was 0. An upgrade is recommended. See the release announcement in the

release corrects a bug where chloglevel would not properly work. Thanks
to the folks at OSU Engineering for finding the bug. An upgrade is
recommended.

release is strictly a bugfix regarding the default values in
etc/netviewer.conf. If you already have an existing installation, you do

release addresses a bug and expands on the mult functionality in
previous releases.

allow RPN expressions. Default behavior of importer has changed
to always query the device after importing a configuration.

release implements features in netviewer.cgi that existed in the
backend for awhile. Namely, it allows you to specify 'mult' or 'units'
for something you wish to graph. See ChangeLog for additional details.
2005 April 06:
Released netviewer-0.29.6. I
discovered a typo in etc/categories that may create problems. This
release corrects that typo.
2005 April 06:
Released netviewer-0.29.5. This
marks the first public and stable release of netviewer from the 0.29
branch. If you are still running 0.28.x version of netviewer, please
carefully read the documentation regarding upgrading to 0.29.
The previous, internal 0.29.4 release has been quite stable. This release has some minor bug fixes, but is primarily meant to indicate that 0.29 is ready for public consumption.
2005 March 25:
Released netviewer-0.28.4. This
release is a bugfix that resolves a bug when trying to insert data

before upgrading.

release is a bugfix against 0.28.2 and continues the work of improving
build times where sites use extensive test expressions.

Released netviewer-0.28.2. This
release fixes issue during rebuilds where the test expression does
not cache results for a given query. For sites with an extensive
test expression, they will have observed poor rebuild times. There may
be subsequent releases later this week as the more extensive use of
caching in the unstable 0.29 branch is backported to 0.28 branch.
2004 July 21:
Released netviewer-0.28.1. New

incorrect config file), and NetViewer.pm and how it builds locale
info.

Released netviewer-0.28. New release adds
support for high-counter CAR stats and changes how locale RRDs are created
