Here is a brief list of the bigger changes since 1.7:

Native Telnet Support

• TelnetConnector and TelnetListener - Zeus finally supports native Telnet, alongside the existing serial/modem lines. TelnetListener answers incoming connections on a TCP port and passes them to a line; TelnetConnector then behaves just like the classic Connector. Run as many TelnetConnectors as you have telnet lines.
• TelnetS (secure Telnet over TLS) is also supported, using the optional AmiSSL v5 integration. Prefs/Lines gains certificate generation.
• BBSLine's pipe buffers have been increased from 1KB to 32KB per pipe, needed to give adequate file transfer performance over Telnet - the old size was tuned for 33.6k modems.

• Fixed a long-standing performance bug in fbzeus.library: deleted file records were expunged - the more you deleted, the slower uploads got. Saving and describing files is fixed accordingly.
• fbTrim() (and the FileRebuild PURGE option) is much improved
• fbSaveFile() is now atomic and performance is massively improved on large filebases.

• ZPOP3Xfer supports POP3S (POP3 over SSL/TLS, port 995, requires AmiSSL v5), and multiple mail configurations.
• ZMP gains a CONFIGTEST switch to sanity-check a configuration without running any tasks - handy for scripted setup checks.

• A new daily SysOp report tool for scripts: lists users and files pending validation, freshly auto-created message areas, areas not in any SIG, and checks TelnetS certificate expiry (warning under 30 days, critical under 5 days or already expired).

• A security review of zeus.library, zmf.library, Zeus, BBSLine, ZMailer and ZMP turned up and fixed several buffer overflow issues.
• zeus.guide has been substantially reorganised and extended, with new sections covering Telnet, file catalogue maintenance and more.
