress).

Encoding.

reencoded genres now include an encoding (version) number in the url, via the E field. The default (zero) is not shown.
pipes were reencoded Hamiltonian Plumbers, Shirokuro Pipe シロクロパイ
short arrows were reencoded X-Sums, Hit Points ヒットポイント
support for arbitrary line types via encogroups

Internal.

virtual templates extended to the min/max binomium
svg-based rendering

Fixes.

day regression in number templates reported by PinkHoodie, Laclale (cause: file misnaming) Thu. May 23^rd 2024

Genres:

New: Inturnal, Bramble, Rectyard, Pointing at the Crowd //Heterocut
Classic: Yin-Yang しろまるくろまる, Fillomino フィルオミノ, Slitherlink スリザーリンク, Choco Banana チョコバナナ, Kurotto クロット, Kurodoko 黒どこ, Tasquare たすくえあ

Project:

More structured genre porting Kudamono Plans, to facilitate distributed collaboration, with:

expected release dates
claimable panels and metadata

Kudamono Version History history
genre pages display more information about running unit tests, puzzle listing schedules, etc… and even a notice for genres temporarily broken.
going through gene tags to fix them (dohz) NOTE: could there be a way to auto-tag, based on the used rules?

UI:

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; Fri. Apr 19^th 2024
changed the backdrop colour to dark and added a distrete close button (Martin Ender (Menderbug), Randomperson123) Wed. Apr 17^th 2024
the timer now pauses while changing window or tab (Lorem) Thu. Apr 18^th 2024
aux marks preserved on winning in edit mode (Martin Ender (Menderbug)) Sun. Apr 21^st 2024
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 Sahay)
Grid division genres now using dashed gridlines (dohz, Martin Ender (Menderbug))
Ability to specify symbol.textOpacity separate from general opacity

Panels:

changed the backdrop colour to dark and added a discrete close button (Martin Ender (Menderbug), Randomperson123) Wed. Apr 17^th 2024
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; Fri. Apr 19^th 2024

Timer:

the timer now pauses while changing window or tab (Lorem) Thu. Apr 18^th 2024

Internal.

Arrow symbols now generated based on the geometry, rather than enumerated manually.
multi-genre unit testing framework now memoises the common root state to speed up batch testing
searchable debug window for live checker
style variegation delayed to provide more flexibility (hopefully not affecting performance)
virtual palettes for colour name sharing (primary, secondary, neutral, marker)
efficient point snapping to avod numeric errors
auto-assign symbol layers based on their (already unique) letter
ability to style aux marks reactively (e.g to make them disappear or fade in certain situations)

Fixes:

Exported urls no longer contain newly-encoded aux marks (Martin Ender (Menderbug)) Thu. Apr 4^th 2024
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. Mon. Apr 15^th 2024
Regression immediately found by PinkHoodie was fixed (cause: incomplete separation of recommended variants .recovariants from the current loaded variants .variants) Fri. Apr 19^th 2024

API:

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

UI:

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 (ゆき❄ (Yu-ri))

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)

empty boards now never cause a winning state (by default)
aux marks:

dragging bug fixed (Blaž Urban Gracar, Seren, and others)
bug reported by Wisteria Fall fixed
clarified auto button tooltips
toggling aux mode remembers last tool used
scroll wheel also cycles through aux marks in aux mode

visuals:

line stripes now appear at consistent perceptual distances, no matter the angle;

a perfomance improvement
out-of-the-box LAB colourspace support (Eli Doris (TwoHoleStraw))

slightly more stable colouring (Jeffrey Bardon (IHNN))

Setter/Solve switch:

when inserting a symbol/mark, switching to/from edit mode has the lowest precedence (Lennard Sprong (X_Sheep))

Masyu ましゅ: pentomino, snake, snake-edge by takmu (たくあん)

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)

Font:

changed the default font for:

consistency across devices, between mobile and desktop
solving an bug reported by Donnythenuts

API:

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

Page:

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 (Andrea Gilbert (Clickmazes))
changestreams integrated with the homepage
variant information was added to the new puzzle page and also to the page of each genre, in a more automated way (ゆき❄ (Yu-ri))

UI:

cursors:

streamlined the cursor / cursor prediction modules
the cursor now shows in all occasions (Martin Ender (Menderbug))

editable fields:

changed colours to increase contrast (Jubale)
fixed a bug of shortcut interference (Jubale)

Internal:

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

Collaborations:

new genres: Flexible Counters, Redemption, Dance and Dance ダンス.アンド.ダンス
Kuchiwo Tsugumi (Competor) broadcasted a series of seven Kudamono Livestreams: 1, 2, 3, 4, 5, 6 and 7 (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

Interoperability:

Myopia and Ant Mill puzzles can also now be imported directly from puzz.link-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 ましゅ,…}

url can now be shared as well (モノクログリーン)
404 page was not displaying (dohz, Mitchell Clarke (DireKrow))
Safari bugs:

bookshelf displays each book at full width
puzzle miniatures patched so they at least are easily selectable (Andrea Gilbert (Clickmazes))

Internal:

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-vertex-mid and tile-edge as geometry-aware placements

refactoring of the module loader
the unit testing system was extended to any variants

Collaborations:

New Genres ^{Trizone サントイッチ, Curve Sums, Barbed Wire, Nurikabe Loop 面積リンク, Reachability}
First remixes of two distinct genres: ^{RB Masyu, Nurikabe Loop Masyu}, under Masyu ましゅ

swapping the domain directly by pedros.works
limitations: board sizes up to 9x9 only; numbers up to 16 only

UI:

board rotation and mirroring: (Martin Ender (Menderbug))

has interface buttons available (rotate-clockwise), (mirror-right), for mobile
mirror shortcuts updated to the combo ⇧M (shift+m) → ⇧ (shift+right)
takes symbol.placement into account ^{Crosswall クロスウォール} and works on grids of variable dimension, such as rectagular or irregular hexagonal

via properties symbol.rotagroup and symbol.orientation

dragging:

symbol dragging now has a simpler drawing mode, different from line dragging (Martin Ender (Menderbug))
more control of the dragging area via the dimension.dragpadding property - this extra padding is not included when exporting pictures, for example (Martin Ender (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

buttons:

symbol icons now display slightly larger, thus more easily visible (Mitchell Clarke (DireKrow))
aux mark keyboard shortcut tooltips added (Mitchell Clarke (DireKrow))

aux marking:

shortcut Ctrl/⌘ (ctrl+space) now toggles aux mode (Mitchell Clarke (DireKrow))

Collaborations:

New Genres ^{Tetritory テトリトリー, RGB ループ Loop, Zero One Lines ゼロイチライン, Achtelwenden}
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
standardised letter encoding for letter genres, e.g. cypher clues (uppercase)
numbers extended up to 99 (Blaž Urban Gracar)

UI:

one can now drag away from the puzzle by clicking on the surrounding area (David Millar)

double-diagonal aux marks (Martin Ender (Menderbug))

Variants:

multiple variants can now be added to the same page, and render correctly
consolidated the following pages (dohz):

The ^Myopia page now contains the variants Full Myopia and Unequal Lengths Myopia
The ^{Chess Snake & Variants} page now contains Chess Snake asa well as Chess Path
The ^{Square Contact} page now contains Contact and Hex Contact

significantly expanded the ^{Masyu ましゅ} page, now containing a myriad of atomic and combined variants for perusal, with good example puzzles (dohz, Teal)
commas as variant separators no longer break on url export (Teal)
variants that drop (instead of adding) certain constraints, aka. "optionals", are fully supported

Internal:

generalised variegation can now be applied to any scope

both hue and lightness variegation are supported, via the styles varihue and varilightness

Collaborations: New Genres ^{Turtle Shell Loop 亀甲の輪, Gravel, Crosswall クロスウォール, Starry Knights}.

Variants and rule elements (API change):

variants can now be added via the field &V=

the old "verified by" field (formerly &V=) was folded into the "with thanks to…" field &K= as this was the most common scenario

the growing list of variants is specified at the variants draft page
common rule elements can be added exactly the same way

Interface:

menus:

Middleclick now toggles between edit and play mode (Martin Ender (Menderbug))
derived button colours (Martin Ender (Menderbug))
alternative keyboard shortcuts are now possible, as the symbol.shortcuts property now accepts lists too
"lingering" cursor bug on mobile (Martin Ender (Menderbug) and ゆき❄ (Yu-ri))

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

Collaborations: New Genres ^{R・B ループ Loop, Bouba & Kiki Loop, X_Sums, Hit Points ヒットポイント}.

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 (Lennard Sprong (X_Sheep))
grid editing buttons updated for more consistency and now adapted to the diamond grid (Martin Ender (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 Gardening})

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 () 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 (ゆき❄ (Yu-ri))

hover predictions became more focused (Martin Ender (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()/fail() icon, if appropriate, where available
can be copied to clipboard, via a button below, for quoting on external sites (Lennard Sprong (X_Sheep))

Other fixes

shading a number no longer necessarily hides it underneath (Martin Ender (Menderbug))
overlapping number and symbols now insertable together for more convenience ^{Dream Sequence, Crossing Flashlights}

Internal:

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

New Genres: ^{Zukei Puzzles, Shikaku Cut, Chess Avoidance, Chess Loop, Numericlone}.

Kudamono Genre Designer:

playground page with:

live refreshing (whilst keeping focus)
ability to load any combination of genres and templates, and overwrite any aspect
IDE-style code editing shortcuts for a single selection:

duplicating, moving and removing line groups
opening or closing braces (multiple types), even around the selection
(de)indentation; preserving indentation on newline
etc…

basic export
ability to sync serials with code for live editing of rule examples and unit tests

Features and Fixes:

Geometry:

diamond grids are available (Martin Ender (Menderbug))
adaptive zoom now takes into account removed tiles (Lennard Sprong (X_Sheep))
hexagonal grids:

url encoding/decoding now bug-free ^{Zukei Puzzles}
face-down hexagonal grid tiles now rendered w/ correct size
shifting/mirroring/rotating the board no longer cause rounding errors (again), as newly added points now snap to the original mesh if sufficiently close

geometric properties in serials are initially memorised and re-added (when different from default ones)

UI Changes:

feedback button () within the about menu ()
mobile fixes

opening the keyboard on mobile (or resizing any window) no longer locks the live parameter ui
all UI buttons were raised a little on vertical screens to avoid being covered by mobile browser menus

eraser buttons were consolidated as a single button, which:

erases solution and aux marks, when in play mode
erases everything, when in edit mode

input lag alleviated (Thomas Luo (tluo))

Galleries:

Puzzle pictures are now rendered consistently, scaling down to fit available space (instead of being cropped)

Transcriptions sped up with the new default "batch transcribe" workflow reduces context switching
Live parameters were refined to allow more complex data entry ^{Zukei Puzzles, Shikaku Cut}

Internal:

rendering and highlighting:

added colour:”from-prebud” property to style each segment colour based on the colour of the fruit it starts on
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:

Genre—>genro for genre objects
more symbols are inherited, e.g symbol-model template for pipes, variety, etc…

Symbols with multiple placements/forms can now be dragged interchangeably ^{Subway, Subwhirl, Hamiltonian Mazes}

Discontinued:

Spider input mode for ^{Dream Sequence, Unparalleled, Zig Zag, etc…} the line would be drawn freely, but it stick to any symbols, like a spider's web (this didn't work well in practice).

Internal:

Finer control of co-territories, via the geometry.unobstacles property (specifies which fruits are "transparent")
Ability to hide certain symbols on win, via the symbol.unwinned property (ゲサク (GESAKU))
Ability to specify other layers to erase when a symbol is added, via the symbol.unlayers property (ゲサク (GESAKU))
Aux symbols, which are in between marks and symbols (affect error checking, but are erased via the aux ui buttons), via the symbol.auxed property

Auto-exclude solution and aux marks from exported links
alternate symbols in monochrome mode ^{Decoration Tree}
input modes:

locked compass input mode ^{Ice Dance Pair アイスダンス・ペア}
improved rectangular input mode ^{Ionic Squares,Rectangle Puzzles}

timer:

Upon solving a puzzle, a small timer will show up the elapsed time, in the format MM:SS (minutes, seconds) - (Chiel Beenhakker (bakpao)) Fri. Dec 9^th 2022
Some players find timing essential, others may find it stressful. So a compromise was sought between making this feature available and discoverable, but also discreet.
As a bonus, clicking the time will copy it to the clipboard for e.g. easy sharing in competitive forums.
