Since the releases are not hosted on SpigotMC itself I kinda forgot to post it as a resource update here. NBTAPI 2.9.2 adds 1.18.2 support, so 1.18.2-1.7.10 is supported. The releases are available via maven too.
Changes(since 2.8.0):

• Added 1.18/1.18.1/1.18.2 support
  
• Fixes files not getting closed in case of an exception during saving of NBTFiles(thanks honkling)
• Adds more info to exceptions
• Adds config value to do a startup without self-check or log messages(because for some reason people like server logs not saying anything?!?)
• Tweaked some error messages to be more descriptive
• Removed usage of System.out
