## ✨ 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)

### 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)
