[0.3.0] - 2025-01-16

New Features

• Streaming uploads. obstore.put now supports iterable input, and obstore.put_async now supports async iterable input. This means you can pass the output of obstore.get_async directly into obstore.put_async. by @kylebarron in developmentseed/obstore!54
• Allow passing config options directly as keyword arguments. Previously, you had to pass all options as a dict into the config parameter. Now you can pass the elements directly to the store constructor. by @kylebarron in developmentseed/obstore!144
• Readable file-like objects. Open a readable file-like object with obstore.open and obstore.open_async. by @kylebarron in developmentseed/obstore!33
• Fsspec integration by @martindurant in developmentseed/obstore!63
• Prefix store by @kylebarron in developmentseed/obstore!117
• Python 3.13 wheels by @kylebarron in developmentseed/obstore!95
