Update.
Aleppo
Significant gains made around Kuweiris, a slow push westward through the Chemical plant, and several towns and villages to the south east, have fallen to the SAA. In the south-west of Aleppo, a rebel counter-offensive stemmed the Iranian and Hezbollah push for the Damascus-Aleppo highway, but after reinforcement arrived on Dec 7th, government forces are on the offensive again. The goal is of course taking the highway, and destroying as many rebel forces in the fight as they can.
North of Aleppo a brief counter-attack by rebels against ISIS pushed them back somewhat, but it didn't last. Kafra, which fell to ISIS iirc two days ago. ISIS is clearly pushing for Azaz.
Latakia
Reports that Salma is surrounded, or almost so, are untrue. The SAA is still pushing north, slowly, mainly to the east and west of Salma.
Hama-Homs-Palmyra
The front has stabilized, and while the government offensive failed, the rebels couldn't counter-attack. They had to redeploy their reserves to Aleppo.
The last few rebels in the city agreed to leave, provided they were given a safe corridor to exit with their weapons. They are now in the rebel held area around Ar-Rastan, where government troops are trying but so far failing to open the Homs-Hama highway.
At Palmyra, Assad's forces have reached the approaches to it, and it's eventual liberation will be significant, but it doesn't look likely right now.
Damascus-DeZ-Deraa
Little changes in any of them, except some tiny gains in Damascus area, literally single houses or occasionally blocks.
Kurds
The Kurds have cut a major highway from Iraqi Mosul to Syria, and are pushing for Shaddadi. Their rapid gains threaten ISIS ability to move troops between Iraq and Syria.

Meanwhile Iraq is preparing for the Assault of Ramadi, having given final notice to civilians to leave. They're slowly clearing outer settlements around it.
They've also joined Russia's accusation, saying that most of ISIS oil goes through Turkey. Meanwhile Turkey doesn't expect to withdraw their trainers from Iraq, though it seems they've halted sending more. Even the US has said that they don't support the Turkish action.

Russian jets are reported to be flying over Syria army positions to protect them from coalition air strikes. Meanwhile Syria called the strike an act of aggression
Personal comment, I think this has been overstated. It's likely some fighters flew over the Deyr-ez-Zor camp after the air strike, but Russia doesn't have enough planes, especially with the need to escort their own strikers, to do what this article claims.
