| 2025-05-30 | ExpressionParser: use correct operand order | Adrien Hopkins | |
| Most of the internal problems with the expression parser happened because I was accepting the arguments for binary operators in the wrong order. For example, '2 - 1' became '1 2 -', not '2 1 -'. The likely cause of this error is the following sequence of events: - In commit 6dbd32cd, I created the code for interpreting RPN. I accepted two arguments from the stack (o1 and o2), then performed o1 <op> o2. However, because stacks are in LIFO order, I should have actually done o2 <op> o1. - Later, in commit 94349688, I created the code for converting an infix expression to RPN. Creating the expressions in the correct order did not work, because my interpreter used the incorrect order. To 'fix' this problem, I created the expressions in the incorrect order. I did not notice any discrepancy, probably because I was not testing the individual methods, only the two-step whole (which found no errors). | |||

| 2025-04-30 | Add more UnitDatabase tests | Adrien Hopkins | |
| 2025-04-20 | Improve Metric base units SuppressWarnings message | Adrien Hopkins | |
| 2025-03-21 | Add tests for NameSymbol | Adrien Hopkins | |
| 2025-03-07 | convertToMulti: Compare unit bases to this.base | Adrien Hopkins | |
| This is a necessary precondition for the conversion methods used later on in convertToMutliple, and it is simpler than the existing method. I can also be sure it works, due to the tests I just wrote. | |||
| 2025-02-23 | Bump version number to 1.0.0b1v1.0.0b1 | Adrien Hopkins | |
| Compared to version 0.5.0, this release: - allows conversion to sums of units (e.g. 4/3 ft → 1 ft + 4 in) - allows non-integer exponents in expressions - adds the ability to change the UI language - gracefully handles datafile errors - adds more information to the loading-success message, and adds it to the About tab - allows the user to not use the default datafiles No new features will be added until the release of version 1.0.0. | |||
| 2024-08-28 | Bump version number to 1.0.0a1v1.0.0a1 | Adrien Hopkins | |
| 2024-08-22 | Show unit/dim file errors as popup | Adrien Hopkins | |
| Previously, any error in the unit or dimension file(s) crashes the program. Instead, 7Units now ignores any invalid lines, still parsing the correct ones, and shows a popup in case any errors happen. | |||
| 2024-08-22 | Add 1e-12 to unit sum parts before flooring | Adrien Hopkins | |
| This ensures that small errors from floor arithmetic will not, for example, cause 2 feet to be converted to 1 foot + 12 in. | |||

| 2024-03-23 | Add fractions using | to expressions | Adrien Hopkins | |
| | is like /, but with higher precedence. This feature is a part of GNU Units, and was included in 7Units for compatibility. | |||
| 2024-03-23 | Update documentation and version# (0.5.0a2)v0.5.0a2 | Adrien Hopkins | |
| 2024-03-23 | Complete exponentiation of dimensions | Adrien Hopkins | |
| Previously, you could only exponentiate individual dimensions in expressions. For example, `Length^3` was valid, but `(Length / Time)^2` was not. This is now fixed. | |||
| 2024-03-03 | Add + and - to prefixes | Adrien Hopkins | |
| This was added to be consistent with the data file spec, which was changed for consistency with unit expressions. It may not be a common expression, but it's a bit weird that you can use +/- in units but not prefixes, even though they're in the same file! | |||
