Wow, welcome back!
As you know, progress began to be very scarce and slow at some point, and my computer died this summer, so the situation was kind of frozen with no one to code. In October, Zeality officially removed Crimson Echoes from the site's main priorities. I repaired my computer/bought new parts around that time, so I came back and resumed the coding. Things began to run smoothly again, and from October to December the events of the game were polished from the prologue up to the beginning of Marle's chapter in the Reptite timeline (that's about 26% of the game according to the current plot outline).
In early December, I was about to reach the point where I'd have to actually code new stuff instead of just polishing existing events, but I decided to take a short break to go back to "Prophet's Guile" and finish it in time for a Christmas/New Year release. Prophet's Guile is another secret ROM hack, which Zeality launched in January 2007 as a side-project of sorts and which was supposed to be "lightning-developed" in just one month. Well, it had actually dragged up to May, when I had sort of abandoned it to return to Crimson Echoes. So in December we picked up Prophet's Guile again and actually just finished it yesterday (it will be released soon).
That's basically what happened during your absence. The current plot outline has been put on a private wiki at:
http://www.chronocompendium.com/Term/CEWith the big lulls and since my polishing was done chronologically, I don't think I've ever reached the Kasmir Fortress part (the current "frontier" in the playable game is the Reptite timeline chapters). It's definitely still there in the ROM though, and will be reached and polished in due time.
Feel free to tackle the Porre Lab. Note that the blue stuff in the changelog are what's new relative to the previous patch, rather than what's new since you left, but you probably noticed it already (there's a lot of new stuff, eh?). You're coming back at a perfect time, since now that Prophet's Guile is almost "out of the way", the focus can be on Crimson Echoes again. Take a look at the plot outline and go wild!
