Release Notes

nedbat/coveragepy (coverage)

v7.5.3

• Performance improvements for combining data files, especially when measuring
  line coverage. A few different quadratic behaviors were eliminated. In one
  extreme case of combining 700+ data files, the time dropped from more than
  three hours to seven minutes. Thanks for Kraken Tech for funding the fix.

• Performance improvements for generating HTML reports, with a side benefit of
  reducing memory use, closing issue 1791_. Thanks to Daniel Diniz for
  helping to diagnose the problem.
