v1.7.1

No backwards incompatible changes here.

Fixes

• fix mass resubscribe after several Redis disconnects in a row - more details in #163

Features

• update Gorilla Websocket lib - it now tries to reuse buffers returned from Go http library hijack method. We adapted Centrifugo default websocket buffer options to utilize this feature (websocket_read_buffer_size and websocket_write_buffer_size now 0 by default).
