v0.9.6 - Stable

Markdown table escape for pipes and newlines

Version 0.9.6 - 2026-05-12

Markdown table hardening surfaced by the post-polish audit pass.
Diff::to_markdown() (under the markdown feature) now escapes
the two characters that previously corrupted the surrounding
|-delimited table layout when they appeared inside a check
name: the pipe itself, and line breaks.

Highlights

• Diff::to_markdown() escapes | and newlines inside
  check-name cells of the Severity changes and Duration
  regressions tables. A check named a|b|c previously
  corrupted the surrounding |-delimited table layout,
  shifting every later column on the row. Newlines inside a
  check name had the same effect — the rendered table would
  break on the embedded line. Both forms are now safe: |
  becomes \|, and \n / \r becomes <br>. The rendered
  cell carries the original text visually intact while the
  table structure stays well-formed.

Breaking changes

None. The fix only affects cells that previously rendered
broken markdown. Any check name that did not contain a |,
\n, or \r produces byte-identical output to 0.9.5.

Internals

• New helper escape_table_cell() in the markdown module
  centralizes the two substitutions (| -> \|, \n / \r
  -> <br>).
• New test diff_table_escapes_pipes_in_check_names exercises
  the regression with a check name containing two pipes and
  asserts the rendered table parses as a well-formed markdown
  table.

Notes

• No new runtime dependencies.
• No schema changes; schema_version stays at 1.
• MSRV unchanged at Rust 1.85.
• Recommended upgrade for anyone rendering diffs through the
  markdown feature whose check names may contain |
  characters (common for parameterized test names) or
  multi-line context.
