Version 2.11.0 (Jan 29, 2026)

• This release improves binding performance using CPython's adaptive specializing interpreter (PEP 659 <https://peps.python.org/pep-0659/>__). The speedups are automatic and require no changes to binding code:

  .. list-table:: :header-rows: 1

  • • Operation
    • Speedup
    • Requirements
  • • Method calls
    • 1.22x faster
    • Python 3.11+
  • • Static attribute lookups
    • 1.63x faster
    • Python 3.14+

  This was achieved by making a number of nanobind-internal classes (nb_func, nb_method, nb_meta, etc.) immutable, which allows CPython to specialize generic LOAD_ATTR opcodes to faster type-specific versions (LOAD_ATTR_METHOD for method calls, LOAD_ATTR_CLASS for static attribute lookups). (PR [#1257](https://github.com/wjakob/nanobind/issues/1257) <https://github.com/wjakob/nanobind/pull/1257>__).

• Added the :cpp:class:nb::never_destruct <never_destruct> class binding annotation to inform nanobind that it should not bind the destructor. (PR [#1251](https://github.com/wjakob/nanobind/issues/1251) <https://github.com/wjakob/nanobind/pull/1251>, commit 4ba51f <https://github.com/wjakob/nanobind/commit/4ba51fcf795971c5d603d875ae4184bc0c9bd8e6>).

• Argument annotations for std::optional<T>-typed arguments now implicitly have the :cpp:func:.none() <arg::none> annotation applied (i.e., no need to additionally specify nb::arg("..").none()). (PR [#1262](https://github.com/wjakob/nanobind/issues/1262) <https://github.com/wjakob/nanobind/pull/1262>, commit 425ca1 <https://github.com/wjakob/nanobind/commit/425ca1d10dfda60de122d681099500f6e9718985>).

• Removed a redundant hash table type, reducing the size of libnanobind by 2.5KiB. (commit 4d53cd <https://github.com/wjakob/nanobind/commit/4d53cd184a759129122d678466b7055aef3dfac6>__).

• Added Python 3.12-3.14 symbols to linker scripts. (commit 36d4a6 <https://github.com/wjakob/nanobind/commit/36d4a60bd1f9ecb4ac6c42489db29719c5b3d77a>__).

• Fixed a bug where call_guard could cause an extra copy of the return value. (PR [#1249](https://github.com/wjakob/nanobind/issues/1249) <https://github.com/wjakob/nanobind/pull/1249>__).

• Don't link nb_ft.cpp in non-free-threaded builds to avoid linker warnings about empty compilation units. (PR `#1271
