Release notes

Sourced from gcovr's releases.

8.7

Breaking changes:

• Jinja2 environment for HTML report is now created with undefined=StrictUndefined to raise an error if a variable is not defined in the template. (#1282, #1283)
• Links to lines in HTML reports now use L<line> instead of a l<line>. (#1285)
• Rename config key txt-metric (string) to txt-metrics (list of strings in TOML and multiple entries in gcovr.config). Remove the deprecated aliases -b, --txt-branches and --branches. (#1302)
• Adjust column width of total count in text reports. (#1302)

New features and notable changes:

• Improve HTML report:
  • Improve wrapping of the counter in the default theme. (#1236)
  • Replace meter with div elements in the default theme (like in GitHub themes). (#1236)
  • Add jinja2 rendering for CSS files. (#1252)
  • Add new HTML themes boost.green and boost.blue. (#1248, #1271)
  • Show excluded lines, branches, ... in the summary only if there are any. (#1287)
  • Remove the branches summary and columns if there are no branches in the report, e.g all branches are excluded by patterns or comments. (#1305)
  • Replace default theme with github theme which is the new default one. If the prefix github. isn't used a warning is printed which will turn into an error in a the next version. (#1313)
• Add compare mode for JSON, text and HTML reports. (#1240, #1266)
• Stub missing line coverage for branches in LLVM source based code coverage format. (#1245)
• Add support for TOML files with --config (#1258)
• Add --fail-under-condition-or-decision with --fail-under-condition and --fail-under-decision as synonyms, change the key for the configuration file. (#1293)
• Add support for multiple metrics in one text report and add support for condition coverage. (#1302)
• Warn if a option is used which has no effect when processing tracefiles. (#1307)
• Add options to restrict where GCOV is executed to prevent generating temporary files in arbitrary directories. Write protected files are now skipped by default. (#1311)

Bug fixes and small improvements:

• Fix runtime problem introduced with 8.4. (#1270)
• Fix boost HTML details and simple output. (#1274)
• Fix boost HTML support for Conditions, Decisions and Calls optional stats. (#1277)
