Release 0.4.17

Ipfs 0.4.17 is a quick release to fix a major performance regression in bitswap (mostly affecting go-ipfs -> js-ipfs transfers). However, while motivated by this fix, this release contains a few other goodies that will excite some users.

The headline feature in this release is urlstore support. Urlstore is a generalization of the filestore backend that can fetch file blocks from remote URLs on-demand instead of storing them in the local datastore.

Additionally, we've added support for extracting inline blocks from CIDs (blocks inlined into CIDs using the identity hash function). However, go-ipfs won't yet create such CIDs so you're unlikely to see any in the wild.

Features:

• URLStore (ipfs/go-ipfs#4896)
• Add trickle-dag support to the urlstore (ipfs/go-ipfs#5245).
• Allow specifying how the data field in the object get is encoded (ipfs/go-ipfs#5139)
• Add a -U flag to files ls to disable sorting (ipfs/go-ipfs#5219)
• Add an efficient --size-only flag to the repo stat (ipfs/go-ipfs#5010)
• Inline blocks in CIDs (ipfs/go-ipfs#5117)

Changes/Fixes:

• Make ipfs files ls -l correctly report the hash and size of files (ipfs/go-ipfs#5045)
• Fix sorting of files ls (ipfs/go-ipfs#5219)
• Improve prefetching in ipfs cat and related commands (ipfs/go-ipfs#5162)
• Better error message when ipfs cp fails (ipfs/go-ipfs#5218)
• Don't wait for the peer to close it's end of a bitswap stream before considering the block "sent" (ipfs/go-ipfs#5258)
• Fix resolving links in sharded directories via the gateway (ipfs/go-ipfs#5271)
• Fix building when there's a space in the current directory (ipfs/go-ipfs#5261)

Documentation:

• Improve documentation about the bloomfilter config options (ipfs/go-ipfs#4924)

General refactorings and internal bug fixes:

• Remove the Offset() method from the DAGReader (ipfs/go-ipfs#5190)
• Fix TestLargeWriteChunks seek behavior (ipfs/go-ipfs#5276)
• Add a build tag to disable dynamic plugins (ipfs/go-ipfs#5274)
• Use FSNode instead of the Protobuf structure in PBDagReader (ipfs/go-ipfs#5189)
• Remove support for non-directory MFS roots (ipfs/go-ipfs#5170)
• Remove UnixfsNode from the balanced builder (ipfs/go-ipfs#5118)
• Fix truncating files (internal) when already at the correct size (ipfs/go-ipfs#5253)
• Fix dagTruncate (internal) to preserve the node type (ipfs/go-ipfs#5216)
• Add an internal interface for unixfs directories (ipfs/go-ipfs#5160)
• Refactor the CoreAPI path types and interfaces (ipfs/go-ipfs#4672)
• Refactor precalcNextBuf in the dag reader (ipfs/go-ipfs#5237)
• Update a bunch of dependencies that haven't been updated for a while (ipfs/go-ipfs#5268)
