TCEC S18 L3/L2/L1 Finished; CCC14?

Two weeks ago, in the previous post on the world's top two engine vs. engine competitions, the headline was TCEC: Stockfish Wins Cup 5, S18 Underway; CCC14?. To summarize the tournament situation at that time:-

TCEC: Stockfish beat LCZero in the final of TCEC Cup 5, while AllieStein beat Komodo in the consolation match. S18 League 3 is currently underway. • CCC: The series of exhibition events continues. The current event is 'ECO MegaMatch!' with 1080 games played out of 2099 scheduled.

Since then, the TCEC has progressed rapidly through three stages of season 18, while the CCC has been running a gigantic match between two top engines, cycling through the entirety of Encyclopedia of Chess Openings (ECO).

TCEC: S18 League 3 (L3) finished with Demolito and Gogobello promoting. S18 L2 finished with Booot and Pedone promoting, Demolito and Gogobello demoting. S18 L1 finished with Fire and rofChade promoting, RubiChess and Pedone demoting.

Of the four engines promoted from one league to the next higher league, three demoted from the higher league. Only Booot managed to keep a place in the higher league, where it tied for 3rd/4th in L1.

CCC: The current event, a bullet match, is 'ECO MegaMatch II! (1|1)'. After 1834 games, Lc0-dev leads Stockfish 934-900. Don't ask me the W-L-D score, because I don't find it available anywhere and I don't have the time to calculate it with a database. The 'Info' tab for the event says,

Games: 4048 • Estimated Time: 12 Days • Every opening in the ECO, played in order (2024 lines).

The schedule shows entries for 2014 games. Were the other 2034 games (4048 - 2014) played in the 'ECO MegaMatch! (1|1)' that I mentioned in the previous post? Maybe so, but that event is missing from the archive, meaning we can only guess. Whatever the case, the ECO lines are documented in ECOCodes (pastebin.com).

As for CCC14, there's still no news. Last week, in CCC Formats, I started documenting the formats for the first 13 seasons (it appears there have been 14 seasons, because the very first season was not numbered). What weird and wonderful format will the CCC organizers use this time?
