Changes for version 0.112 - 2026-09-05
- Extend first-class cached constructor callbacks to Kernel::Event, Kernel::Timer, Kernel::Signal, Kernel::Process, and IO::Sock::Dgram. Public leaves can now be used directly while subclass methods retain the cached fast path and may be overridden per object.
- Document subclassing prominently as the declarative home for native framers, TLS, socket policy, and Stream, Datagram, and Process tuning. Add live delivery, override, lexical-retention, validation, and terminal callback-release tests for the expanded constructor API.
- Add first-class constructor callbacks for ordered-byte input and lifecycle events on Pipe, TTY, connected Stream, and accepted Stream objects. Constructor callbacks override same-named class methods for that instance.
- Cache the effective raw, framed, and batched input callback directly in native stream state, preserving direct CV dispatch and compatible instance callbacks across protocol transitions.
- Let Listener constructors provide one shared callback set for every accepted Stream, without allocating per-connection wrapper closures.
- Add lifecycle, transition, teardown, Listener propagation, and callback retention coverage plus permanent construction, raw-dispatch, and framed-dispatch regression benchmarks.
- Add a high-level Stream comparison harness for raw and delimiter-framed Linux::Event, AnyEvent, UV, IO::Async, and Mojo adapters. Keep this optional-dependency benchmark outside the CPAN distribution and installation test suite.
- Document callback signatures, mode validation, class-policy boundaries, Listener template reuse, and cached-CV dispatch throughout public POD and design documents. Compile every public POD SYNOPSIS and execute the Pipe and connected-Stream callback examples during testing.
