# Important: #82230 - Updates to the Fluid template engine library

See [forge#82230](https://forge.typo3.org/issues/82230)

## Description

This article describes the changes that have been added to the Fluid template engine which is used in TYPO3.

-   Bug fix to evaluate negative numbers in conditions the same way PHP does
-   Bug fix for `getLayoutPathAndFilename` on `TemplatePaths` when property was manually set using setter
-   Bug fix to avoid issues with malformed cache identifiers
-   Bug fix to avoid attempting `htmlspecialchars()` on any values that are not string-compatible
-   Bug fix for adding namespaces to list of ignored namespaces
-   Bug fix to make casting of ints/floats consistent in attribute values and in array values
-   Bug fix to make internal cache of resolved ViewHelpers non-static to make sure it flushes between contexts
-   Bug fix for recursive file resolving
-   Performance bug fix to avoid loading compiled template classes that are already loaded
-   Performance bug fix to make `f:render` static callable from compiled templates
-   Performance bug fix to improve performance of uncompilable templates
-   New feature: support for `hasMyProperty()` as alternative to `isMyProperty()` when using `{object.myProperty}`
-   New feature: `ParserRuntimeOnly` ViewHelper trait to use when ViewHelper only has functionality during parsing
-   New feature: `ignoreEmptyAttributes()` added to `TagBuilder`, can be called in tag based ViewHelpers to skip
    rendering of any attributes that evaluate to an empty string
-   New feature: support for `AND` and `OR` as alternatives to `&&` and `||` in boolean attributes like
    `condition` on `f:if`
-   New feature: support for custom error handling and a new implementation of a fault-tolerant error handler
-   New feature: methods `getAll` and `addAll` added to `ViewHelperVariableContainer` to allow getting and setting
    all variables in a scope
-   New feature: concept of `Renderable` introduced. A `Renderable` is any class which implements
    `RenderableInterface` \- instances of such classes can be assigned as template variables and passed to `f:render`
