Version 1.4.8

Changes in this version:

• Add support for % for modulo as an alternative to mod. Since % is also used for percentages, the way the operator is interpreted depends on context: 5 % 2 or (348*34)%(293-1) is parsed as modulo, whereas 5% or 5% + 3 continues to be treated as a percentage.
• Add constants electron_mass, proton_mass and neutron_mass

Version 1.4.7

Changes in this version:

• Add Japanese units shaku, tsubo and tatami
• Significantly improve performance when calculating powers with decimal numbers, e.g. e^27.2
• Revamp fend's web UI: it is now built with React and runs calculations in a background thread. This fixes the timeout issues that used to affect long-running calculations.
• Fix a bug where variable serialisation could cause numbers to be negated. This only affected fend-wasm and fend-web but could lead to incorrect results when using variables across multiple calculations.
• Add some custom TypeScript definitions to fend-wasm

Version 1.4.6

Changes in this version:

• Add function mean (or average) to compute the mean value of probability distributions (by haykam821). For example:

  > mean(d6)
  7
  > average(1d20 + 5)
  15.5
  

• Add units nibble (4 bits) and U (rack units, equal to 1.75 inches)
• Serialised variables are now compatible between 32-bit and 64-bit platforms
• Fix bug where calculating very large roman numerals could crash the application

Version 1.4.5

Changes in this version:

• Add support for converting numbers to roman numerals (e.g. 45 to roman becomes XLV)
• Add ≠ as an alias for != (by @haykam821)
• Add <> as another alias for !=
• Update Windows MSI installer to WiX 4
• The fend Telegram bot now directly replies to messages, making it easier to use in group chats (by @frectonz)

Version 1.4.4

Changes in this version:

• Add == and != operators for equality and inequality (by @frectonz)

  For example:

  > 2 metres == 200 cm
  true
  > 4 kg == 2 lbs
  false
  

• The fend CLI now uses native-tls by default, instead of rustls. On Windows this uses SChannel (via the schannel crate), on macOS it uses Secure Transport via the security-framework crate, and on Linux it links to OpenSSL with the openssl crate. You can continue using rustls by compiling with the --no-default-features --features rustls flags. See the CLI's Cargo.toml for further details.

Version 1.4.3

Changes in this version:

• Add floor, ceil and round functions (by @frectonz)
• Add ¥ symbol for Japanese Yen (by @frectonz)
• Support power notation using Unicode superscript digits (e.g. 20²) (by @frectonz)

Version 1.4.2

Changes in this version:

• Add ability to convert codepoints to characters, e.g. 97 to character (by @mat-1)
• Fix horsepower value (by @probablykasper)
• Fix license files not being included in the workspace member packages (fend-core etc.) (by @albertlarsan68)

Version 1.4.1

Changes in this version:

• Fix bug where fend could return incorrect results when calculating exponents or roots of certain units, e.g. sqrt(milli).

Version 1.4.0

Changes in this version:

• The license of fend has changed. As of v1.4.0, fend is available under the GPL 3.0 (or later). See LICENSE.md for more information.

• Change unit simplification and unit aliasing to be simpler and more consistent. Units like % and million are now simplified unless you explicitly convert your result to one of those units. fend will now also simplify certain combinations of units, such as volts / ohms becoming amperes.

  For example:

  > 5%
  0.05
  > 46 million
  46000000
  > 0.5 to %
  50%
  > 34820000 to million
  34.82 million
  > (5 volts) / (2 ohms)
  2.5 amperes
  > 3 feet * 125 kg * s^-2
  114.3 newtons
  > c / (145MHz)
  approx. 2.0675341931 meters
  

• Rename Windows installer artifacts (MSI files) to also include the version number, e.g. fend-1.4.0-windows-x64.msi.

• Replace nanorand dependency with rand, which is better supported and fixes compilation errors on FreeBSD.

Version 1.3.3

Changes in this version:

• Add pkgx package (by @michaelessiet)
• Add x86_64-unknown-linux-musl binary
• Fix terminal issues on some architectures such as MIPS (by @eatradish)
