    them all into a single string.

aliasses
  - `app.script_name` returns the name of the current script (previously a \ 
private function)

[#293](https://github.com/Tieske/Penlight/pull/293)

### Fixes

  - `utils.raise` changed the global `on_error`-level when passing in bad arguments
  - `utils.writefile` now checks and returns errors when writing
  - `compat.execute` now handles the Windows exitcode -1 properly
  - `types.is_empty` would return true on spaces always, indepedent of the parameter
  - `types.to_bool` will now compare case-insensitive for the extra passed strings
  - `app.require_here` will now properly handle an absolute base path
  - `stringx.split` will no longer append an empty match if the number of requested
    elements has already been reached \ 
[#295](https://github.com/Tieske/Penlight/pull/295)
  - `path.common_prefix` and `path.relpath` return the result in the original casing
    (only impacted Windows) [#297](https://github.com/Tieske/Penlight/pull/297)
  - `dir.copyfile`, `dir.movefile`, and `dir.makepath` create the new file/path with
    the requested casing, and no longer force lowercase (only impacted Windows)
    [#297](https://github.com/Tieske/Penlight/pull/297)
  - added a missing assertion on `path.getmtime` \ 
[#291](https://github.com/Tieske/Penlight/pull/291)
  - `stringx.rpartition` returned bad results on a not-found \ 
[#299](https://github.com/Tieske/Penlight/pull/299)

## 1.6.0 (2018-11-23)
### New features

  - `pl.compat` now provides `unpack` as `table.unpack` on Lua 5.1

### Changes

  - `utils.unpack` is now documented and respects `.n` field of its argument.
  - `tablex.deepcopy` and `tablex.deepcompare` are now cycle aware (#262)
  - Installing through LuaRocks will now include the full rendered documentation

### Fixes

  - Fixed `seq.last` returning `nil` instead of an empty list when given an \ 
empty iterator (#253).
  - `pl.template` now applies `tostring` when substituting values in templates, \ 
avoiding errors when they are not strings or numbers (#256).
  - Fixed `pl.import_into` not importing some Penlight modules (#268).
  - Fixed version number stuck at 1.5.2 (#260).
  - Fixed `types.is_empty` returning `true` on tables containing `false` key (#267).
  - Fixed `test.assertraise` throwing an error when passed an array with a \ 
function to call plus its arguments (#272).
  - Fixed `test.assertraise` not throwing an error when given function does not \ 
error but instead returns a string matching given error pattern.
  - Fixed placeholder expressions being evaluated with wrong precedence of \ 
binary and unary negation.
  - Fixed placeholder expressions being evaluated assuming wrong binary operator \ 
associativity (e.g. `_1-(_2+_3)` was evaluated as `(_1-_2)+_3`.
  - Fixed placeholder expressions being evaluated as if unary operators take \ 
precedence over power operator (e.g. `(-_1)^_2`) was evaluated as `-(_1^2)`).
  - Fixed vulnerable backtracking pattern in `pl.stringx.strip` (#275)
