- Update to 0.6.0:
* Fixed issues with filesystem instance caching. This was causing authorization errors in downstream libraries like gcsfs and s3fs in multi-threaded code (:pr:`155`, :pr:`181`)
* Changed the default file caching strategy to :class:`fsspec.caching.ReadAheadCache` (:pr:`193`)
* Moved file caches to the new fsspec.caching module. They're still available from their old location in fsspec.core, but we recommend using the new location for new code (:pr:`195`)
* Added a new file caching strategy, :class:`fsspec.caching.BlockCache` for fetching and caching file reads in blocks (:pr:`191`).
* Fixed equality checks for file system instance to return False when compared to objects other than file systems (:pr:`192`)
* Fixed a bug in :meth:`fsspec.FSMap.keys` returning a generator, which was consumed upon iteration (:pr:`189`).
* Removed the magic addition of aliases in AbstractFileSystem.__init__. Now alias methods are always present (:pr:`177`)
* Deprecated passing trim to :class:`fsspec.spec.AbstractBufferedFile`. Pass it in storage_options instead (:pr:`188`)
* Improved handling of requests for :class:`fsspec.implementations.http.HTTPFileSystem` when the HTTP server responds with an (incorrect) content-length of 0 (:pr:`163`)
* Added a detail=True parameter to :meth:`fsspec.spec.AbstractFileSystem.ls` (:pr:`168`)
* Fixed handling of UNC/DFS paths (:issue:`154`)
