[dependabot]

Updates the requirements on nanobind to permit the latest version.

Changelog

Sourced from nanobind's changelog.

Version 2.6.1 (Mar 28, 2025)

• nanobind assigns an ABI tag to compiled extensions and uses it to isolate incompatible extensions from each other. This tag was unnecessarily fine-grained, often causing isolation where an actual ABI compatibility was not present. This release updates the tagging scheme to address this long-standing inconvenience. (PR [#778](https://github.com/wjakob/nanobind/issues/778) <https://github.com/wjakob/nanobind/pull/778>__).

• Added specialized function dispatchers to accelerate calls to 0 and 1-argument functions. (PR [#944](https://github.com/wjakob/nanobind/issues/944) <https://github.com/wjakob/nanobind/pull/944>__).

• Improved the efficiency of :cpp:func:nb::getattr(obj, key, default) <getattr> in cases where obj[key] does exist. (commit bb05f5 <https://github.com/wjakob/nanobind/commit/bb05f5503aef9b70498302bf30bf958e8cc605c7>__).

• ABI version 16.

• Miscellaneous fixes and improvements (PRs [#913](https://github.com/wjakob/nanobind/issues/913) <https://github.com/wjakob/nanobind/pull/913>, [#914](https://github.com/wjakob/nanobind/issues/914) <https://github.com/wjakob/nanobind/pull/914>, [#916](https://github.com/wjakob/nanobind/issues/916) <https://github.com/wjakob/nanobind/pull/916>, [#931](https://github.com/wjakob/nanobind/issues/931) <https://github.com/wjakob/nanobind/pull/931>, [#978](https://github.com/wjakob/nanobind/issues/978) <https://github.com/wjakob/nanobind/pull/978>, commit 1595d2 <https://github.com/wjakob/nanobind/commit/1595d2d40717d65835ed984b06cfc2b4da0e4858>).

Version 2.6.0 (Mar 28, 2025)

• This release was yanked due to a regression.

Version 2.5.0 (Feb 2, 2025)

• Added :cpp:class:nb::def_visitor\<..\> <def_visitor>, which can be used to define your own binding logic that operates on a :cpp:class:nb::class_\<..\> <class_> when an instance of the visitor object is passed to :cpp:func:class_::def(). This generalizes the mechanism used by :cpp:class:init, :cpp:class:new_, etc, so that you can create binding abstractions that "feel like" the built-in ones. (PR [#884](https://github.com/wjakob/nanobind/issues/884) <https://github.com/wjakob/nanobind/pull/884>__)

• Added some special forms for :cpp:class:nb::typed\<T, Ts...\> <typed> (PR [#835](https://github.com/wjakob/nanobind/issues/835) <https://github.com/wjakob/nanobind/pull/835>__):

  • nb::typed<nb::object, T> or nb::typed<nb::handle, T> produces a parameter or return value that will be described like T in function
