1.4.3

• Added 6 additional popular cryptocurrencies: Solana (SOL), Avalanche (AVAX), Terra (LUNA), Polkadot (DOT), Polygon (MATIC) and Shiba Inu (SHIB)
• Improved Simplified Chinese support
• Bug fixes

1.4.2

• Words in the form "utf-8" are now ignored
• For locales that use space as a thousand separator (like Russia), both , and . can be used as a decimal point
• Fixed an issue where an NSDecimalNumberOverflowException could be raised during parsing for very large numbers

1.4.1

• Support for natural language numbers: "five minus three", "five hundred thirty three + two hundred and twelve", "one year ago"
• Support for compounded natural phrase functions: "half of 30% of half of 100"
• Added an arbitrary base log function: "log 20 base 4"
• Added square root function: "square root of 81"
• Added cubed root function: "cubed root of 27"
• Scientific notation now works with numbers with fractions: "3e3.3"
• Scientific notation (rather than SI notation) is now used for numbers larger than a trillion, and smaller than 1e-9
• Certain date related words, and natural language numbers, are now ignored when not used as part of a calculation

1.4.0

• Possibly source breaking change: variables are no longer specified on an EngineCustomization, but rather on a Calculator or LineCollection directly
• A number of performance optimisations
• A number of minor bug fixes

1.3.1

• Added the ability to specify custom currency units in units other than USD
• Minor bug fixes and performance increases

1.3.0

• Added a metadata property on a TokenList. This API lets you quickly get to the data primitives involved in common expression "forms" (unit conversions, time zone conversions, etc).
• Support for hexadecimal and binary conversions ('0b1001 to decimal', '512 to hex', '0x23F to binary').
• Added a function to get the midpoint between two dates ('halfway/midpoint between March 12 and October 5')

1.2.1

• You can now specify the calendar and timezone for doing calculations on an EngineCustomization. Previous builds would always use the system timezone and calendar.
• Added the ability to set holidays on an EngineCustomization. These are taken into account when doing workday calculations.
• Support for noon/midday and midnight in time calculations
• Added a "seeksFutureDate" property on FeatureFlags. With this on, SoulverCore will optimize for a date result. For instance '11/3' will be 11 March (or 3 November, depending on the locale) rather than a division.
• Added a convenience method 'dateFor(expression)' on Calculator as a quick way to get a date from an expression.
• Improved Chinese (simplified) support

1.2.0

• Support for airports as timezones: '10pm SFO to LHR"
• Support for volume to weight cooking conversions: "1 cup butter in grams"
• Support for military time: "1945h + 30 mins"
• Support for 'misformatted' dates: "18.11 + 3 weeks"
• Bug fixes and minor performance improvements

1.1.7

• Fractions can now be used in all percentage word functions: "2/3 of 500", "50 is 1/5 of what", etc.
• Improved the behaviour of the "time unit until date" phrase when the time on the date is not specified:
  • Expressions with small units of time (like hours, minutes & seconds) will count up to the start of the requested date (like hours until tomorrow will count the number of hours until midnight tonight)
  • Expressions with larger units of time (like days, months, weeks, years) will count up to the same time on the requested date (so days until tomorrow = 1 day).
• Support for clock times without a colon when followed by a timezone: "1900 PST to UTC"
• Added a phrase for getting the ISO 8601 week number on a certain date: "week number on March 12", "week number today"
• You can now use fractional years in interest calculation functions
• Fixed an issue with applying a currency symbol to an expression in parenthesis
• 20% parsing performance increase

1.1.6

• More accurate conversions of US-customary fluid units
• Improvements to how certain date intervals are handled
• Bug fixes
