IMPROVEMENTS - Add statistics reporting via Datadog. (optional feature) - Improve exception handling and reporting, particularly for agent-sid errors.
0.8.5
------------------
FIXES - It now copes with API requests without bodies at all: use an empty string to generate signatures. - Enabled authorization checks to stream-mode APIs, which has been disabled for debugging and tests. (Though the probability of exposing kernels to other users was very low due to randomly generated kernel IDs.)
0.8.4
------------------
FIXES - Stabilized sporadic restarts/disconnects of agent instances, and keep the concurrency usage consistent. - Increased the minimum size of aioredis connection pools to avoid rare deadlocks due to pool exhaustion.
0.8.3
------------------
FIXES - Make sure all errorneous responses to contain RFC 7807-style JSON-formatted error messages using aiohttp middleware.
0.8.1
------------------
FIXES - Assume date headers in HTTP request headers without timezone offsets as UTC instead of showing internal server error.
0.8.0
------------------
NEW - Deprecated legacy ZMQ interface. The code is still there, but should not be used. - Refined keypair/usage database schema. - Implemented the streaming-mode API: web terminal! - Restarting the kernel in the middle of web termainl session are transparently handled -- user's browser-side websocket connections are preserved. - The codebase now requires Python 3.6.0 or higher. - Internally it adopted a simple event bus to handle asynchronous docker events such as abnormal termination of kernels. Now most interactions with docker are truly asynchronous.
