ntfy

This is a hotfix release, mostly to combat the ridiculous amount of Matrix requests with invalid/dead pushkeys, and the corresponding HTTP 507 responses the ntfy.sh server is sending out. We’re up to >600k HTTP 507 responses per day 🤦. This release solves this issue by rejecting Matrix pushkeys, if nobody has subscribed to the corresponding topic for 12 hours.

The release furthermore reverts the default rate limiting behavior for UnifiedPush to be publisher-based, and introduces a flag to enable subscriber-based rate limiting for high volume servers.

Features:

• Support SMTP servers without auth (#645, thanks to @Sharknoon for reporting)

Bug fixes + maintenance:

• Token auth doesn’t work if default user credentials are defined in client.yml (#650, thanks to @Xinayder)
• Add visitor-subscriber-rate-limiting flag to allow enabling subscriber-based rate limiting (off by default now, #649/#655, thanks to @barathrm for reporting, and to @karmanyaahm and @p1gp1g for help with the design)
• Reject Matrix pushkey after 12 hours of inactivity on a topic, if visitor-subscriber-rate-limiting is enabled (#643, thanks to @karmanyaahm and @p1gp1g for help with the design)

Additional languages:

• Danish (thanks to @Andersbiha)
