v3.10

Release 3.10 is a mix of new glyphs & glyph changes, and adjustments & fixes.

New glyphs:

• blackSquare (U+25A0)
• whiteSquare (U+25A1)
• whiteRoundedCornersSquare (U+25A2)
• lowerHalfWhiteSquare (U+2B12)
• topHalfWhiteSquare (U+2B13)

Other notable changes:

• Fixes alignment issue with otilde U+00F5. #191
• Improvements to contextual alternates (calt), primarily reducing the cases where case substitution is unwanted. #193
• Adjustments to the following whitespace glyphs: zerowidthspace, hairspace, thinspace, punctuationspace, enspace, emspace, sixthemspace, quarteremspace, thirdemspace and figurespace. #185
• Improvements to ogonek-based diacritics.
• Refinements and improvements to fractions (both dedicated glyphs and arbitrary frac parts)
• Kerning improvements to all weights
• Progress on mark and mkmk “dynamic diacritics”

All changes: v3.9...v3.10

Some new geometric glyphs:

Progress on mark and mkmk “dynamic diacritics”: (still work in progress)

Improvements to calt exceptions:

Fractions:

Whitespace:

v3.9

Fixes an issue with metadata where Medium, Semi Bold, and Extra Bold would incorrectly be marked as “italic” which would confuse certain software.

v3.8

• Possibly breaking change: Variable italic axis (really, slnt axis) has been inverted (negated) — a negative value causes the text to lean rightwards. This is only a breaking change if you are using the multi-axis variable font (Inter.var) and define slant angle using high-level CSS properties like font-style. This change was done to comply with the convention defined in the OpenType spec. #175 #172
• Variable font files are now significantly smaller thanks to #171 and #169
  • Inter.var.woff2 v3.7: 393kB, v3.8: 306kB
  • Inter-upright.var.woff2 v3.7: 267kB, v3.8: 224kB
  • All this while v3.8 introduces a whole new set of glyphs, kerning and feature code.
• Adds several new glyphs, like double-stemmed arrows and enclosed alphanumerics & symbols
  • Warning sign #168
  • Copyleft symbol #165
  • Really long arrows, useful in ligatures like --->
  • Arrows with double-lined stems, useful for “assign to”, with ligatures defined for some combinations with equals, e.g. =>
  • Enclosed glyphs in circles and squares
• Fixes a bug where U+0430 Cyrillic lower-case a would not be substituted for a single-storey “a” with cv11 enabled. #179
• Fixes a bug with slant of Ͽ (U+03FF) #170 #169
• Some calt code has moved to liga (standard ligatures), specifically arrow ligatures. Automatic case alignment is still kept in calt. So, you can now disable calt to disable only case alignment, and disable liga to only disable arrow ligatures.
• Improvements to kerning, spacing and letterform details
• Improved Microsoft Windows installation instructions #173

v3.7

• Fixes an issue with spacing to the right of capital "M"
• Improves positioning of various bullet glyphs
• Improved kerning
• new copyright glyph U+00A9
• new published (aka sound recording copyright) glyph U+2117
• new registered sign glyph U+00AE
• release now contains installation instructions for Linux

v3.6

• Fixes an issue related to ttfautohint where lower case "r" would be grid fitted incorrectly by ClearType on Microsoft Windows #119
• Fixes an issue with using case and calt features in combination where arrow combinations like -> would not be substituted by arrow glyphs #161
• Fixes an issue with rightArrow of bolder weights in italic #154
• Adjusts the glyph width of "bullet" to be exactly two "space" glyphs wide, allowing easy ad-hoc list creation with wrapping lines
• Improved kerning for a.1 (alternate single-storey "a")

v3.5

This is a very small incremental change from v3.4 that mainly contains improved metrics metadata for some macOS applications, improving vertical alignment.

See change log for v3.4 if you are upgrading from an earlier version.

v3.4

Inter UI is now called simply Inter, without the "UI" part.

• New name
• Lots of diacritic improvements
• Beta-grade light styles are now suffixed " BETA" to make it extra clear that these are in development
• Many many changes; several new glyphs, lots of redrawn glyphs, lots of kerning improvements, etc.

v3.2

• Now includes lighter weights ([100–400); which are of beta quality and needs testing)
• Lots of improvements to other weights (diacritics, glyph shapes, kerning, etc.)

This release is a big one in terms of source changes, adding up to 14,117 changed files with 714,886 additions and 259,287 deletions, since v3.1.

v3.1

Changes since v3.0

• Math operators have been improved (+ − × ÷ ± = ≠ ≈ ~ < > ≤ ≥)
• Lower-case "g" in heavier weights have been improved (lower arm made more rigid) #80
• Prime glyphs have been improved (′ ″ ‴ ⁗ ‵ ‶ ‷ ʹ ʺ) #86
• New alternate upper-case "i" with serifs, accessible through OpenType features ss02 and cv08 #89
• New alternate number three with flat top, accessible through OpenType features ss01 and cv09 #89
• Fixes an issue with the variable font where some type rasterizers would apply anti-aliasing as separate passes on each shape of a glyph, rather than drawing all shapes as one. This caused some edges to be slightly heavier than they should be. #85
• Some small improvements to kerning and other glyphs
