This is a big version.
Basically we cleaned up our file object implementation and replaced it with [smart-open](https://github.com/RaRe-Technologies/smart_open)
A well known package that give us file object optimized for big files streaming to s3 service using boto3.
Version Bug Fix list:
* 64
* 61
* 58
* 55
* 39
Behavior changes:
* file object readlines instance method:
When opening a file in a not binary mode.
The behavior of this method is deferent between Python version and file read mode (binary or text).
For example please see the [test_read_lines_hint](https://github.com/liormizr/s3path/blob/master/tests/test_path_operations.py#L255) unit test
* file object write instance method:
From now we will see the Key in the Bucket only after closing the file object
