We plan to designated this the 1.0.0 DNS-STATS Compactor release. There are a number of significant changes that were required to support the more flexible specification introduced since the -04 version of the C-DNS draft that is the basis of the current 0.12 release. This email is intended to provide a timeline for the 1.0.0 release and an outline of the changes.<br class=""><br class="">Timeline<br class="">----------<br class="">We plan to do a 1.0.0-beta1 release on Friday 27th Sept. We expect to have at least two months of beta testing, possibly longer. Please note:<br class=""><br class="">* Version 1.0.0 will be backwards compatible with C-DNS files produced by all previous versions of the DNS-STATS Compactor. In other words in version 1.0.0:<br class=""> ** compactor will write only version 1.0 C-DNS as defined in RFC8618<br class=""> ** inspector will read version 1.0 C-DNS files and also the two older private C-DNS formats (0.2 and 0.5) used by the previous DNS-STATS Compactor releases.<br class="">* The default behaviour does not change in the 1.0.0 release compared to the 0.12 release but there are additional configuration files required/available.<br class="">* We are asking users to test the beta code, but are *not* recommending it for production use until the official 1.0.0 release happens later this year. <br class=""><br class=""><br class="">Overview of changes<br class="">----------------------------<br class="">* The most significant change is that in the 1.0 C-DNS format almost all the fields are optional, whereas in the earlier draft specification a minimum set of fields was always captured. The default behaviour of the DNS-STATS Compactor remains the same: all fields are captured.<br class="">* The ‘include’ parameter in the compactor configuration file is deprecated in 1.0.0 as it cannot provide the full flexibility required by the 1.0 C-DNS specification. It is replaced by a new file ‘excluded_fields.conf’ which allows for fine grained management of specific data fields. The ‘include’ parameter will be removed in a future release.<br class="">* This new optionality adds complexity to PCAP reconstruction for cases where not all data was captured. A new file specifying defaults for potentially missing fields is introduced in 1.0.0, which in installed by default and must be present when reconstructing PCAPS.<br class=""><br class="">The 1.0.0 code is currently available in a branch on GitHub:<br class=""><a href="https://github.com/dns-stats/compactor/tree/feature/v1.0.0" class="">https://github.com/dns-stats/compactor/tree/feature/v1.0.0</a><div class="">The Changelog is here:</div><div class="">https://github.com/dns-stats/compactor/blob/feature/v1.0.0/ChangeLog.txt<br class="">And the updated 1.0.0.
