Best regards,

= Week 11 =

== What I did this week ==
This week I worked mostly on Volumetric optimizations.
* Avoid some calculations for Volume Lamp Sampling. Now we only 
calculate what is necessary for Equi-Angular, and then in case we have a 
valid scattering event, we do the remaining parts. This could be 
optimized further, by avoiding the pre calculations, in case we only use 
Distance Sampling. I also need to double check the correctness for Mesh 
Lights, it seems that there is a remaining issue. (9406c1989536, 
776ce62bee4d).

* Optimize heterogeneous volume shadow. This gives a few percent 
speedup, but needs to be tested with more files still. (1f432d2b06c4, 
8f5eb7a5638d)

* Cleanup: Avoid intermediate function when we sample all lamps. 
(|773c58524d8e)

* Update stdosl.h for OSL 1.5. (59f4ba854b34)

* Make Glass shader default to 1.0 color. (564c48a06868)

* Bug tracker maintenance (check on reports, bisected one Cycles issue, 
close invalid/fixed ones...)

== Next week ==
Finish the volume optimizations and merge them to master.

== Questions ==
None.
