- Default PROXY_CPUS and PROXY_MEMORY now empty (use full system resources)
- Docker run skips --cpus/--memory flags when not set
- Dockerfile: enable LTO, codegen-units=1 for optimized binary
- check_update_sha_bg(): background SHA fetch on TUI startup, sets
badge file when new commits are available on main
- Main menu shows update banner when badge exists
- self_update(): download from main, SHA256 compare, backup, install,
auto-regenerate + restart Telegram service after update
- Works without GitHub releases — every push to main is detectable
In bash, \n in double-quoted strings is literal backslash+n, not a
newline character. curl --data-urlencode sends them as %5Cn and
Telegram renders them literally in message text, causing \n\n to
appear visibly around proxy links.
Fix: run msg through printf '%b' in telegram_send_message() and
tg_send() to convert \n to actual newlines (0x0A) before the string
is URL-encoded and sent to the Telegram API.
Validated: _esc() markdown escapes (\_, \*) are unaffected since
underscore and asterisk are not printf escape sequences.
- Add get_cached_ip() with 5-minute TTL to bot service; replaces raw
curl to api.ipify.org in tg_send(), /mp_link, /mp_add, /mp_rotate
- Escape server label with _esc() in tg_send() and tg_send_photo()
headers so underscores/asterisks don't break Telegram Markdown
- Escape label with _esc() in all error message strings across handlers
- Refactor update_traffic() to fetch /metrics once and pass raw data
to get_user_stats_tg() — eliminates one curl per user per interval
- get_user_stats_tg() accepts pre-fetched metrics as optional arg
- /mp_secrets fetches metrics once before iterating users
- Fix /mp_remove: check label existence first, then guard against
removing the last secret with a clear dedicated error message
- Implement real iptables/ipset geo-blocking with ipdeny.com CIDR lists
- Tag-based cleanup (mtproxymax-geoblock comment, mtpmax_ ipset prefix)
- Batch ipset loading via restore for fast rule application
- Auto-reapply geo-blocks on proxy start, full cleanup on uninstall
- Fix _repeat() and _strlen() to use pure bash (no subprocesses)
- Cache docker inspect result across main menu renders
- Cache get_public_ip() for 5 minutes, reduce timeout 5s -> 3s
- Parse proxy stats with single read instead of 3 awk subprocesses
- Cache _cached_start_epoch outside render loop
- Add comprehensive README with feature docs, comparison table,
user management recipes, and practical examples
Blocking a user prevents them from interacting with repositories, such as opening or commenting on pull requests or issues. Learn more about blocking a user.
