The old CMBR.....it's a measure of the Cosmic Microwave Background (CMB) Radiation that provides the temperature signature that GR theory scientists consider is the leftover heat from the BB. But ESA's Planck satellite provided the most detailed CMB map ever in 2013, and some anomalies appear that challenge the standard model.

Okay, here is a big problem.
There is NO "old CMBR"
First is was predicted by the Big Bang theory.
Then it was actually discovered by Bell Labs doing work on Microwaves, but they didn't know until later the physicists has predicted it with the big bang theory.
Arno Penzias and Robert Wilson
Bell Labs, Holmdel, NJ
The Large Horn Antenna and the Discovery of Cosmic Microwave Background Radiation
"As part of the APS historic sites initiative, on December 9, 2008, APS Vice-President Curtis Callan presented a plaque to Bell Labs to commemorate the discovery of the Cosmic Microwave Background Radiation (CMB) that provided evidence for the Big Bang. Bell Labs radio astronomers Arno Penzias and Robert Wilson were using a large horn antenna in 1964 and 1965 to map signals from the Milky Way, when they serendipitously discovered the CMB. As written in the citation, "This unexpected discovery, offering strong evidence that the universe began with the Big Bang, ushered in experimental cosmology." Penzias and Wilson shared the Nobel Prize in Physics in 1978 in honor of their findings.
The CMB is "noise" leftover from the creation of the Universe. The microwave radiation is only 3 degrees above Absolute Zero or -270 degrees C,1 and is uniformly perceptible from all directions. Its presence demonstrates that that our universe began in an extremely hot and violent explosion, called the Big Bang, 13.7 billion years ago."
"
In 1960, Bell Labs built a 20-foot horn-shaped antenna in Holmdel, NJ to be used with an early satellite system called Echo. The intention was to collect and amplify radio signals to send them across long distances, but within a few years, another satellite was launched and Echo became obsolete.2
With the antenna no longer tied to commercial applications, it was now free for research. Penzias and Wilson jumped at the chance to use it to analyze radio signals from the spaces between galaxies.3 But when they began to employ it, they encountered a persistent "noise" of microwaves that came from every direction. If they were to conduct experiments with the antenna, they would have to find a way to remove the static.
Penzias and Wilson tested everything they could think of to rule out the source of the radiation racket. They knew it wasn’t radiation from the Milky Way or extraterrestrial radio sources. They pointed the antenna towards New York City to rule out "urban interference", and did analysis to dismiss possible military testing from their list.4
Then they found droppings of pigeons nesting in the antenna. They cleaned out the mess and tried removing the birds and discouraging them from roosting, but they kept flying back. "To get rid of them, we finally found the most humane thing was to get a shot gun…and at very close range [we] just killed them instantly. It’s not something I’m happy about, but that seemed like the only way out of our dilemma," said Penzias.5 "And so the pigeons left with a smaller bang, but the noise remained, coming from every direction."6
At the same time, the two astronomers learned that Princeton University physicist Robert Dicke had predicted that if the Big Bang had occurred, there would be low level radiation found throughout the universe. Dicke was about to design an experiment to test this hypothesis when he was contacted by Penzias. Upon hearing of Penzias’ and Wilson’s discovery, Dicke turned to his laboratory colleagues and said "well boys, we’ve been scooped."7
Although both groups published their results in Astrophysical Journal Letters, only Penzias and Wilson received the Nobel Prize for the discovery of the CMB.
The horn antenna was designated a National Historic Landmark in 1990. Its significance in fostering a new appreciation for the field of cosmology and a better understanding of our origins can be summed up by the following: "Scientists have labeled the discovery [of the CMB] the greatest scientific discovery of the 20th century."8

Then came the BOOMERanG experiment
Then Cobe
"NASA's COBE (Cosmic Bakground Explorer) satellite was developed to measure the diffuxe infrared and cosmic microwave background radiation from the early Universe to the limits set by our astrophysical environment."
COBE - Cosmic Background Explorer
Then Wmap
Wilkinson Microwave Anisotropy Probe
Wilkinson Microwave Anisotropy Probe (WMAP)
Then Planck
Planck / Space Science / Our Activities / ESA
All taking better measurements and using better technology to get finer detail.
"Radiation that provides the temperature signature"
Its gives that data and a lot more!
"that GR theory scientists consider is the leftover heat from the BB"
No they don't considered it, they know it for a fact. Its the relic light frozen in time of the BB.

When this cosmic background light was released billions of
years ago, it was as hot and bright as the surface of a star.
The expansion of the universe, however, has stretched space by a
factor of a thousand since then. The wavelength of the light has
stretched with it into the microwave part of the electromagnetic
spectrum

"But ESA's Planck satellite provided the most detailed CMB map ever in 2013, and some anomalies appear that challenge the standard model. "
Yes and they also supported inflation and there are anomalies they need to figure out, but they were also looking for multiverses in the heat signature and have not found them, in fact the case for some models got worse. Penrose also looked for a signature and did not find it yet.
One thing to take note of is that is the light of the big bang frozen in time. As the universe expands at some point you won't be able to study it either. The universe is expanding faster then light.
The inflation model goes more back to a singularity perhaps, but that still doesn't rule out multiverses.
and you did notice the title?
New data from the Planck satellite suggests very good news for proponents of the standard Big Bang cosmological model of the universe.
