Release release-3.3.1 · skx/rss2email

This release primarily focuses upon being a better network client:

We avoid fetching the full-contents of every feed when we're executing.
- Instead we only fetch a feed once at startup.
- Subsequent fetches will add If-Modified-Since, or Etag headers in our outgoing requests.
- This should mean that we don't fetch the full contents of feeds that haven't changed unnecessarily.
Related to this our frequency handling has changed.
- In the past we used to wake up, between sleeps, every fifteen minutes to process feeds.
- Now we wake up more often, but we still check feeds at 15minute intervals by default.
- The new, per-feed, frequency argument will be used to specify the minimum poll-frequency - this can drop to 5 minutes now, but will default to 15 minutes to match past behaviour.
- It is preferred that feeds which don't change too often will have suitable values configured.
TLS / SSL failures can be ignored by default
- Add the new insecure: true setting as a per-feed option to disable certificate checks.
Feeds with duplicated links will be better handled.
- We'll attempt to uniquely identify feeds with identical items, via the addition of a # value.
Finally our logging has been overhauled a little
- The old LOG_ALL environmental variable has been replaced by a new LOG_LEVEL setting. This allows a finer-grained control of logging output.
- Also we support a log-file now, by default.
