Clear message

Code changes should include an overview of what needs to change, and in some cases even the specific details.

Migration

Include:

  • data migration, if any
  • redirects from old URLs to new ones, if any
  • how users will be pointed to the new way of doing things, if necessary.

Test/Demo Plan

It's important that we are able to test new features, and demonstrate them to users. Use this section to describe a short plan that anybody can follow that demonstrates the feature is working. This can then be used during CD testing, and to show off after release.

This need not be added or completed until the specification is nearing beta.

To build packages, when using debhelper, using lzma compression you need to use: dh_builddeb -- -Zlzma

Example: openoffice.org-core (data.tar.*)

If we were to convert the entire Ubuntu 7.10 alternate cd to each of the following formats it would be the following sizes:

original

gzip

bzip2

lzma

675,113,008

706,435,778

640,232,610

500,868,452

The following ODS file has a comparison of the sizes of all packages on the Ubuntu 7.10 Alternate CD compressed with gzip, bzip2, lzma compared to what is currently in the archive:

Outstanding Issues

This should highlight any issues that should be addressed in further specifications, and not problems with the specification itself; since any specification with problems cannot be approved.

BoF agenda and discussion

Use this section to take notes during the BoF; if you keep it in the approved spec, use it for summarising what was discussed and note any options that were rejected.
