Log message:
py-scrapy: updated to 1.5.0

Scrapy 1.5.0:
This release brings small new features and improvements across the codebase.
Some highlights:

* Google Cloud Storage is supported in FilesPipeline and ImagesPipeline.
* Crawling with proxy servers becomes more efficient, as connections
  to proxies can be reused now.
* Warnings, exception and logging messages are improved to make debugging
  easier.
* scrapy parse command now allows to set custom request meta via
  --meta argument.
* Compatibility with Python 3.6, PyPy and PyPy3 is improved;
  PyPy and PyPy3 are now supported officially, by running tests on CI.
* Better default handling of HTTP 308, 522 and 524 status codes.
* Documentation is improved, as usual.

Backwards Incompatible Changes
* Scrapy 1.5 drops support for Python 3.3.
* Default Scrapy User-Agent now uses https link to scrapy.org.
  **This is technically backwards-incompatible**; override
  :setting:USER_AGENT if you relied on old value.
* Logging of settings overridden by custom_settings is fixed;
  **this is technically backwards-incompatible** because the logger
  changes from [scrapy.utils.log] to [scrapy.crawler]. If you're
  parsing Scrapy logs, please update your log parsers.
* LinkExtractor now ignores m4v extension by default, this is change
  in behavior.
* 522 and 524 status codes are added to RETRY_HTTP_CODES

Log message:
Scrapy 1.4 does not bring that many breathtaking new features
but quite a few handy improvements nonetheless.

Scrapy now supports anonymous FTP sessions with customizable user and
password via the new :setting:`FTP_USER` and :setting:`FTP_PASSWORD` settings.
And if you're using Twisted version 17.1.0 or above, FTP is now available
with Python 3.

There's a new :meth:`response.follow <scrapy.http.TextResponse.follow>` method
for creating requests; **it is now a recommended way to create Requests
in Scrapy spiders**. This method makes it easier to write correct
spiders; ``response.follow`` has several advantages over creating
``scrapy.Request`` objects directly:

* it handles relative URLs;
* it works properly with non-ascii URLs on non-UTF8 pages;
* in addition to absolute and relative URLs it supports Selectors;
  for ``<a>`` elements it can also extract their href values.

Log message:
Changes 1.3.3:
Bug fixes
- Make ``SpiderLoader`` raise ``ImportError`` again by default for missing
  dependencies and wrong :setting:`SPIDER_MODULES`.
  These exceptions were silenced as warnings since 1.3.0.
  A new setting is introduced to toggle between warning or exception if needed ;
  see :setting:`SPIDER_LOADER_WARN_ONLY` for details.

Log message:
