The 1.0-rc0 build had relatively few problems so I decided to declare it as the 1.0 release as to not block progress on OctoberPeaks (I once saw a subtle lighting glitch - not game-breaking - and some creative mode items can cause assertion failures - but this isn't supported for normal usage, just for mostly-internal testing, for now).

This also means it is worth reiterating the point of these phases of OctoberProject. OctoberPlains was the completion of phase1, which just involved building out core mechanics and proving that they work and that this design is feasible. OctoberPeaks is phase2, which is to build a client which actually provides a better and more fun interface.

The current plan is that OctoberPlains will also be updated for compatibility with OctoberPeaks, as that project progresses (or wraps up - the urgency of its updates will depend on how useful it is as a development tool).

In terms of OctoberPeaks, the first 1.0-pre0 release is planned to include the bare minimum required to use all of the mechanics of OctoberPlains 1.0. Note that this still won't include textures (so the world will only consist of "missing texture" images but will have the right shape), lighting, diagonal movement, audio, or any advanced models (every block is a cube and every entity is a rectangular prism). These features will be added over the course of the pre-release cycle, though.

While the OctoberPlains development cycle was heavy with breaking ground on all of the required mechanics, OctoberPeaks will be mostly just about improving the look and feel but will likely also extend into making the system easier to expand/modify, etc.

So, a basic "napkin plan" would look something like this:

OctoberProject 1.1 - added support for OctoberPeaks data and mutations.
OctoberProject 1.2 - More aggressive factoring of declarative data models so that the system can be more easily expanded through external data (not just blocks and crafting mechanics but also things like entity behaviours, to a minimal degree).

OctoberPlains 1.1 - Will depend on OctoberProject 1.1
OctoberPlains 1.2 - Will depend on OctoberProject 1.2

OctoberPeaks 1.0 - Will depend on OctoberProject 1.1, being feature-complete with OctoberPlains 1.0
OctoberPeaks 1.1 - Will depend on OctoberProject 1.2, including the changes to how the game blocks and mechanics are defined

Where things go after here will depend on what other issues come up along the way but it might be the point where phase 3 (OctoberSkies) gets started.

Thanks for checking it out,
