Dear PMC,

I’m requesting PMC approval for PDT 8.4 minor release that is scheduled to coincide with Eclipse 2025-12. This is first minor release since a long time (over 1.5 year)

Release contains both bug fixes and new features

PMI + N&N: https://projects.eclipse.org/projects/tools.pdt/releases/8.4/review

Key changes:

    Initial PHP 8.4 and PHP 8.5 support: #315

        property hooks - 8.4

        asymmetric visibility - 8.4

        new MyClass()->method() without parentheses - 8.4

        pipe |> operator - 8.5

        Clone with _expression_ - 8.5

        static lambda as static _expression_ - 8.5

    Support for Eclipse Terminal plugin (TM terminal replacement)

    Improved Getter / Setter generator

        Read property type and use it as setter argument type and getter return type

        Allow to generate setter with return type void or self for method chain

    Fix arrow function nesting #311

    Synchronize some dependencies with Eclipse release
