Added PHP 8 support

November 26 took place official release of PHP 8. The new version is already available to all users usual and business hosting.

Major improvements and innovations in the new version:

• Union Types (type unions) - allows you to explicitly specify two or more valid value types.
• Named Arguments (named arguments) - passing values by name to a function.
• Match Expressions (selection operator match) is a more convenient replacement for switch in some aspects.
• Attributes (attributes) is a new way to bind metadata to classes.
• Constructor Property Promotion (shorthand syntax for combining class and constructor properties) - syntactic sugar to simplify the initialization of class fields in the constructor.
• Nullsafe Operator (safe null operator) - allows you to bypass separate conditional checks for null when calling method chaining.
• Weak Maps (link maps) - a special data structure for storing values with object keys.
• Just In Time Compilation (JIT compilation) - allows you to get a noticeable performance gain when performing operations for which processor performance is of primary importance, such as complex mathematical operations.

For more information on the changes, see official announcement... A complete list of changes is available in changelog.

You can enable PHP 8 on hosting in PHP settings... We recommend that you first make sure that the site code is compatible with the new version.
