Release Notes

binwiederhier/ntfy (ntfy)

v2.9.0

Compare Source

A small release after a long pause (lots of day job work). This release adds for larger messages and longer message delays in scheduled delivery messages. The web app also now supports pasting images from the clipboard. Other than that, only a few bug fixes and documentation updates, and a teeny tiny breaking change 😬.

⚠️ Breaking changes:

• The Rate-Topics header was removed due to a DoS issue (see #​1048). This only affects installations with visitor-subscriber-rate-limiting: true, which is not the default and likely very rarely used. Normally I'd never remove a feature, but this is a security issue, and likely affects almost nobody.

Features:

• Support for larger message delays with message-delay-limit (see message limits, #​1019, thanks to @​MrChadMWood for reporting)
• Support for larger message body sizes with message-size-limit (use at your own risk, see message limits, #​836/#​1050, thanks to @​zhzy0077 for implementing this, and to @​nkjshlsqja7331 for reporting)
• Web app: You can now paste images into the message bar or publish dialog (#​963/#​572, thanks to @​cmj2002 for implementing, and @​rounakdatta for reporting)

Bug fixes + maintenance:

• ⚠️ Remove Rate-Topics header due to DoS security issue if visitor-subscriber-rate-limiting: true (#​1048)

Documentation:

• Remove mkdocs-simple-hooks (#​1016, thanks to @​Tom-Hubrecht)
• Update Watchtower example (#​1014, thanks to @​lennart-m)
• Fix dead links (#​1022, thanks to @​DerRockWolf)
• PowerShell file upload example (#​1004, thanks to @​YMan84)

❤ Special thanks to @​wunter8 for always answering all the questions on Discord/Matrix!
