Sourced from werkzeug's changelog.

Version 0.15.3

Released 2019-05-14

• Properly handle multi-line header folding in development server in
  Python 2.7. (:issue:1080)
• Restore the response argument to :exc:~exceptions.Unauthorized.
  (:pr:1527)
• :exc:~exceptions.Unauthorized doesn't add the WWW-Authenticate
  header if www_authenticate is not given. (:issue:1516)
• The default URL converter correctly encodes bytes to string rather
  than representing them with b''. (:issue:1502)
• Fix the filename format string in
  :class:~middleware.profiler.ProfilerMiddleware to correctly handle
  float values. (:issue:1511)
• Update :class:~middleware.lint.LintMiddleware to work on Python 3.
  (:issue:1510)
• The debugger detects cycles in chained exceptions and does not time
  out in that case. (:issue:1536)
• When running the development server in Docker, the debugger security
  pin is now unique per container.

Version 0.15.2

Released 2019-04-02

• Rule code generation uses a filename that coverage will ignore.
  The previous value, "generated", was causing coverage to fail.
  (:issue:1487)
• The test client removes the cookie header if there are no persisted
  cookies. This fixes an issue introduced in 0.15.0 where the cookies
  from the original request were used for redirects, causing functions
  such as logout to fail. (:issue:1491)
• The test client copies the environ before passing it to the app, to
  prevent in-place modifications from affecting redirect requests.
  (:issue:1498)
• The "werkzeug" logger only adds a handler if there is no handler
  configured for its level in the logging chain. This avoids double
  logging if other code configures logging first. (:issue:1492)
