BIRD.vim 1.0.13

✨ Added / 新增

• 🛰️ BIRD 2.19 与 BIRD 3.3 配置语法 / BIRD 2.19 and BIRD 3.3 configuration syntax

  同步最新及较少使用的关键字、枚举、CLI 短语、运行时/接口属性、BGP
  hidden/unknown attributes、mac / mac set 类型及 bt_check_assign。

  Synchronized current and uncommon keywords, enums, CLI phrases,
  runtime/interface attributes, BGP hidden/unknown attributes, mac / mac set
  types, and bt_check_assign.

• 🧭 精确名称与目录识别 / Exact filename and directory detection

  新增 .bird、.bird2、.bird3、规范配置文件名，以及 bird、bird2、
  bird3 配置目录的精确识别。

  Added exact detection for .bird, .bird2, .bird3, canonical
  configuration filenames, and files under bird, bird2, or bird3
  configuration directories.

• 💬 可逆的注释映射 / Reversible comment mappings

  新增 buffer-local 普通模式与可视模式注释映射，并保留用户已有的
  <Leader>c 等映射；ftplugin 清理逻辑保持可逆。

  Added buffer-local normal and visual comment mappings while preserving user
  mappings such as <Leader>c; ftplugin cleanup remains reversible.

🔧 Changed / 变更

• 🔎 有界、注释感知的启发式检测 / Bounded, comment-aware heuristics

  通用 .conf 文件仅扫描前 200 行并忽略注释。BIRD 独有结构可直接命中，
  较通用结构必须同时出现两个独立信号；已有的非 conf filetype 不会被覆盖。

  Generic .conf files are scanned only through the first 200 lines with
  comments ignored. BIRD-specific structures match directly, while generic
  structures require two independent signals; existing non-conf filetypes
  are preserved.

• 🔄 支持稍后写入的配置内容 / Late-populated configuration support

  新增 FileType conf 与 BufWritePost 检测路径，可识别打开后才写入或生成的
  BIRD 配置。

  Added FileType conf and BufWritePost detection paths for BIRD
  configurations populated or generated after opening.

• 🧾 引入可审计的变更片段 / Adopt auditable change fragments

  新增零依赖的变更片段工作流，可在 PR 中记录语义版本级别和双语发布说明，
  并在发布时按分类汇总到 CHANGELOG。

  Added a dependency-free change-fragment workflow that records semantic
  version bumps and bilingual release notes in pull requests, then groups them
  into the changelog during release preparation.

🐛 Fixed / 修复

• 🐦 降低通用 .conf 误识别 / Reduced generic .conf false positives

  文件名仅包含 bird 不再触发识别，bluebird.conf、hummingbird.conf 以及
  nginx、Apache 等配置不会因为单个弱信号而被误判。

  A filename merely containing bird no longer triggers detection. Files such
  as bluebird.conf, hummingbird.conf, and nginx or Apache configurations are
  not classified from a single weak signal.

• 🗃️ typed table 识别边界 / Typed-table detection boundaries

  正确识别 eth table、neighbor table 与 ipv6 sadr table，同时排除并非
  table 声明的 address-family 标签。

  Correctly recognizes eth table, neighbor table, and ipv6 sadr table
  without treating address-family labels as table declarations.

• 🧵 字符串、操作符与前缀匹配 / Strings, operators, and prefix matching

  修复双引号转义、位运算符冲突、压缩 IPv6 前缀和 IPv4/IPv6 prefix range，
  并限制 IPv6 正则边界以避免异常长行产生额外开销。

  Fixed double-quoted escapes, bitwise-operator collisions, compressed IPv6
  prefixes, and IPv4/IPv6 prefix ranges, while bounding IPv6 matching on
  unusually long lines.

🧪 Verification / 验证

• 新增 headless syntax group、filetype detection 与 ftplugin 回归测试。
• Added headless syntax-group, filetype-detection, and ftplugin regressions.
• CI 覆盖 Vim v8.2.0000 与 stable，且语法文件与共享 canonical snapshot
  保持逐字节一致。
• CI covers Vim v8.2.0000 and stable and verifies that the syntax file is
  byte-identical to the canonical shared snapshot.

🔌 Compatibility / 兼容性

• 仓库由 BIRD2.vim 更名为 BIRD.vim，并提供 vim-plug、Vundle、原生 packages
  与手动 checkout 的双语迁移步骤。
• The repository was renamed from BIRD2.vim to BIRD.vim with bilingual
  migration steps for vim-plug, Vundle, native packages, and manual checkouts.
• 对外 filetype 仍为 bird2；既有 autocmd、映射、配置变量、runtime 文件名与
  :help bird2 均继续可用。
• The public filetype remains bird2; existing autocmds, mappings,
  configuration variables, runtime filenames, and :help bird2 references
  continue to work.
