INSTALL: Update from site version

util.format: Expand explanation of purpose in comments

util.format: Skip control code escaping when doing full serialization Fixes that a multi-line string ended up "like\ \9this" instead of "like\nthis" as can be demonstrated by somehow initiating a connection to a HTTP server.

util.prosodyctl.cert: Look for certs matching 'http_host' This should ensure any certificate needed for HTTP services will also be included in the certificate import.

util.prosodyctl.check: Fix use of LuaSocket URL parser

util.prosodyctl.check: Add HTTP related DNS checks Since XEP-0363 is essentially mandatory now this will hopefully help diagnose some common issues.

util.prosodyctl.cert: Look for certificates in a consistent order Shortest first, then alphabetically, so that it prefers the base domain over subdomains. Fixes that it might otherwise pick a random sub-domain for filename on each run, cluttering the certs directory and potentially tricking Prosody into using an older certificate that might be about to expire.

mod_pubsub: Allow configuring summary templates Enables generation of summaries for more than Atom without additional modules.

mod_pubsub: Use the util.xtemplate to render Atom summary

util.xtemplate: Yet another string template library This one takes a stanza as input Roughly based on util.interpolation
