New Features
* Added support for auto-resolving namespaces for keyword from the current namespace using the `::kw` syntax (576)
* Added support for namespaced map syntax (577)
* Added support for numeric constant literals for NaN, positive infinity, and negative infinity (582)
* Added `*basilisp-version*` and `*python-version*` Vars to `basilisp.core` (584)
* Added support for function decorators to `defn` (585)
* Added the current Python version (`:lpy36`, `:lpy37`, etc.) as a default reader feature for reader conditionals (585)
* Added default reader features for matching Python version ranges (`:lpy36+`, `:lpy38-`, etc.) (593)
* Added `lazy-cat` function for lazily concatenating sequences (588)
* Added support for writing EDN strings from `basilisp.edn` (600)
* Added a persistent queue data type (606)
* Added support for transducers (601)
* Added support for Python 3.9 (608)
* Added support for 3-way comparators (609)
Changed
* Moved `basilisp.lang.runtime.to_seq` to `basilisp.lang.seq` so it can be used within that module and by `basilisp.lang.runtime` without circular import (588)
* Keyword hashes are now pre-computed when they are created, so they do not need to be recomputed again to be fetched from the intern cache (592)
* The compiler now uses the pre-computed hash to lookup keywords directly, which should improve lookup time for repeated invocations (592)
* Symbol hashes are now pre-computed when they are created (592)
* Moved `basilisp.core.template` to `basilisp.template` to match Clojure (599)
* Refactor compiler to use `functools.singledispatch` for type based dispatch (605)
* Rename `List`, `Map`, `Set`, and `Vector` to `PersistentList`, `PersistentMap`, `PersistentSet`, and `PersistentVector` respectively (605)
Bug Fixes
* Fixed a bug where `def` forms did not permit recursive references to the `def`'ed Vars (578)
* Fixed a bug where `concat` could cause a `RecursionEror` if used on a `LazySeq` instance which itself calls `concat` (588)
* Fixed a bug where map literals in function reader macro forms caused errors during reading (599)
* Fixed a bug where `some->` and `some->>` threading macros would thread `nil` first arguments (599)
Removed
* Removed `pyfunctional` dependency in favor of Python standard library functions (589)
Other
* Basilisp uses `poetry` for dependency and virtual environment management, as well as for publishing to PyPI (616)
