Release Notes

TempoWeave Studio v26.511.1

New Features

• Section Notes and Marked Sections Only print. Each warp or weft Section Marker now has an optional multi-line Notes field, accessible by editing the section (Section Assembly panel → right-click → Edit, or the Section dialog when marking a new section). Two new checkboxes in Page Setup — "Warp Marked Sections only" and "Weft Marked Sections only" — restrict Print Threading and Print Treadling to the marked ranges, with each section's Notes printed as a header above its threads or picks. The same two checkboxes are mirrored in Weaver's Writeup → Report Contents. Falls back to printing everything when no markers exist on that axis. Per-document, saved with the WIF.

Bug Fixes

• Fix #197 follow-up: Section Assembly "Use Color Assembly" checkbox is now fully wired. The minimum fix in v26.510.1 made Print honor the checkbox for the current session. The flag now persists inside the TWA file, survives save and reopen, and also drives the Generate step (not just Print). Previously the checkbox had no effect on Generate, did not persist, and only filtered Print output until the file was closed.

TempoWeave Studio v26.509.1

Improvements

• Yarn Catalog: large curation pass on bundled yarns (#193). Yarn-line classification, fiber content, mercerization status, and other metadata populated across many previously-incomplete rows — including Harrisville Highland and Shetland, Jaggerspun Heather and Zephyr, Lunatic Fringe Tubular Spectrum, Supreme 8/2 and Merc 3/2, Valley Merc Cotton, Venne Mercerized Cotton, Venne Organic Cottolin, and more. Hovering a yarn in the palette now shows its proper line/fiber, making it much easier to tell yarns apart when mixing different lines in one project.

• Yarn Catalog and Section Assembly: column widths stay where you set them — adjusting a column in the Catalog, My Yarns, or any of the six Warp/Weft Section Assembly trees no longer reverts after Edit/Add/Delete operations. Widths now also persist across app restarts.

Bug Fixes

• Yarn Catalog: removed stray Color box from Brassard yarn-line rows — Brassard Cotton 16/2, 8/2, 8/4, 8/8, 16/8 (Mop), and Brassard Boucle were showing a pale grey-blue rectangle in the Color column at the yarn-line level. Color is meaningful only at the leaf-color row level; cleared the stray values in the bundled catalog.

TempoWeave Studio v26.508.3

New Features

• Yarn Catalog now available to Lite and higher (previously Core+). Lite weavers can open the Yarn Catalog and assign yarns to threads. Clear Palette and Import/Export Yarns also in the 508.2 update.

Improvements

• Variegated yarn — Continuous mode now renders correctly across picks and threads. Previously, every pick (or every warp thread) treated the yarn as if a fresh strand entered from the same edge, so the color pattern appeared to "restart" at every new pick. Continuous yarns now follow a true back-and-forth path — weft alternates left-to-right then right-to-left between picks, warp alternates top-to-bottom then bottom-to-top between threads — matching how a single long strand naturally winds through the cloth. Existing continuous-mode variegated drafts will render visibly differently.

• Tooltips added to Thread Offset and Offset Variation in the Yarn Editor's variegation panel, with one-line explanations of what each control does and the note that variation is deterministic-per-thread (the same draft always renders the same way).

• Yarn Catalog: Clear Palette and Import/Export Yarns now available to Lite tier — completing the Yarn Catalog feature set rolled into Lite in v26.508.1.

• Section Assembly column widths persist: Adjusting a column in the Warp/Weft Assembly tree no longer reverts after Up/Down/Add/Edit/Delete operations. The Name column is now 200pt by default so most section names display fully without manual adjustment.

• Section Assembly toolbar wraps in narrow panels: When the panel was docked narrow, buttons past a certain point (Up/Down/Delete/Generate/Print) were silently clipped off the right edge. They now wrap to a second row instead of disappearing.

Bug Fixes

• Fix Section Assembly Generate when the panel is undocked. Previously the success toast appeared but no preview tab opened.

• Fix Print Color Card crash on large or A4-paper drafts: Resolved a DocumentLayoutException; row width reduced to fit A4 portrait without needing landscape.

• Fix Tromp as Writ crash: Prevent IndexOutOfRangeException when the cloth buffer has temporarily fallen out of sync with the active draft dimensions.

• Fix Prepare Threading WIF crash: Same root cause as Tromp as Writ, now resolved on both paths.

• Fix Drawdown click crash in Fabric Analysis: Clicking past the absolute buffer cap is now a no-op instead of throwing IndexOutOfRangeException.

TempoWeave Studio v26.426.1

New Features

• Treadle Status Overlay: Floating panel over the cloth canvas in Weave Assistant showing expected and detected treadles for each pick. Color-coded cells: blue (expected), green (correct), red (wrong treadle). Draggable, toggleable via toolbar checkbox. Works in all modes.

• Weave Assistant Treadle Grid: The left-side pick grid now shows treadles instead of shafts, matching what weavers physically interact with.

• Weave Assistant OK Beep and Error Beep: New configurable chime settings in Weave Assistant for successful pick advancement and wrong-treadle detection. Custom WAV support with browse and test buttons.

• Always Show Scrollbars: New setting in Default Settings to keep scrollbars visible at full size instead of auto-hiding. For weavers who find the disappearing scrollbars hard to use.

• Default Shed Mode: Rising or Sinking shed default can now be set in Settings, applied on startup.

Improvements

• Ctrl+Scroll Zoom: Fixed Ctrl/Cmd+scroll wheel zoom — now properly intercepts before the ScrollViewer consumes the event. Zoom works reliably regardless of scroll position.

• Thread Markers: Replaced thick blue line markers with small translucent triangles that don't cover grid content.

• Print Color Card: Fixed crash on large drafts with many threads or colors. Content now paginates across pages instead of overflowing.

• Print Threading: 50 threads per row on A4/Letter portrait, even row endings, right-aligned last partial row.

Bug Fixes

• Fix localization for unsupported languages: Users with system languages that don't have a locale file (e.g. Dutch) now see full English UI instead of raw key names in brackets.

• Fix treadle placement in weft header: Treadle 1 left/right setting now correctly flips columns in the weft/treadling display for both tieup and liftplan modes.

• Fix drawdown click crash: Prevent IndexOutOfRangeException when popup dismissal passes click to canvas outside data area.

• Fix stale tooltip after scrolling: Warp and weft header tooltips clear on scroll to prevent wrong pick/thread info showing.

• Fix QAT position: Quick Access Toolbar location (above/below) now persists across restarts.

• Suppress harmless bitmap layout race crash reports.

TempoWeave Studio v26.421.1

New Features

• Variegated Yarn Bleed: Space-dyed and self-striping yarns now support optional bleed at color boundaries, simulating how real dyes wick into each other. Enable via the Bleed checkbox in the variegation editor with a 0-50% slider.

• View Spacing: New option in View Cloth and Cloth Simulation to visualize gaps between threads based on yarn thickness, sett/beat density, and float length. Shows how open or dense your fabric will be.

• Variable Density (Cram and Dent): Set local EPI/PPI overrides on individual section markers for variable-density cloth. Sections with different densities render with proportional cell widths and spacing in View Cloth. Calculated EPI/PPI shown in Project Info when overrides are active.

• Show Sections toggle: Checkbox in the Window tab to show or hide section marker highlights. Sections always show when the Section Marker tool is active.

• Section marking thread count: Live thread/pick count displayed in the status bar while dragging to mark sections.

Improvements

• Print Threading: Fits 50 threads per row on A4/Letter portrait (was ~36). Rows end at even thread numbers. Last partial row is right-aligned to match the thread-1 edge of full rows above.

• Plot on Network: Warp and Weft dialogs now remember settings between opens during the same session (#182). Weft liftplan mode Pattern Preset B default changed to 3/1 left twill (#183).

• QAT position saved: Quick Access Toolbar location (above/below ribbon) now persists across restarts (#184).

Bug Fixes

• Fix Treadle Placement in weft header: Changing Treadle Placement (treadle 1 left vs right) now correctly flips treadle columns in the weft/treadling display, matching the tie-up canvas behavior.

• Fix drawdown click crash: Prevent IndexOutOfRangeException when a popup dismissal passes a click through to the drawdown canvas outside the data area.

• Fix stale tooltip after scrolling: Warp and weft header tooltips now clear when the view scrolls, preventing the wrong pick/thread info from showing after scrolling with a stationary cursor.

• Section Marker keyboard shortcut gated: M key now respects the license tier (Lite+), preventing bypass of the ribbon/menu disabled state.

• Suppress harmless crash reports from bitmap layout race condition during thumbnail loading.

TempoWeave Studio v26.415.3

New Features

• Section Marker now available to Lite and higher (previously Pro-only). Weavers use the Section Marker to mark sections of cloth for stepping through in Weave Assistant — for both dobby and non-dobby workflows. Section Assembly remains Pro-only.

• Chromebook installation guide added to the online docs under Linux. Covers Crostini setup, architecture detection, file sharing between ChromeOS and the Linux container, and known limitations.

Keyboard and Menu Improvements

• Fit to Window shortcut: Ctrl+0 on Windows and Linux, Cmd+0 on macOS

• Reset Zoom shortcut: Ctrl+1 on Windows and Linux, Cmd+1 on macOS

• Cut (Leave Space) shortcut: Ctrl+Shift+X on Windows and Linux, Cmd+Shift+X on macOS. Cuts the selection without collapsing the surrounding cells.

• New macOS menu entries: Fit to Window, Cut (Leave Space), Clear Selection (Esc), and Cycle Active Canvas (Tab)

Improvements

• Reset to Defaults button added to the Settings dialog

• Treadling Direction setting relabeled as Draft Style for clarity

Bug Fixes

• Section Marker keyboard shortcut (M) now respects the license tier. Previously the M shortcut bypassed the tier check that the ribbon button and menu item applied.

---

TempoWeave Studio v26.415.1

Bug Fixes

• Fix Weave Assistant cloth preview crashing repeatedly during rendering when the draft's cloth array was being resized

---

TempoWeave Studio v26.414.2

Improvements

• Fit to Window now uses fractional zoom for a more precise fit instead of rounding to the nearest integer zoom level

• Fractional zoom levels supported above gridSize 1 — smoother zoom transitions at low zoom levels where integer jumps are most noticeable

Bug Fixes

• Fix Print Drawdown hanging indefinitely on certain draft dimensions due to a floating-point rounding issue in the page layout loop

---

TempoWeave Studio v26.414.1

New Features

• Independent Treadling Direction: Treadling direction (Top to Bottom / Bottom to Top) is now an independent setting, separate from Draft Style and shed mode. Set your preferred treadling direction in Settings without changing your shed interpretation. Draft Style auto-switches it as a convenience, but you can override independently.

Improvements

• Fit to Window: Calculates the optimal zoom level to show the entire draft in the viewport. Zooms IN for small drafts and uses sub-1 zoom for very large drafts

• Zoom performance: "Weaving..." banner shows during zoom on large drafts so you know TempoWeave is working. Ctrl+scroll zoom is debounced — rapid scrolling only renders the final zoom level, skipping expensive intermediate renders

• Sub-1 zoom fix: Viewport culling now works correctly at sub-1 zoom — no more gaps between drawdown and weft header, and all threads render properly

Bug Fixes

• Fix WIF files saving incorrect color palette indices after palette changes (clear, replace, add yarn line). Other WIF readers (TempoWeave Classic, WeaveIt, iWeaveIt) now see the correct colors (#179, #180)

• Fix Section Assembly groups not updating thread counts, locations, and widths when threads are inserted or deleted (#175)

---

TempoWeave Studio v26.412.1

New Features

• Snapshot History: Save named version snapshots of your draft as you work. Stored inside the TWA file so they travel with the draft. Manual and automatic snapshots, restore in-place or open in new tab, thumbnails, rename, and clear history. Great for teaching workflows and tracking design evolution.

Improvements

• Zoom improvements: Zoom now preserves scroll position instead of jumping to thread 1. Smoother zoom with 70 levels (was 40). New Ctrl+scroll wheel zoom (Cmd+scroll on macOS). New Fit to Window button. Sub-1 zoom for seeing entire large drafts at a glance.

• Show Rulers: Horizontal ruler labels automatically skip numbers at low zoom to prevent collisions

• Image Center maximum rows increased from 999 to 9999

• Image Center preview panel hides gridlines when rows exceed 200 to show the pattern more clearly

• Section Assembly groups now update automatically when threads are inserted or deleted — thread counts, locations, and widths cascade through all parent groups (#175)

• TWA file format now preserves unknown entries on save for forward-compatibility with future versions

Bug Fixes

• Fix Color Swap and Color Exchange skipping weft colors in liftplan and multi-treadle mode: Color operations now work correctly in all draft modes

• Fix WIF browser and Snapshot History thumbnails rendered horizontally flipped compared to the drawdown view

• Fix crash when inserting threads or pasting beyond the warp/weft limit

• Fix Image Center crash when switching folders

• Fix tie-up paste crash when clipboard data exceeds the maximum tie-up size

TempoWeave Studio v26.409.1

New Features

• Compose Text in Image Center: render text as a weaving pattern with vertical, horizontal, or diagonal orientation. Supports font size, rotation, alignment, start column, and diagonal slant with line spacing

• Focus Mode hint: floating "Press F11 to exit Focus Mode" overlay appears briefly when entering Focus Mode (helps Windows/Linux users who have no native menu bar)

Improvements

• Common Weaves twills now support variable shaft counts (multiples of the ratio sum) with treadles fixed at the ratio sum. Tieup unit repeats correctly across all shaft blocks

• Common Weaves list reordered with Twill Family at the top

• Fixed Rosepath threading to use correct 1-2-3-4-1-4-3-2 pattern (was incorrectly using Point draw)

• Fixed Goose Eye threading to use correct 3x straight + 3x pair-swapped pattern

• Image Center maximum rows increased from 256 to 999

• Paste operations in weft/warp now scroll to show the start of the pasted region

Bug Fixes

• Fix Image Center crash when switching folders (thumbnail bitmap disposed while still bound to Image control)

• Fix tie-up paste crash when clipboard data exceeds TUArray bounds (IndexOutOfRangeException)

---

• Section Assembly tree expand state is preserved when editing sections or changing repeats

• Weaver's Writeup warns before closing with unapplied changes (Apply and Close / Discard / Cancel)

• Cloud sharing now supports larger draft files (up to 25 MB)

• Improved error messages when cloud upload fails

Bug Fixes

• Fix Section Assembly repeat count not refreshing group totals until manual refresh

• Fix Design Repeats on liftplan drafts causing weft to disappear

• Fix cloud share failing for drafts larger than 5 MB

• Fix Block Substitution predicted shafts and treadles showing incorrect values

• Fix Block Substitution panel splitter disappearing when dragged too far

• Fix Block Substitution panel losing data when undocked from main window

---

TempoWeave Studio v26.404.2

Improvements

• Added Emerald Green and Deep Orange to the LoftyFiber Euroflax yarn line in the built-in catalog

• Legacy macOS build: Check for Updates now shows a clear message directing users to tempoweave.com instead of silently failing

Bug Fixes

• Fixed Writeup template using target finished size instead of the calculated estimated finished dimensions

• Fixed crash when showing dialogs after closing the main window on macOS (window hidden but app still running)

• Fixed display backend initialization crash on some Windows 11 configurations (now shows troubleshooting steps)

---

TempoWeave Studio v26.402.4

Improvements

Bug Fixes

• Resolved an issue on some Macs where iCloud Drive could become temporarily unresponsive after launching TempoWeave

• Fixed WIF files created in other weave design software not displaying default thread colors correctly when only some threads had explicit color assignments

---

TempoWeave Studio v26.401.2

Improvements

• Interlacement rendering improvements: enhanced 3D thread depth with gap lines, shadow, and highlight for more realistic woven cloth appearance across Drawdown, View Cloth, and Cloth Sim

Bug Fixes

• Fix Double Cloth calculations: sett and beat now correctly double for all fold types (left, right, tubular)

• Fix finished estimated width now correctly doubles for folded double cloth (left and right fold)

---

TempoWeave Studio v26.401.1

New Features

• Left Origin support: new Origin Side setting (Right/Left) for European and Nordic draft conventions. Thread 1 can now appear on the left side of the draft with full pane layout swap

• Independent Shaft 1 Placement (At Top/At Bottom) and Treadle 1 Placement (On Left/On Right) settings, independent of Draft Style. Auto-switches when Draft Style changes, but can be manually overridden

• Thread Markers: blue cursor locator dots on warp, weft, and tieup grid edges to help identify the active row and column. Configurable in Settings

• Draft Style options renamed from American/Swedish to Top/Bottom for international clarity

• Color Palette capacity increased from 125 to 252 colors

• Add Color to Palette: right-click any swatch or empty palette area to add a color via color picker (works for all license tiers)

• Remove from Palette: right-click to remove unused colors from the WIF Palette

• Copy to Palette from Yarn Catalog now adds to existing palette instead of clearing it

Bug Fixes

• Fix paste operations (warp/weft threads and colors) not resolving palette index, causing Warp Winding Plan to show stale colors

• Fix Swedish draft extension area rendering in variable-width mode (extension now consistently at top)

• Fix selection rectangle Y positions in Swedish mode for weft canvas

• Fix pointer coordinate issues in tieup and weft canvases for left-origin mode (mouseup offset, selection drag)
