How can I see the status of the latest CyanogenGen builds? I see that CM10 nightlies for galaxysmtd have not been built for a while.  Is the status of the latest builds available anywhere, so that I can see why they haven't been built?
Rule of CM - never ask for ETA's, changelogs! 

Only recourse is to look up the review site instead and filter it out for the appropriate device instead to see what code changes were checked in/rejected, in this case, use this as a search query on the top right hand corner of the page.

status:open project:CyanogenMod/android_device_samsung_galaxysmtd


Then can drill down the review, depending on what type of CyanogenMod ROM, be it GB, ICS or JB.

Usually, there is a reason as to why there's no build, check with their forum or IRC channel. :)
