- * Migrate from `yarn` to [`pnpm`](https://pnpm.io/)
- * Update dependencies

 ## [3.0.0](https://github.com/cshaa/filtrex/releases/tag/v3.0.0)
+
 ### Breaking Changes
- * Trying to access properties that aren't present in the `data` object now produces an error ([#22](https://github.com/cshaa/filtrex/issues/22))
- * Logical values are no longer converted to `1` and `0`, proper booleans are returned instead ([#27](https://github.com/cshaa/filtrex/issues/27))
- * Corrected the precedence of exponentiation ([#41](https://github.com/cshaa/filtrex/issues/41), [#43](https://github.com/cshaa/filtrex/issues/43))
- * Modulo now always returns a positive number ([#36](https://github.com/cshaa/filtrex/issues/36))
- * Removed `random` from standard functions ([#47](https://github.com/cshaa/filtrex/issues/47))
- * Corrected the precedence of `not in` ([#42](https://github.com/cshaa/filtrex/issues/42))
- * Corrected the precedence of the ternary operator ([#34](https://github.com/cshaa/filtrex/issues/34#issuecomment-866426918))
-
- ### Deprecations
- * The ternary operator `? :` is now deprecated in favor of `if..then..else` ([#34](https://github.com/cshaa/filtrex/issues/34))
- * Modulo operator `%` is now deprecated in favor of `mod` ([#48](https://github.com/cshaa/filtrex/issues/48))

 ### New Features
- * Chained comparisons are now possible: `x>y>z`, meaning `x>y and y>z` ([#37](https://github.com/cshaa/filtrex/issues/37))
 
- * Operators can now be overloaded using `options.operators['+']` and the like ([#38](https://github.com/cshaa/filtrex/issues/30))
-   * The supported operators are `+`, `-`, `*`, `/`, `mod`, `^`, `==`, `!=`, `<`, `<=`, `>=`, `>`, `~=`
-   * The minus operator overload is used for both the binary and the unary operator:
-     * `-a` will result in `operators['-'](a)`
-     * `a - b` will result in `operators['-'](a, b)`.

- * Adds `options.constants`, which allows you to pass constant values (like pi) to the user without the need to modify `data` ([#38](https://github.com/cshaa/filtrex/issues/38))
-   * When using unquoted symbols, constants shadow data properties, ie. `2*pi` will resolve as `2*constants.pi` if it is defined

 ## [2.0.0](https://github.com/cshaa/filtrex/releases/tag/v2.0.0)
 
- * **BREAKING CHANGE**: Changes the `compileExpression` method's call signature
-   * Previously the method had up to three parameters: `expression`, `extraFunctions` and `customProp`
-   * Now the method has two parameters: `expression` and `options`, where `options = { extraFunctions, customProp }`

-   * `"some \"quoted\" string and a \\ backslash"`
-   * `'a \'quoted\' symbol and a \\ backslash'`
-   * backslash `\` character now has to be escaped `\\`
-   * these expressions throw a syntax error: `"\'"`, `'\"'`, `"\n"` (use literal newline), `"\anythingother"`

- * Adds support for `in` operator with runtime arrays ([#14](https://github.com/cshaa/filtrex/issues/14))
-   *  `value in array` will return `1` when the value is present in the array and `0` otherwise
-   *  `array in array` will return `1` when the first array is a subset of the second one, `0` otherwise
-   *  `array in value` and `value in value` technically also work, they convert `value` to `[value]`
- 
- * Errors are no longer thrown, but instead catched and returned ([#7](https://github.com/cshaa/filtrex/issues/7))

 ## [1.0.0](https://github.com/cshaa/filtrex/releases/tag/v1.0.0)
- * **FIXED VULNERABILITY**: Not prone to XSS anymore ([#17j](https://github.com/joewalnes/filtrex/issues/17), [#18j](https://github.com/joewalnes/filtrex/issues/18))
- * **FIXED VULNERABILITY**: More robust against prototype attacks ([#19j](https://github.com/joewalnes/filtrex/pull/19), [#20j](https://github.com/joewalnes/filtrex/pull/20))
- * Adds TypeScript type definitions
- * Adds syntax for arrays: `(a, b, c)`
- * Adds the `of` property accessor: `a of b` translates to `data.b.a`
- * Adds the ability to customize the `prop` function ([#27j](https://github.com/joewalnes/filtrex/issues/27), [#28j](https://github.com/joewalnes/filtrex/pull/28))

 ## 0.5.4
- * The original version by [Joe Walnes](https://github.com/joewalnes)
- * **KNOWN VULNERABILITY**: Quotes can be exploited for XSS, see [#17j](https://github.com/joewalnes/filtrex/issues/17), [#18j](https://github.com/joewalnes/filtrex/issues/18)
- * **KNOWN VULNERABILITY**: Prototypes are accessible from expressions
