This is a list of the most important changes for each version.

0.8 – June 20, 2011

This release involved big refactorings. The addition of branches, particularly, changes the DB schema, so that old DBs will need to be migrated. See instructions.

Major features:

  • acdha added support for git and github
  • Danilo implemented branches. A revision is now always associated to a branch, and different branches can be compared in the Comparison view
  • Server Logging
  • David Fraser added new documentation explaining the Codespeed views and concepts

0.7 – Jan 20, 2011

Major features:

  • New home page with result Reports: show summary of latest benchmark runs
  • RSS feed showing Reports
  • Support for Netbooks, tablets, and smartphones screen sizes through the use of media query
  • Big performance improvements in the Changes and Timeline views
  • Added settings for change and trend thresholds and default comparison executables

0.6 – June 23, 2010

This release brings a new view, together with many other changes. Unfortunately the DB Schema had to be changed, so it is not compatible with existing databases without migration. The decision was taken in order to make the executable model simpler.

  • DB Modifications:
    • Executable: removed coptions and added a description fields. This is the main reason for a DB change, as it really didn’t bring much and it made things unecessarily complicated
    • Benchmark: Added a units_title field, which is used as plot title
    • Charfield lengths where adjusted
  • New feature: Comparison view
    • Normal bar charts
    • Cumulative bar charts
    • Relative bar charts
    • Horizontal or verical orientation
  • Name change: Overview became Changes
    • Removal of inline plot bars (covered now by the comparison view)
    • Added environment and executable info box
  • Timeline view:
    • The baseline is now selectable
    • Added plot title


The focus of this release was polishing, making everything work seamlessly and cementing the DB design. The DB Schema should remain stable from now on. Last but not least, the installation and configuration process of codespeed was greatly simplified and is now documented.

Codespeed is now considered to be ready for general use.
Thanks go to Joe and to Oriol Rius for their feedback, which made this posible.
