We've pushed the first incremental update to the 1.0 beta of this cycle, 1.0.0-beta.2, which can be downloaded from the website.
Part of the beta process involves testing, identifying regressions and applying bugfixes, and as such we will release updates to the beta as needed, with an expected frequency of roughly once per week. This push includes a merge from the nightly branch, bringing 1.0 completely up to date with nightly. For the rest of this development cycle we currently intend to only cherry-pick further fixes, which is the model that will be taken for updating the beta branch from here out.
We have no changelog for this update, but the final stable release will include a complete changelog for the 1.0 cycle.
I expect that these incremental updates to betas will not be highly-publicized in the future as they will be regular occurrences and not worth creating release notes for individually, but as the process gets started and people are migrating to beta it seems prudent to attempt keep people informed for now. Curious for others' opinions.
