- Fixed an issue with "oct" clashing with the octal conversion function in an expression like "oct 1 2024 to jun 1 2025".

# Inline Knowledge Assistant
- The default provider for inline knowledge queries is now Wolfram|Alpha
- Wolfram|Alpha is the most reliable data source for live and accurate data, and it supports natural language queries.
- If Wolfram|Alpha cannot process your query (for example, if you use a language other than English), the knowledge assistant will direct your query to the latest AI model from OpenAI.
- The optional data subscription is required to use the inline knowledge assistant.

# Large currency notation
This update adds support for additional symbols representing large currencies (commonly used as shorthands in finance and journalism):
- Millions: $1M, $2m, or $3mn
- Billions: $1B, $2b, or $3bn
- Trillions: $1T, $2t, or $3tn

Currency results at these magnitudes will automatically use the new currency notation symbols.

- Which symbols are used depends on your region: for example, uppercase "$K, $M, $B, $T" are used in the US, and longer form "$k, $mn, $bn, $tn" are used in the UK.

# Minor improvements
- Fixed an issue with the automatic number formatter when formatting negative numbers with a fractional component after adding a space between the minus sign and number.
- New lines now automatically inherit the formatting settings of the previous line (this behaviour matches Soulver 2), rather than defaulting to the default.
- 'yr' and 'mo' are now supported as aliases for 'years' and 'months'.
- Support for "weather in place in a month of the year" style weather queries, like "weather in Tokyo in June" (advanced data subscription or Setapp required).

- A slightly more accurate definition for the density of corn.

# iPhone version
- Fixed an issue where the app could sometimes take a few seconds to launch during periods of low network coverage.
- Fixed an issue where the move to line start/end feature was moving the cursor to the line start/end (rather than paragraph start/end).

# Non-decimal bases
- Support for unit expressions in bases other than decimal, like "0xF days in minutes"
- Added support for base 8 (octal) numbers: 123 as octal (= 0o173)
- Added support for converting into other bases using a phrase "as base x", like "0b101101 as base 16" (= 0x2D)
- Added support for converting into other bases using functions: bin(), hex(), int() and oct() (inspired by Python)

# Expression Formatting

Auto-spacing division slashes:
- Soulver will now automatically insert spaces around slash division characters in certain cases, like in "500 / 40"
- There are still many cases where it's not preferred, like when working with fractions (1/3), rates (10 km/h), and Soulver will continue to not auto-space the division slash in these cases.

Thousands separators:
- Soulver will now delete unnecessary thousands separators when deleting digits from the end of a number (i.e. "1,000" will now become "100" when deleting the final zero)

# Financial Functions

Investment required for return
- This function is useful for when you have a specific return on investment you'd like to achieve from an investment (like a bank deposit)
- Specify a target dollar amount you wish you receive over a given period of time in interest, and the interest rate
- Soulver will tell you how large your initial bank deposit needs to be

Examples:
- "investment required for $10k/month at 5%" (= $2.4M)
- "deposit needed for $42k/year at 7.5%" (= $560k)

Daily mortgage payment functions:
- daily payment on $1M over 30 years at 6.5% (= $207.67)
- daily interest paid on $1M over 30 years at 6.5% (=$116.40)

# Other

- Fixed a bug where the floor() function wasn't working correctly with degree units (thanks Markus)
- Fixed an issue with very small numbers displaying as zero with notation disabled (thanks Eli)

# Rounding Numbers Up and Down to Nearest Interval
- Added phrases to round numbers up or down to a specific interval
- For example, "round 21 up to nearest 5" (= 25), "round down 20 to nearest 8" (= 16)

# Time to Decimal Conversions
- Support for converting time into decimal: for example, "10:15 to decimal" (= 10.25)

# Millisecond Unix Timestamps
- Added support for converting millisecond timestamps into dates, like "1733823083000 to date"

# Timezones
- You can now include "time" as a commenting word in time zone conversion, like "3pm Sydney time to Lisbon time"

- Fixed an issue with auto-converting quantities in brackets in QuickSoulver (thanks Chris)
- Fixed a crash with the factorial function (when doing an expression like "fact(9999999.3)")
- Fixed an issue where an expression like "1.6 fl oz/acre to mL/ha" would return an error instead of converting correctly
- An expression like "Monday 5pm-7pm" now correctly returns the interval of time specified (2 hours in this example)

# Localizations
- Minor improvements to the Russian localization
- Fixed an issue with the Chinese translation of Soulver not working correctly

# Larger Floating Number Pad with Accessory Bar (on iPad)
- We've added a larger floating number pad with increased key sizes to iPad and the handy accessory bar (which you may have used in the iOS version)
- The keyboard accessory bar provides many useful keys for various workflows, including currency conversions, working with variables, percentages, and date & time calculations
- You can customize the keyboard accessory bar with your own keys
- Toggle between the larger and compact floating number pads, depending on your needs

# Use the Floating Number Pad Without the System Keyboard (on iPad)
- It can be helpful to hide the system keyboard when you don't need it (especially on smaller iPads, like the iPad Mini in landscape)
- Hide/show the system keyboard using a button in the floating number pad

# Other Number Pad Improvements (on iOS)
- Added parentheses ( ) as a popup option on the multiplication key

- Fixed an issue where pasting copied text containing line reference tokens into other apps wasn't working (on iOS)
- Fixed an issue where the variable accessory keyboard could show an out-of-date variable state for a line (on iOS)
- Fixed an issue with sheets written in certain locales that use space as a thousands separator being incorrectly interpreted after syncing (thanks Øyvind & Edgar)

This update adds some improvements to the weather feature. They require the optional data services subscription, and iOS/iPadOS 18 or later.

Historical weather queries
-  Look up the average, high, and low temperatures, as well as rainfall, in a place on a particular date.
-  Data is available back to August 1, 2021.

Historical averages by month
-  Perform weather queries for the average high/low temperatures and rainfall in a place in a given month.
-  For example, "high in New York in June."
-  Note that these are historical averages based on weather records going back to the 1970s (not maximum/minimums).

Weather & time zone queries for small places:
-  Soulver can already perform weather and time zone queries for approximately 500 of the largest cities on Earth.
-  New in this update is the ability to look up weather for any place on Earth, including smaller places.
-  For example, you can now type "weather in Ubud, Bali," or "temperature in Assisi, Tuscany."
-  This feature also works for time zone queries using "time in (place)": "time in Inverness, Scotland," "time in Wollongong, NSW."
-  And when working out time differences: "time difference between Kemer, Turkey, and Mill Valley, Marin County."
