 # Define Symbols
-+ `DISABLE_POOLS_EVENTS` - выключает реактивное поведение в пулах.
-+ `ENABLE_DRAGONECS_DEBUGGER` - включает работу EcsDebug в релизном билде.
-+ `ENABLE_DRAGONECS_ASSERT_CHECKS` - включает опускаемые в релизном билде проверки.
+ `DRAGONECS_DISABLE_POOLS_EVENTS` - выключает реактивное поведение в пулах.
+ `DRAGONECS_ENABLE_DEBUG_SERVICE` - включает работу EcsDebug в релизном билде.
+ `DRAGONECS_STABILITY_MODE` - включает опускаемые в релизном билде проверки.
+ `DRAGONECS_DISABLE_CATH_EXCEPTIONS` - Выключает поведение по умолчанию по обработке исключений. По умолчанию фреймворк будет ловить исключения с выводом информации из исключений через EcsDebug и продолжать работу.
 + `REFLECTION_DISABLED` - Полностью ограничивает работу фреймворка с Reflection.
 + `DISABLE_DEBUG` - Для среды где не поддерживается ручное отключение DEBUG, например Unity.
 + `ENABLE_DUMMY_SPAN` - На случай если в среде не поддерживаются Span типы, включает его замену.
-+ `DISABLE_CATH_EXCEPTIONS` - Выключает поведение по умолчанию по обработке исключений. По умолчанию фреймворк будет ловить исключения с выводом информации из исключений через EcsDebug и продолжать работу.

 # Define Symbols
-+ `DISABLE_POOLS_EVENTS` - 禁用池子事件的响应行为。
-+ `ENABLE_DRAGONECS_DEBUGGER` - 在发布版中启用 EcsDebug 的工作。
-+ `ENABLE_DRAGONECS_ASSERT_CHECKS` - 在发布版中启用可忽略的检查和异常。
+ `DRAGONECS_DISABLE_POOLS_EVENTS` - 禁用池子事件的响应行为。
+ `DRAGONECS_ENABLE_DEBUG_SERVICE` - 在发布版中启用 EcsDebug 的工作。
+ `DRAGONECS_STABILITY_MODE` - 默认情况下，为了优化，框架在发布版本中跳过许多异常检查。此定义不是跳过检查，而是将其替换为能够解决错误的代码。这提高了稳定性，但降低了执行速度。
+ `DRAGONECS_DISABLE_CATH_EXCEPTIONS` - 禁用默认的异常处理行为。默认情况下，框架将捕获异常并通过 EcsDebug 输出异常信息，然后继续执行。
 + `REFLECTION_DISABLED` - 完全限制框架内部代码中的 Reflection 使用。
 + `DISABLE_DEBUG` - 用于不支持手动禁用 DEBUG 的环境，例如 Unity。
 + `ENABLE_DUMMY_SPAN` - 如果环境不支持 Span 类型，则启用它的替代。
-+ `DISABLE_CATH_EXCEPTIONS` - 禁用默认的异常处理行为。默认情况下，框架将捕获异常并通过 EcsDebug 输出异常信息，然后继续执行。

 # Define Symbols
-+ `DISABLE_POOLS_EVENTS` - disables reactive behavior in pools.
-+ `ENABLE_DRAGONECS_DEBUGGER` - enables EcsDebug functionality in release builds.
-+ `ENABLE_DRAGONECS_ASSERT_CHECKS` - enables omitted checks in the release build.
+ `DRAGONECS_DISABLE_POOLS_EVENTS` - Disables reactive behavior in pools.
+ `DRAGONECS_ENABLE_DEBUG_SERVICE` - Enables EcsDebug functionality in release builds.
+ `DRAGONECS_STABILITY_MODE` - By default, for optimization purposes, the framework skips many exception checks in the release build. This define, instead of disabling checks, replaces them with code that resolves errors. This increases stability but reduces execution speed.
+ `DRAGONECS_DISABLE_CATH_EXCEPTIONS` - Turns off the default exception handling behavior. By default, the framework will catch exceptions with the exception information output via EcsDebug and continue working.
 + `REFLECTION_DISABLED` - completely restricts the framework's use of Reflection.
 + `DISABLE_DEBUG` - for environments where manual DEBUG disabling is not supported, e.g., Unity.
 + `ENABLE_DUMMY_SPAN` - For environments where Span types are not supported, enables its replacement.
-+ `DISABLE_CATH_EXCEPTIONS` - Turns off the default exception handling behavior. By default, the framework will catch exceptions with the exception information output via EcsDebug and continue working.
