## 0.11.0 (unreleased)
* BREAKING CHANGE: defpath renamed to defnav
* BREAKING CHANGE: path renamed to nav
* BREAKING CHANGE: fixed-pathed-path and variable-pathed-path renamed to fixed-pathed-nav and variabled-pathed-nav
* New `path` macro does intelligent inline caching of the provided path. The path is factored into a static portion and into params which may change on each usage of the path (e.g. local parameters). The static part is factored and compiled on the first run-through, and then re-used for all subsequent invocations. As an example, `[ALL (keypath k)]` is factored into `[ALL keypath]`, which is compiled and cached, and `[k]`, which is provided on each execution. If it is not possible to precompile the path (e.g. [ALL some-local-variable]), nothing is cached and the path will be compiled on each run-through.
* Added `must-cache-paths!` function to throw an error if it is not possible to factor a path into a static portion and dynamic parameters.
* BREAKING CHANGE: all select/transform/setval/replace-in functions changed to macros and moved to com.rpl.specter.macros namespace. The new macros now automatically wrap the provided path in `path` to enable inline caching. Expect up to a 100x performance improvement without using explicit precompilation, and to be within 2% to 15% of the performance of explicitly precompiled usage.
* Added select*/transform*/setval*/replace-in*/etc. functions that have the same functionality as the old select/transform/setval/replace-in functions.
* Added `must-cache-paths!` function to throw an error if it is not possible to factor a path into a static portion and dynamic parameters.
* BREAKING CHANGE: `defpath` renamed to `defnav`
* BREAKING CHANGE: `path` renamed to `nav`
* BREAKING CHANGE: `fixed-pathed-path` and `variable-pathed-path` renamed to `fixed-pathed-nav` and `variabled-pathed-nav`
* Added `must` navigator to navigate to a key if and only if it exists in the structure
* Added `ATOM` navigator (thanks @rakeshp)
* Added "navigator constructors" that can be defined via `defnavconstructor`. These allow defining a flexible function to parameterize a defnav, and the
function integrates with inline caching for high performance.
