v2.2.1¶

Features

Add NTC Templates v9.1 commands to Cisco family — cisco_nxos / cisco_xr / cisco_asa: 19 commands total. Includes manual cisco_asa netmiko init compat (show curpriv / terminal pager 0 etc.) (#151)
Add NTC Templates v9.1 commands to non-Cisco batch — fortinet / juniper_junos / paloalto_panos / arista_eos: 30 commands total (#154)
Add NTC Templates v9.1 commands to Huawei family — huawei_smartax / huawei_vrp: 39 commands total (#160)
Add show privilege to cisco_ios for Ansible compatibility, mark cisco_ios as Ansible-verified in compatibility table (#124)

Bug Fixes

Rewrite gen_docs_platform_commands invoke task: handle commands without output field, use str.format() for {base_prompt} substitution to match runtime semantics, regenerate all 50 platform docs with correct rendering (#146)
Render escaped brace literals ({{ ... }}) correctly in platform docs by switching docs generator to str.format(), matching cmd_shell.default runtime. Affects 10 platforms with literal braces in fixtures (huawei_smartax, juniper_junos, cisco_asa, cisco_ios, cisco_nxos, hp_comware, arista_eos, paloalto_panos, oneaccess_oneos, huawei_vrp) (#160)

Tooling

Improve sync_ntc_commands.py: prefer canonical raw fixture, retain alternate fixtures as output_variants, filter sibling-fixture noise (#147)
Auto-escape literal {xxx} patterns in sync_ntc_commands.py output (preventive escape) so that runtime str.format() is safe for any NTC fixture content (#156)

Tests

Add tests/test_gen_docs_platform_commands.py pinning render_template formatter semantics (substitution, escape unescape, error context) to prevent future regression of brace rendering (#160)

CI/CD

Enable pytest-xdist parallel execution by default (addopts = "-vv -n auto"). Local measurement: 18:06 → 3:01 (6.0x speedup) (#164)
Remove Docker-first tasks (build / clean / rebuild / pytest / cli / tests) and dead code from tasks.py, drop INVOKE_LOCAL from CI workflows (#145)

Features

Add 9 new platforms from NTC Templates v9.0: aruba_aoscx, cisco_apic, cisco_viptela, cisco_wlc_ssh, edgecore, extreme_slxos, oneaccess_oneos, watchguard_firebox, zte_zxros (#129)
Add 28 new commands to cisco_ios from NTC Templates v9.1, including SD-WAN, CTS, endpoint-tracker, and license commands (#128)

Tests

Add netmiko connection tests for all YAML-only platforms (#129)
Refine test skip logic with granular skip_enable_platforms instead of full-platform xfail (#129)

Documentation

Add CONTRIBUTING.md with bilingual support (English / Japanese), AI Transparency policy, and contribution workflow (#121)
Add SECURITY.md with bilingual support pointing to GitHub Private Vulnerability Reporting (#120)
Convert platform compatibility list to detailed compatibility table with notes (#129)

Security

Upgrade dependencies to fix 7 Dependabot alerts: urllib3, filelock, virtualenv, pynacl (#111)

Bug Fixes

Resolve Docker Trivy scan failure (zlib CVE) with apk upgrade --no-cache (#102)

Fix BrokenPipeError on Telnet authentication failure (#102)

CI/CD

Change publish workflow triggers from tag push to release event to prevent premature publishing (#103)

Features

Echo coalescing for SSH and Telnet servers — prevents intermittent empty output with netmiko send_command() (#87, #94)
Telnet server plugin with RFC 854/857/858 compliance
Thread-safe TapIO I/O bridge shared by SSH and Telnet servers
