0.26.0

• Enabled TCP keepalive on socket level and support for setting socket options
  when creating the connection. The supported options are:

  • TCP_KEEPIDLE (overriding net.ipv4.tcp_keepalive_time)
  • TCP_KEEPINTVL (overriding net.ipv4.tcp_keepalive_intvl)
  • TCP_KEEPCNT (overriding net.ipv4.tcp_keepalive_probes)

• Propagate connect parameter pool_size to urllib3 as maxsize parameter
  in order to make the connection pool size configurable.
