## ✨ Features

### Analyzer

- **Number operators**: adds opt-in arithmetic for `BcMath\Number` and `GMP` via `allow-operator-overloading`. (#2486, #2487, 0fff359)

## 🐛 Bug Fixes

### Analyzer

- **Native type contracts**: keeps native types and nullability when PHPDoc conflicts. (#2494, 2dc705f)
- **Inline @var tags**: no longer treats unassigned local variables as defined. (#2496, 56f2ad9)
- **Malformed PHPDoc**: reports malformed types and unresolved variable links. (#2493, c1cdff1)
- **Conditional variables**: reports possibly undefined variables after switch and in finally. (#2497, e378e5d)
- **Iterator types**: keeps current() and key() types without explicit generics. (#2476, 467b29d)
- **Array unions**: preserves left-hand values and optional keys with array-key key types. (#2485, #2488, 782b0b5)
- **Empty checks**: handles unset variables and falsy values correctly. (#2484, 8dc47c5)
- **Dynamic properties**: honors AllowDynamicProperties on classes and their ancestors. (#2483, 6bccb58)
- **Deprecated members**: reports access to deprecated properties and class constants. (#2478, 90fa5e5)
- **Deprecated scopes**: skips deprecation warnings inside already deprecated code. (#2492, d412c32)
- **Boolean assignments**: avoids false narrowing when loops update boolean flags. (#2499, 64ad7d6)
- **Iterable assertions**: narrows traversables without false impossible-condition reports. (#2508, ac54e6c)

### Codex

- **Patch flags**: applies supported PHPDoc flags and their negations from type patches. (#2477, #2495, 29f3416)

### Formatter

- **Stable layouts**: keeps concatenations, arrow functions, and assignments stable across passes. (#2491, 9f4804d)
- **Parenthesized comparisons**: keeps comparison layouts stable when operands use parentheses. (#2480, f2fdf5f)

### Prelude

- **Base64 decoding**: returns string for non-strict decoding. (#2511, 4918783)

## 📖 Documentation

### Configuration

- **Operator settings**: documents opt-in number operators in English, French, and Chinese. (#2487, 0fff359)
- **Patch flags**: documents supported PHPDoc patch flags in English, French, and Chinese. (#2495, 29f3416)

## 🏗️ Internal

### Analyzer

- **Named arguments**: speeds up argument matching and default type inference. (#2498, 2f7475f)
- **Member checks**: cuts reference scans and allocations when checking unused members. (cc19617)
- **Default arguments**: skips needless type expansion for omitted non-generic defaults. (#2506, #2507, 6590a7b)

### Codex

- **Reference lookups**: speeds up reference queries and merges. (23ebbf2)

### Formatter

- **Formatting work**: cuts allocations and layout work. (a2e8ae5)

### Guard

- **Dependency scans**: skips unused dependency files and cuts allocations. (dae8785)
