*
### Fixed
* fixed the inconsistencies in API and CLI docstrings
* `blob_announce` error when announcing a single blob
* `blob_list` error when looking up blobs by stream or sd hash
* issue#1107 whereing claiming a channel with the exact amount present in wallet would give out proper error
* Fix channel creation to use same bid logic as claim ([1148])(https://github.com/lbryio/lbry/pull/1148)
* incorrectly raised download cancelled error for already verified blob files
* infinite loop where reflector client keeps trying to send failing blobs, which may be failing because they are invalid and thus will never be successfully received
### Deprecated
* `report_bug` jsonrpc command
*
*
### Changed
* reflector server to periodically check and set `should_announce` for sd and head blobs instead of during each request
* reflector server to use `SQLiteStorage` to find needed blob hashes for a stream
*
*
### Added
* scripts to autogenerate documentation
* now updating new channel also takes into consideration the original bid amount, so now channel could be updated for wallet balance + the original bid amount
* forward-compaitibility for upcoming DHT bencoding changes
* `blob_reflect` command to send specific blobs to a reflector server
*
### Removed
* short(single dashed) arguments for `lbrynet-cli`
* `flags` decorator from server.py as short flags are no longer used when using api/cli methods
*
## [0.19.1] - 2018-03-20
### Fixed
* Fixed the inconsistencies in API and CLI docstrings
* `blob_announce` error when announcing a single blob
* `blob_list` error when looking up blobs by stream or sd hash ([1126](https://github.com/lbryio/lbry/pull/1126))
* Claiming a channel with the exact amount present in wallet would return a confusing error ([1107](https://github.com/lbryio/lbry/issues/1107))
* Channel creation to use same bid logic as for claims ([1148](https://github.com/lbryio/lbry/pull/1148))
### Deprecated
* `report_bug` jsonrpc command
### Changed
* Bumped `lbryschema` requirement to 0.0.15 [see changelog](https://github.com/lbryio/lbryschema/blob/master/CHANGELOG.md#0015---2018-03-20)
* Bumped `lbryum` requirement to 3.2.0 [see changelog](https://github.com/lbryio/lbryum/blob/master/CHANGELOG.md#320---2018-03-20)
* Reflector server to periodically check and set `should_announce` for sd and head blobs instead of during each request
* Reflector server to use `SQLiteStorage` to find needed blob hashes for a stream
### Added
* Scripts to auto-generate documentation ([1128](https://github.com/lbryio/lbry/pull/1128))
* Now updating new channel also takes into consideration the original bid amount, so now channel could be updated for wallet balance + the original bid amount ([1137](https://github.com/lbryio/lbry/pull/1137))
* Forward-compatibility for upcoming DHT bencoding changes
### Removed
* Short(single dashed) arguments for `lbrynet-cli`
## [0.19.0] - 2018-03-02

pip install --editable .

This will update `lbrynet-daemon` and other executables.
This will install `lbrynet-daemon` in such a way that the changes you make to the code will be used as soon as you restart the daemon.
Happy hacking!
