+# DotCov 2.0.0
+
+The same Cobertura report can produce different numbers than in 1.x. Two parser fixes change
+what DotCov counts, so thresholds and badges set on 1.x numbers can move. Commands, flags,
+exit codes and the JSON shape are unchanged.
+
+## What changes in your numbers
+
+- **istanbul reports (Jest, Vitest): line totals now equal the tool's own.** istanbul lists each
+  function's declaration line under `<methods>`, and 1.x counted those lines as file lines. A
+  class's own `<lines>` now decide its file's lines; method lines count only for a class that has
+  no `<lines>` of its own. Coverlet's totals do not change. On ten Vitest reports from the MCP
+  TypeScript SDK, every line total now equals Vitest's; with 1.7.1, all ten were higher, by up to
+  823 lines.
+- **coverage.py with several `source` roots: each file keeps its own root.** 1.x prefixed every
+  relative file name with the first `<source>`. A file now resolves against the root under which
+  it exists on disk, so run DotCov where the sources are checked out. When the file exists under
+  no root or under several, the first root applies and the report keeps the multi-root warning.
+  On the MCP Python SDK's report (three roots, 414 files), 413 files now resolve to their real
+  paths.
+- The multi-root warning now appears only when a file stays ambiguous, not for every report
+  with several roots.
+
+## What DotCov cannot change
+
+istanbul attaches branches only to lines that hold statements. A branch on any other line exists
+only in the report's header totals, so DotCov's branch count can stay below Jest's or Vitest's
+summary. The README's TypeScript section says so too.
+
+## Upgrade
+
+```bash
+dotnet tool update -g DotCov.Tool --version 2.0.0
+```
+
+Update the badge action to `ANcpLua/dotcov/.github/actions/badge@v2.0.0` and the `DotCov` and
+`DotCov.Fallout` package references to `2.0.0`.
