Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.
In Prettier 3.1.1, you can use --no-error-on-unmatched-pattern to simply skip symbolic links.

If an .editorconfig file is in your project and it sets max_line_length=off for the file you're formatting,

(which previously resulted in the default printWidth of 80 being applied, if not overridden by Prettier-specific configuration).

};Group params in opening block statements (#14067 by @jamescdavis)
This is a follow-up to #13930 to establish wrapping consistency between opening block statements and else blocks by grouping params in opening blocks. This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.

Prettier now switches to using the resolve module for resolving configuration files and plugins if it detects that require.resolve isn't Node's builtin function (doesn't support the second argument), which happens in environments like editor extensions. To force the fallback, set the PRETTIER_FALLBACK_RESOLVE environment variable to true.

TypeScript: Add trailing comma in tsx, only for arrow function (#6190 by @sosukesuzuki)
Prettier inserts a trailing comma to single type parameter for arrow functions in tsx, since v 1.18. But, this feature inserts a trailing comma to type parameter for besides arrow functions too (e.g, function , interface). This change fix it.
// Input interface Interface1<T> { one: "one"; } function function1<T>() { return "one"; } // Output (Prettier 1.18.0) interface Interface1<T,> { one: "one"; } function function1<T,>() { return "one"; } // Output (Prettier 1.18.1) interface Interface1<T> { one: "one"; } function function1<T>() { return "one"; }

HTML: Do not format non-normal whitespace as normal whitespace (#5797 by @ikatyang)
Previously, only non-breaking whitespaces (U+00A0) are marked as non-normal whitespace, which means other non-normal whitespaces such as non-breaking narrow whitespaces (U+202F) could be formatted as normal whitespaces, which breaks the output. We now follow the spec to exclude all non-ASCII whitespace from whitespace normalization.

JavaScript: Do not format functions with arguments as react hooks (#5778 by @SimenB)
The formatting added in Prettier 1.16 would format any function receiving an arrow function and an array literal to match React Hook's documentation. Prettier will now format this the same as before that change if the arrow function receives any arguments.
// Input ["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce( (allColors, color) => { return allColors.concat(color); }, [] ); // Output (Prettier 1.16.0) ["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce(( allColors, color ) => { return allColors.concat(color); }, []); // Output (Prettier 1.16.1) ["red", "white", "blue", "black", "hotpink", "rebeccapurple"].reduce( (allColors, color) => { return allColors.concat(color); }, [] );

JavaScript: Add necessary parentheses for decorators (#5785 by @ikatyang)
Parentheses for decorators with nested call expressions are optional for legacy decorators but they're required for decorators in the current proposal.

TypeScript: Stable parentheses for function type in the return type of arrow function (#5790 by @ikatyang)
There's a regression introduced in 1.16 that parentheses for function type in the return type of arrow function were kept adding/removing. Their parentheses are always printed now.
// Input const foo = (): (() => void) => (): void => null; const bar = (): () => void => (): void => null; // First Output (Prettier 1.16.0) const foo = (): () => void => (): void => null; const bar = (): (() => void) => (): void => null; // Second Output (Prettier 1.16.0) const foo = (): (() => void) => (): void => null; const bar = (): () => void => (): void => null; // Output (Prettier 1.16.1) const foo = (): (() => void) => (): void => null; const bar = (): (() => void) => (): void => null;
