Full Changelog: v3.6.2...v3.7.0

v3.6.2

[3.6.2] - 2026-07-13

Fixed

• Cisco IOS-XR: the indent_adjust rule no longer misfires on the
  template data timeout and template options timeout leaves inside a
  flow exporter-map version block. Because no end-template follows these
  leaves, the parser previously nested every subsequent configuration line
  under them, silently collapsing the tree. Follow-up to #205 (#268).

v3.6.1

What's Changed

Added

• Nokia SRL platform driver (Platform.NOKIA_SRL) (#245)

Changed

• Renovate bot configuration to automate Poetry and GitHub Actions dependency updates

Fixed

• Huawei VRP: multiple peer-public-key blocks no longer raise DuplicateChildError (#266)
• Collapsed VLAN lines could produce a destructive no vlan x,y remediation on Cisco IOS (#264, #265)

Plus dependency and CI maintenance (poetry-core v2, pytest security update, actions/checkout & setup-python bumps).

v3.6.0

What's Changed

• Fix hash/eq inconsistency in HConfigChild (#185) by @jtdub in #235
• add huawei_vrp platform by @yanpla in #238
• Add Literal type for cisco_style_text() style parameter (#189) by @jtdub in #240
• Bump version to 3.6.0 and update docs/changelog by @jtdub in #243

Full Changelog: v3.5.1...v3.6.0

v3.5.1

What's Changed

Fixed

• DuplicateChildError raised when parsing IOS-XR configs with indented ! section separators (e.g., !, !). The per_line_sub regex was changed from ^!\s*$ to ^\s*!\s*$ so bare ! lines at any indentation level are stripped, restoring v3.4.2 behavior (#231).

Added

• Tests for IOS-XR indented ! section separator parsing, remediation no-ops with/without ! separators, differing comment text, and trailing comment edge case.

Full Changelog: v3.5.0...v3.5.1

v3.5.0

Added

• Unused object detection (#15): UnusedObjectRule, ReferenceLocation models, and unused_objects() method on HConfig. Not enabled in any driver by default — must be explicitly configured via driver extension or load_hconfig_v2_options.
• IOS-XR comment preservation (#30): ! comment lines inside sections are now attached to the next sibling's comments set instead of being stripped. Top-level ! delimiters and # comments are still removed.
• Negation regex substitution (#101): NegationSubRule model and negation_sub step in negate() for platform-specific negation transformations (e.g., truncating SNMP user removal commands).
• unused_objects and negation_sub processing in load_hconfig_v2_options.
• post_load_callbacks now run in get_hconfig_fast_load for consistency with get_hconfig.
• Idempotent command tests and improved IdempotentCommandsRule docstring (#61).
• exit_text_parent_level on SectionalExitingRule for IOS-XR end-* exit text rendered at parent indentation level (#130).

Fixed

• IOS-XR: DuplicateChildError when parsing configs with multiple group blocks (#209).
• pyproject.toml: Closed author email brackets, removed duplicate pylint extension, fixed typos (#190).

v3.4.3

Fixed

• IOS-XR: DuplicateChildError when parsing configs with multiple group
  blocks. Added SectionalExitingRule for group → end-group and a
  PerLineSubRule to indent end-group so it is treated as a section
  terminator rather than a standalone root-level child (issue #209).

v3.4.2

What's Changed

• Comprehensive documentation overhaul (issues #192–#201) by @jtdub in #203
• add test scenarios by @jtdub in #204
• test scenarios by @jtdub in #207
• Update the XR driver per github issues #205 and #206 by @jtdub in #208
