Update.
Heavy fighting is continuing around Aleppo, specifically in an SAA attempt to cut the city off from the highway to Idlib. Strategic reserves have been deployed, including 240mm mortars, and Tochka ballistic missiles. Khazari fighters, trained by Iran are deployed there, as well as Russian forces (they recently took another casualty, allegedly killed by IED while guarding a humanitarian convoy but in all likelihood he was operating a BM-27 MLRS in support of the SAA forces). Meanwhile the Russian airforce is flying interdiction against rebel vehicles trying to break through to Aleppo. It's not 100% clear, but it appears that the road to Aleppo is not under direct SAA control, but is effectively shut down for rebel traffic.

In the background of this, Russia and Turkey have made nice. The pilot who shot down the Russian bomber is accused of being part of the coup, the prime minister who claimed he ordered the shoot-down has stepped down, and Erdogan has apologized (if a bit cleverly worded) for the shoot down. Russian tourists are returning to Turkey. It remains to be seen how well this works in the light of events around Aleppo. Have the Turks really given up on their Syrian ambitions?

Finally Russia has suggested that counter-terrorist efforts in Syria ought to be carried out jointly by Russia and the US. It strikes me as almost a carrot and stick approach, between the bombing of that base, and this offer. Reading between the lines, if the US wants their proxy forces safe from Russian airstrikes, they need to be on the same side as the pro-Assad coalition.
This is especially interesting in light of the mistaken strike in Manbij, where US bombs killed scores of civilians. Following which representatives of the moderates called for the US to halt conducting strikes against ISIS, pending an investigation.
