[Rebuild] update 25 April

[Richard Weait]

Hello,

Rebuilding continues.  Redaction tests are still being refined.
According to best estimates we are close to cracking this, but it's a
complex area - passing tests will be the benchmark here.  Of the
remaining tests,  five concern nodes, seven concern ways, five concern
relations and 1 relates to significant tag changes.  There were more
than 20 commits[1] to the license change branch of the code this week,
from four authors. Your contributions are welcome.

Once the tests are passing, live data testing will be conducted
against a test server that is already configured and waiting. Subject
to a successful test, a bounding-box test of the live database will be
processed, most likely for the island of Ireland. After this
successfully processes, the rest of the data set can be processed to
completion.

Best regards,
Richard on behalf of
Communication Working Group
