I know rocket fuel crafting time must have been halved sometime in 2.0.x as i have used ratio of 2 blue assemblers to 1 chemical plant in 0.18 and solid fuel crating time was halved in 2.0.7.
However the wiki doesn't list this change.

Re: Rocket fuel - crafting time halved - [changelog]
The Rocket Fuel recipe's InfoBox was updated on the wiki (back in Oct 2024), to indicate crafting time reduced from 30 to 15, but the change isn't in any change notes. Anyhow, I've updated the 2.0.7 change history section on the Rocket Fuel page: https://wiki.factorio.com/Rocket_fuel
The other 2.0.7 change was for the stack size (increased from 10 to 20) and that is already shown in the change notes.Decreased the crafting time of rocket fuel from 30 to 15.

Rocket ingredients and related items were mentioned several times in the 2.0.7 release announcement, directly next to the stack size change.
