What’s new in Numlex

This is a packaging-only patch release. The app is unchanged from 4.9.0; the
DMG is back to the classic, standard disk image.

What changed

• The installer image no longer carries styled artwork, a custom background,
  window layout or a volume icon. Numlex-4.9.1-macOS-arm64.dmg is a plain,
  read-only disk image containing exactly two items: Numlex.app and an
  Applications shortcut. Open it, drag the app across, eject.
• Everything else — every feature, calculation, dataset and setting — is
  identical to 4.9.0.

Where the styling came from

4.9.0 introduced an optional Finder-styled DMG (custom background and icon
positions) produced by an automation pipeline. It proved to be more fragile and
less predictable than the plain image, so this release removes that pipeline and
its artwork entirely. The plain image is now the only default: there is no style
flag, no "-plain" filename variant, and no generated background.

Unchanged in this release

• One-time welcome (calculation bloom), dates & times, durations, timezones,
  timestamps, Timespan, video timecode, work calendars and special dates.
• Finance: compound interest, ROI/CAGR, present value, loans, sales tax/VAT/GST
  presets, 2026 income-tax estimates (estimates only, not tax advice) and
  BLS CPI-U inflation.
• PDF export and native printing from one frozen snapshot.
• Tags, dividers, subtotals, grand totals, tag aggregates and statistics
  (including the dynamic rand epoch and the footer statistic).
• 27 built-in functions and the adaptive floating Total.

4.9.0 is untouched

The 4.9.0 GitHub release, its tag, its notes and its assets remain exactly as
published; nothing was replaced, edited or re-uploaded. 4.9.1 is a new, separate
release. Updater-enabled builds (4.8.0 and later) simply see 4.9.1 as the next
version in the app.

Updates

Secure in-app updates are unchanged: HTTPS-only feed, EdDSA-signed archives
verified before extraction, Sparkle 2.9.6. 4.8.0 was the first updater-enabled
release, so 4.8.x and 4.9.0 users receive 4.9.1 in the app; users on 4.7.0 or
earlier install this release manually once from the .dmg and update in-app
afterwards.

Installation

• macOS 26 or later, Apple Silicon (arm64).
• Download Numlex-4.9.1-macOS-arm64.dmg, open the plain disk image and drag
  Numlex.app into Applications.
• The app is ad-hoc signed and not notarized (a deliberate choice for this
  project). On first launch, Control-click the app and choose Open, or allow
  it under System Settings → Privacy & Security → "Open Anyway".
• Verify the download:
  shasum -a 256 -c SHA256SUMS and compare against the release page.

This is the largest Numlex release yet: a one-time welcome, a complete date and
time suite, finance calculations, PDF export and printing, and a plain-text
structure for tags, subtotals and statistics. Everything stays local, strict and
offline where the data allows it.

First launch

• A genuinely new install opens on a one-time native calculation bloom: ten
  real calculations in the app's own editor palette gather around the app icon,
  settle into the official slogan, and end with a single Get Started button.
• With Reduce Motion the final screen is shown immediately, with no staged
  animation, and the notebook is usable right away.
• Existing installs are never re-onboarded: any prior store, rate cache, weather
  cache or location cache counts as an existing install, so upgrades go straight
  to the notebook.
• The welcome sequence runs once per install. It is not a re-runnable feature.

Dates and times

• Calendar arithmetic on plain month names, with today / tomorrow /
  yesterday and compound periods such as March 12 + 3 weeks 2 days.
• Compound duration literals (1 h 45 min, 1 day 2 hours 30 min), natural
  duration display, and duration-aware section and footer totals.
• Clock arithmetic and laptime: 3:30pm + 2 hours 15 minutes,
  7:30am to 8:45pm, 3:30pm as laptime.
• Timezones on a bundled, hash-verified offline catalog: time in Paris,
  2am PST to GMT, 6pm Sydney in Chicago, time differences, plus custom
  aliases under Settings → Dates & Times.
• Timestamps and ISO 8601 in both directions, including the documented
  millisecond threshold and strict errors for invalid or DST-gap values.
• Timespan notation for time-dimension results, globally, per answer, or with
  an explicit as timespan.
• Video timecode and frames: 03:10:20:05 at 30 fps + 50 frames,
  30 fps × 3 minutes, 15.6k frames / 24 fps.
• Work calendars: workday and business-day queries, hours per workday, and
  public-holiday data for 25 countries from 2019 to 2035, bundled offline and
  failing closed outside its coverage.
• Special dates: Easter (Gregorian computus), Christmas, and days until ….

Units and wording

• Spelled per rates, derived units, safe speed aliases, and a source-aware
  ms target, so unit phrases read naturally without changing existing forms.

Money and finance

• Compound interest and investment phrases, ROI, annualized ROI / CAGR, and
  present value.
• Loans and mortgages: payment, principal, interest and total paid, with the
  documented average-per-period convention.
• Configured sales tax / VAT / GST from versioned, hash-verified presets, with
  the documented "unset vs manual 0%" distinction for the United States.
• Estimated 2026 income tax for ten countries (US, GB, AU, CA, DE, FR, NL, IN,
  RU, JP) from official 2026 schedules. These are coarse national estimates for
  a single individual — not tax advice — and the app documents each table's
  approximations and excludes state/provincial taxes, credits and contributions.
• BLS CPI-U inflation: continuous 1913–2025 annual data plus a provisional 2026
  point and an explicit-rate future form, all offline and versioned.
• Currency operands keep the existing strict money rules; a missing rate pair is
  always the explicit "Rates unavailable" state.

Tags, subtotals and statistics

• A trailing #tag marks rows for total of #tag, average of #tag,
  count of #tag and median of #tag.
• An exact --- divider starts a new section; subtotal (optionally with a
  percentage or a name) sums the current section, and grand total sums the
  successful subtotals — a failed or overflowed subtotal never counts.
• Add Subtotal (⌘T) and Add Grand Total (⌘⇧T) insert commands into a
  blank or strict empty-assignment line; double-clicking an empty answer row does
  the same; Convert to Normal Line turns a subtotal row into a plain number.
• New functions: count, median, sample stdev (n−1) and rand, alongside
  the natural forms median of …, count of …, standard deviation of … and
  random number between X and Y.
• rand is execution-aware dynamic: stable within its epoch, rerolled by a
  semantic edit or Recalculate Dynamic Values (⌘R), copyable but never
  tokenizable and never part of the Previous Answer chain. PDF export freezes
  the current epoch.

Footer Total

• Right-click the floating Total to choose Sum, Average, Count or
  Median; the choice is app-global and persisted, and derived aggregate rows
  never contribute.
• The Total bubble hides its label and gap when width is tight while the footer
  geometry stays stable.

PDF export and printing

• File → Export Sheet as PDF… and File → Print… (⌘P) render one
  immutable snapshot of the evaluated sheet through one deterministic paginated
  renderer — the live editor, caret, selection, highlights and tokens are never
  touched.
• Session-only options: font family, face and size; syntax highlighting; the
  original source line numbers; the footer Total; hiding // comments and
  leading # markers; and an inclusive line range.
• Answer tokens keep their real capsule labels, highlights are preserved, rows
  wrap safely, and the exported footer uses the current footer statistic over
  the exported rows only.
• Writes are atomic, an empty range disables the action with an explanation, and
  the whole path is fully offline.

Functions

• The shared registry now has 27 built-in functions, including the new
  count, median, stdev (sample) and rand, with the same strict call,
  arity and domain rules as before.

Updates

Secure in-app updates are unchanged: HTTPS-only feed, EdDSA-signed archives
verified before extraction, Sparkle 2.9.6, and the automatic-check preference
owned by Sparkle itself. 4.8.0 was the first updater-enabled release, so 4.8.x
users receive 4.9.0 in the app; users on 4.7.0 or earlier install this release
manually once from the .dmg and update in-app afterwards.

Privacy

Numlex is local-first. Sheets and settings stay in
~/Library/Application Support/Numlex; the timezone, holiday, sales-tax,
income-tax and CPI datasets are bundled, versioned and hash-verified; PDF export,
printing and (where possible) every calculation work offline. The network surface
remains the explicit allowlist: the hourly currency-rate refresh, weather in …
lookups you type, and place lookups for geography lines. No analytics, no GPS and
no cloud sync.

Installation

• macOS 26 or later, Apple Silicon (arm64).
• Download Numlex-4.9.0-macOS-arm64.dmg, open it and drag Numlex.app into
  Applications.
• The app is ad-hoc signed and not notarized (a deliberate choice for this
  project). On first launch, Control-click the app and choose Open, or allow
  it under System Settings → Privacy & Security → "Open Anyway".
• Verify the download:
  shasum -a 256 -c SHA256SUMS and compare against the release page.

Auto appearance and the Dark app icon are now the fresh-install defaults, and the
Settings window has been redesigned into a compact, tidy layout.

Fresh-install defaults

• Auto appearance is the default for new installs. A fresh Numlex follows the
  macOS appearance live from the first launch: Light, Dark or an automatic switch
  mid-session all flow into the window chrome, native menus, the answer palettes and
  the editor. Light and Dark remain one-click choices, and existing installs are
  never changed — a stored appearance (Light, Dark or Auto) is honoured exactly,
  and stores predating the Auto choice keep their established Light behavior.
• The modern Dark app icon is the default. The Dock and App Switcher show the
  signed bundle's Liquid Glass primary icon; the optional Light icon is one click
  away in Settings and both choices come from the same compiled catalog (identical
  geometry and rendition ladder), so switching never resizes or softens the tile.

Settings redesign

• The category navigation is a compact, centered row of icon-over-label tiles
  under the titlebar — no sidebar and no full-width tab bar. The selected tile is a
  calm neutral surface with an accent-colored icon and label.
• The window is narrower, and pages now use the available width: the cards reach the
  window edges instead of leaving wide empty fields, and every page starts with its
  first group.
• General gathers the Interface language, appearance and application icon in one
  aligned group, with the icon chooser as a normal trailing control.
• Obvious captions were removed, and the custom number-format field is now a real,
  always-visible text field with a #,##0.00 placeholder before you type.
• About shows the current app icon, the runtime version and two links
  (Documentation and GitHub) above the update controls.

Updates

Secure in-app updates are unchanged: HTTPS-only feed, EdDSA-signed archives verified
before extraction, Sparkle 2.9.6, and the automatic-check preference owned by
Sparkle itself. 4.8.0 was the first updater-enabled release; users on 4.7.0 or
earlier install this release manually once from the .dmg and update in-app
afterwards.

Installation

• macOS 26 or later, Apple Silicon (arm64).
• Download Numlex-4.8.2-macOS-arm64.dmg, open it and drag Numlex.app into
  Applications.
• The app is ad-hoc signed and not notarized (a deliberate choice for this
  project). On first launch, Control-click the app and choose Open, or allow it
  under System Settings → Privacy & Security → "Open Anyway".
• Verify the download:
  shasum -a 256 -c SHA256SUMS and compare against the release page.

Currency arithmetic, a dimension-agnostic Total bar, and the Tahoe sidebar glass fix.

Currency arithmetic

• ISO codes are case-insensitive. 500 usd, 500 Usd and 500 USD all mean
  500 US dollars (any of the 166 supported ISO codes).
• Cross-currency + and -. A line may combine currencies: the first money
  operand sets the result currency and every other operand is converted into it
  with the current rates. With 1 EUR = 1.1 USD, 500 usd - 300 eur is 500 − 300/1.1
  = $227.27. Symbols and codes mix ($500 - 300 eur, 500 usd - €300), and the
  same rule applies to named values and live answer tokens.
• Scalar and percentage operands keep their meaning (500 usd - 20 = $480.00,
  500 usd - 10% = $450.00), and assignments record money
  (balance = 500 usd - 300 eur stores US dollars).
• Rejected safely: currency × currency and currency ÷ currency stay errors
  (never a silent squared currency); physical units still never convert implicitly.
• Missing rates produce the explicit Rates unavailable answer — never a
  guessed number, a partial sum or a stale rate.

Total bar

The persistent bottom Total panel now sums every ordinary scalar answer:
unitless numbers, unit-bearing quantities (2 kg), money, named values and exact
integers. It stays deliberately dimension-agnostic — one plain unitless number,
with no conversion between rows, no FX normalization and no unit suffix
(2 kg, $3 and 4 EUR total 9) — and inline total section commands are
unchanged and still excluded from it, so the two never double-count.

Sidebar glass on macOS 26 (Tahoe)

The New Sheet button, the selected sheet row and the active folder tab could render
as a near-solid gray surface on the new Liquid Glass renderer: an alpha-bearing
dynamic color was handed to Glass.tint, whose alpha the renderer reads as tint
strength. All sidebar surfaces now render through one shared primitive — a
deterministic wash drawn by a normal fill under one untinted Liquid Glass layer,
with a single boundary stroke — so the surfaces stay light in Light Appearance and
calm in Dark Appearance, with the same radii, hover, rename and drag-and-drop
behavior.

Install and update

• macOS 26 or later, Apple Silicon (arm64).
• Ad-hoc signed and not notarized. On first launch, Control-click (or
  right-click) Numlex.app, choose Open, and confirm the prompt.
• Installing: open the .dmg and drag Numlex.app into Applications.
• Updating: 4.8.0 and later update in the app (Numlex → Check for Updates…, or
  automatically). 4.7.0 and earlier have no updater — install 4.8.1 manually
  once, then update in the app.

Secure in-app updates, the full per-answer formatting system, custom syntax
colors, persistent line highlights, a reclaimed line-number gutter, and a
complete documentation set.

Secure in-app updates

• Check for Updates… in the Numlex menu (directly under About) and in
  Settings → General → Updates, plus an Automatically check for
  updates switch. Both use Sparkle's standard update, install and relaunch
  interface — no custom updater window.
• Updates are fetched over HTTPS from https://numlex.tech/appcast.xml
  and every archive is signed with EdDSA (Ed25519); with
  SUVerifyUpdateBeforeExtraction the signature is verified before the
  archive is extracted. A tampered or corrupted download is rejected.
• The automatic-check preference is Sparkle's own; anonymous system profiling
  is disabled, and no identifiers, analytics or usage data are sent. The
  updater makes two kinds of HTTPS request: the feed, and the version-pinned
  release asset when an update is accepted.
• Numlex 4.8.0 is distributed ad-hoc signed and not notarized — unchanged
  from previous releases. Updates are accepted through the mandatory EdDSA
  route; the matching Apple-identity route is an alternate Sparkle trust path
  and is not required when the EdDSA signature validates.

Formatting and appearance

• Result display modes — Automatic, Decimal, Scientific, Engineering,
  Fraction and Custom patterns (#,##0.00, quoted literals, Indian-style
  grouping #,##,##0, %/‰ scalers, ¤ currency placeholder, exponents).
  Invalid patterns are saved but never rendered; the answer falls back to
  Automatic.
• Answer context menu — right-click (or Control-click) an answer for
  Copy Answer, the rounding slider on eligible numeric answers (0…10 dp,
  independent of the global rounding), Number Format, a conditional
  Reset Formatting to Defaults, and Delete Line. The menu exists only
  for answers that have one. Overrides are display-only: values, tokens,
  totals and dependencies never change.
• Persistent line highlights — six colors plus None, applied from the app
  menu Format → Highlight or the editor's text context menu to the caret's
  line or the selected lines (lines without answers included). A highlight is
  attached to a line's stable identity so it survives insertions above, saved
  with the sheet, and sanitized on load.
• Answer-column styling — Leading/Trailing alignment and five surfaces
  (Neutral, Sand, Slate, Sage, Blush); the answer text stays high-contrast on
  every choice.
• Custom syntax colors — eight roles (Numbers, Operators, Variables,
  Units, Specifiers, Headings, Comments, Labels), preset swatches or an
  arbitrary opaque sRGB color from the system picker, per-role Default and
  a Reset Syntax Colors action, with a live preview.
• Reclaimed line-number gutter — hiding line numbers now restores the full
  18 pt text inset (54 pt with numbers, 18 pt without).
• Global rounding (2…10 dp) and the regional number formats stay on the
  Numbers tab; the default answer format is applied globally unless a specific
  answer overrides it.

Documentation

• New complete syntax reference covering every construct: line forms,
  numbers and bases, operators, all 23 built-in functions, percentages, money,
  total, dates, units and the full non-currency unit catalog, currencies,
  network queries, regional formats, result display, answer tokens, constants
  and a keyword index.
• New Settings & appearance reference for all five tabs and every
  formatting/appearance contract.
• New Updates reference describing the trust chain, endpoints, privacy and
  the release workflow.
• The documentation site (English, searchable) lives at
  https://numlex.tech/docs/.

Install

• macOS 26 or later, Apple Silicon (arm64).

• Download Numlex-4.8.0-macOS-arm64.dmg, open it and drag Numlex.app into
  Applications.

• Numlex is ad-hoc signed and not notarized: on first launch, Control-click
  (or right-click) Numlex.app, choose Open, and confirm the prompt.

• Verify the download with the checksums file from the same release:

  shasum -a 256 -c SHA256SUMS

• Homebrew: brew install --cask Qulierm/tap/numlex (the cask now sets
  auto_updates true, because 4.8.0 updates itself).

Updating from an older version

• 4.7.0 and earlier have no updater: install 4.8.0 manually once, exactly
  as above.
• 4.8.0 and later update from inside the app.

What's new since 4.6.0

Typed booleans and comparisons — true/false values, the and, or and not operators, x == y style comparisons, and lazy if … then … else conditions; boolean lines stay distinct from number lines and mix with numbers only where explicitly defined. (xor is an integer/bitwise operator, not a boolean one.)

Advanced percentages — percentage change between two values, reverse percentages ("what is X as a share of Y"), of / on / off percentage phrases, percentage ratios, fraction ↔ percentage conversion, and 1.5x-style multipliers.

Quantity and unit arithmetic — quantities with units calculate like ordinary numbers: 2 kg + 500 g, 3 mi to km, 100 ml per 5 g, rates and price-per-unit ($4.99 for 500 g → per kg), plus user-defined custom units (up to 100, stored with the app), pixels/PPI conversions and cooking density helpers (volumes ↔ weights through a built-in ingredient table).

Exact integer math — base literals and converters (0x1F, 0b1101, 0o17, hex(255), bin(x), as base 16) with exact 64-bit integer results, and bitwise operators: &, |, xor, <<, >> (with and/or word forms on integer lines). Radix answers copy exactly what they show, and radix literals are never rewritten by input formatting.

Coordinates and local distance — decimal-degree and DMS angle lines (156.742°, 156° 44′ 31″), coordinate validation, and Haversine distances between explicit coordinates — all computed locally. Place names in location of …, latitude of … and distance between … and … lines are geocoded with the free Open-Meteo geocoding API; results are cached in the app's data folder for 30 days. Privacy: Numlex never uses GPS or location access, needs no API key, and sends only the explicit place names you type to Open-Meteo geocoding.

Requirements

macOS 26 or later, Apple Silicon. The app is ad-hoc signed and not notarized: on first launch, Control-click (or right-click) Numlex.app, choose Open, and confirm the prompt.

What's new since 4.5.1

Modern app icon — rebuilt with the Icon Composer pipeline (Assets.car-based, system-native rendering in the Dock and Finder).

Regional number settings — per-region presets with grouping and compact-notation controls, opt-in paste conversion, and full decimal-comma / semicolon-region support; numeric formatting stays independent of the interface language.

Reorganized Settings — five compact native tabs (General, Editing, Numbers, Constants, Styling) with native switches and live previews.

Restrained motion — answers fade in when a result appears, values crossfade on change, and token bubbles get a short settle; all self-terminating and disabled under System Reduce Motion.

Reliable answer tokens — double-click insertion works on freshly created and switched sheets (previous versions dropped roughly half of the clicks), and a stationary multi-click run mints exactly one bubble per click pair.

Same-line answer clicks — double-clicking an answer while the caret sits on that same line now places the bubble on a new line directly below the source, instead of doing nothing.

Optional Total bar — a new "Show total bar" setting (General → Notebook) hides the sheet's bottom Total panel; inline total lines are unaffected.

Requirements

macOS 26 or later, Apple Silicon. The app is ad-hoc signed and not notarized: on first launch, Control-click (or right-click) Numlex.app, choose Open, and confirm the prompt.

Numlex 4.5.1 is a patch release that restores answer double-click tokens.

What's fixed

• Answer double-click tokens: in 4.5.0, double-clicking an answer minted no
  token once the window had been resized — the answer column's AppKit hit
  surface kept a stale frame while the SwiftUI layout reflowed. The hit
  surface is now kept in sync on every layout pass, so double-tap minting,
  right-click answer menus and wheel scrolling work at any window size.

Everything from 4.5.0 is included: section totals, the compact window,
keyboard-only sidebar reopening, and the answer menu.

Install

• DMG: download from this release and drag Numlex.app into Applications.
• Homebrew: brew install --cask Qulierm/tap/numlex (the project's custom
  tap, not the official Homebrew cask repo).

Requirements and signing

• macOS 26 or later, Apple Silicon (arm64).
• Numlex is ad-hoc signed and not notarized. On first launch, Control-click
  (or right-click) Numlex.app, choose Open, and confirm the prompt.
• Verify the download with the SHA256SUMS file from this release.

Numlex is available under the MIT License.

What's New in Numlex 4.5.0

• Section totals: a standalone total line sums the eligible unitless
  calculation answers since the sheet start or the previous total, then
  resets the section. The answer renders semibold under a gray rule placed
  exactly between the neighboring answers. Live Copy, per-answer rounding
  and answer tokens all work on totals, and wrapped logical lines keep
  their gutter number centered on the block.
• Compact main window: the content height now goes down to 260pt for small
  desks. The default remains 800×600, and the sidebar and answers keep
  scrolling safely at any height.
• Keyboard-only sidebar reopening option: a Settings toggle (off by
  default) hides the native sidebar button once the sidebar is collapsed.
  Reopen any time with ⌃⌘S (Control-Command-S) or View > Toggle Sidebar —
  the button returns with the sidebar. Fully backward compatible.

Privacy

Sheets stay local in Application Support. The only network traffic is the
background currency-rates refresh plus Open-Meteo lookups for weather in … lines you type yourself — only the city you typed is ever sent,
never GPS or location data.

What's new

• Broad math functions and ^. The engine now has a shared pure function registry across every scalar path — sqrt, abs, round(x) / round(x, d), variadic min/max/sum/average, pow (same contract as the ^ operator), ln/log/log10, radians-based sin/cos/tan with asin/acos/atan, and radians/degrees helpers. Names are case-insensitive, arguments are full nestable expressions, and anything malformed is a precise error, never a guess.
• Native answer menu. Right-click (or Control-click) any answer: Copy Answer copies the exact displayed value, a discrete 0…10 dp slider re-rounds just that answer without touching the source, and Delete Line removes the source line. Fully native menu, at home in Light and Dark.
• Natural named-money multiplication. apple = 5$ prices one apple, and 2 apples + 3 apples totals in dollars — money names work with the same strict grammar as everything else.
• Current weather: weather in <city>. Type weather in London for the live 2 m temperature in Celsius degrees (C°), resolved through Open-Meteo with no API key. Lookups are cached for ten minutes and the last good reading keeps serving while offline; the city name is highlighted exactly like a measurement unit.
• Sidebar contrast and divider refinements. The folder-tab strip and pane divider were retuned for a calmer, more legible sidebar in both appearances.
• Refreshed product README. The feature tour now covers functions, the answer menu, named money and weather, and the engine suite stands at 663 shared cases.

Requirements & install

• macOS 26 or later, Apple Silicon (arm64).
• Ad-hoc signed, not notarized (no Developer ID). Drag Numlex.app into Applications; on first launch, Control-click (or right-click) the app and choose Open to bypass the Gatekeeper warning.
• Verify the download: shasum -a 256 -c SHA256SUMS (checksum file is a release asset).
• Privacy: weather sends only the city you typed to Open-Meteo (weather in London sends London). No GPS, no location permission, no API key.

What's new

• Folder tabs in the sidebar. The sidebar bottom now has one level of folder tabs that filter the sheet list — General shows unfiled sheets, and each folder shows its own. Sheets can be created, renamed, deleted, and moved between folders (drag a sheet onto a tab); the layout is persisted and the tab strip adapts when it overflows. Folders are a single flat level (no nesting).
• Answer Tokens at the cursor. Double-clicking an answer bubble inserts a token at the editor's live caret, or replaces the current selection — it never appends on a new line. Tokens keep stable references and preserve scroll and caret, and the source identity is the clicked answer's line.
• Reusable answer sources. The same answer line can back any number of distinct tokens; each bubble keeps its own live identity, and rapid repeated double-click pairs each insert one token.
• Refined sidebar. Folder-tab geometry, hover behavior, and hidden scrollers were tuned so the sheet list scrolls smoothly without a visible sidebar scrollbar.

Requirements & install

• macOS 26 or later, Apple Silicon (arm64).
• Ad-hoc signed, not notarized (no Developer ID). Drag Numlex.app into Applications; on first launch, Control-click (or right-click) the app and choose Open to bypass the Gatekeeper warning.
• Verify the download: shasum -a 256 -c SHA256SUMS (checksum file is a release asset).

What's new

• Light and Dark themes. Settings → General now has a persisted Light/Dark appearance switch. Light uses an independent light palette and Dark restores the original dark palette. The choice applies live to windows, menus, the glass chrome, text rendering and the live preview, and is kept across launches.
• Hover-highlighted source answers. Hovering an answer token outlines its stable linked source answer — only for active tokens, and the identity survives source lines being moved or wrapped.

Requirements & install

• macOS 26 or later, Apple Silicon (arm64).
• Ad-hoc signed, not notarized (no Developer ID). Drag Numlex.app into Applications; on first launch, Control-click (or right-click) the app and choose Open to bypass the Gatekeeper warning.
• Verify the download: shasum -a 256 -c SHA256SUMS (checksum file is a release asset).

What's new

• Global custom constants. Settings → Constants: up to 100 user-defined named values — scalar formulas (PI = 3.141592653589793), percentages (Tax = 20%) and single-fiat money (Monthly Rent = $2,500). Constants can reference each other in any row order, with per-row dependency and cycle validation, live status per row, and a strict resolver shared by every evaluator, token, previous-answer, auto-titling and syntax-highlighting path. New rows get valid generated names (constant, constant_2, …).
• Expanded currencies and conversions. 166 live fiat currency codes with safe output symbols and English names, plus ~290 measurement units across length, area, volume, mass, time, speed, pressure, force, torque, energy, power, flow, viscosity and engineering units.
• Visible New Sheet list animation. Creating a sheet now animates its insertion in the sidebar.
• Compact Settings window. The Settings window opens at a compact 720×460 with a constrained resize range; every tab (General, Constants, Styling) fits without scrolling.

Notes: .nlx exports never embed global constants — they travel with the app settings only. Constant values intentionally do not support unit-bearing expressions (use the conversion grammar in sheets for those).

Requirements & install

• macOS 26 or later, Apple Silicon (arm64).
• Ad-hoc signed, not notarized (no Developer ID). Drag Numlex.app into Applications; on first launch, Control-click (or right-click) the app and choose Open to bypass the Gatekeeper warning.
• Verify the download: shasum -a 256 -c SHA256SUMS (checksum file is a release asset).

A complete native rewrite for macOS: SwiftUI with the Liquid Glass design language, replacing the legacy Electron app.

What's new

• Native SwiftUI / AppKit macOS app (macOS 26, Apple Silicon)
• Notebook calculations: numbers, variables and name = expression assignments, percent, powers, dates
• Unit conversions (10 km to meter, 100 C to F) and currency conversions (USD/EUR/RUB) with live rates
• Live answer references — clickable result tokens that trace back to their source lines
• Styling: per-role syntax colors (numbers, operators, variables, units, specifiers, headings, comments, labels), font size/family, input helpers
• Native sheet management with .nlx import/export
• Localized interface (en, ru, de, it, fr, zh)

Requirements

• macOS 26 or later
• Apple Silicon (arm64)
