* Fixed a bug where keywords could not be used in function position (#174)
* Fixed a bug where macro symbols were not resolved using the same heuristics as other symbols (#183)
* Fixed a bug where lazy sequences were not resolved even if they were empty-checked (#182)
* Fixed a bug where new namespaces were created whenever the compiler checked if a namespace existed to resolve a symbol (#211)
* Fixed a bug where Python string escape sequences were not handled correctly by the reader (#192)
* Fixed a bug where character literals caused a syntax error inside collections (#192)
## [v0.1.dev1] - 2018-09-13
### Added
* Basic CLI for REPL and running scripts
* REPL convenience functions `doc` and `pydoc` will return Basilisp and Python documentation respectively
* Vars containing the last 3 expression results (`*1`, `*2`, `*3`) and last exception (`*e`) are now included on the REPL
* Added support for [Decimal](https://docs.python.org/3/library/decimal.html), [Fraction](https://docs.python.org/3/library/fractions.html), and [complex](https://docs.python.org/3/library/stdtypes.html#numeric-types-int-float-complex) types
* Support for Clojure style object instantiation syntax: `(new com.lisp.Object)` or `(com.list.Object.)`
* Read/eval functions in `basilisp.core`
* Support for customizing data readers either by binding `*data-readers*` or supplying a keyword argument from Python
* Support for character literals using `\a` syntax
* Support for deref-literals using `@`
### Fixed
* Dynamic vars are now properly compiled as dynamic, allowing thread-local bindings
* `let*` bindings can no longer eagerly evaluate binding expressions in conditional branches which will not be taken
* `catch` expressions no longer throw an error when they appear in a syntax-quote
* Basilisp files imported using the Basilisp import hook now properly resolve symbols in syntax quotes
* Basilisp's `Map` type now supports `cons`ing other maps.
* Syntax quoted special forms are no longer resolved into namespaced symbols
## [v0.1.dev0] - 2018-08-31
