Fix the validity of TRef after the first ProcessID is full.
Add support for LZ4 compression.
Properly handle 'cycle' number larger than 32767 by rounding to zero rather than a negative number.
Properly propagate errors in OpenExcessFiles in TFileMerger (ROOT-8167).
Fix TText copy constructor as requested here.
In TMarker3DBox when a box marker has a size equal to zero it is not painted. Painting it produced a dot with the X11 backend.
TObject instances allocated as part of an array and made part of a collection, as for example the TCanvas instances into the global list of instances, are not longer deleted if the content of the collection is deleted. Technically the element of the array are now treated by collections as if they have been allocated on the stack. This fixes the issue described at (ROOT-7846).
Resolve an issue when space is freed in a large ROOT file and a TDirectory is updated and stored the lower (less than 2GB) freed portion of the file (ROOT-8055).
Fix (ROOT-7423) TTreeCache may not stop the learning phase when asynchronous prefetching is enabled.
Fix the issue described in the (following forum post(https://root.cern.ch/phpBB3/viewtopic.php?t=20269)), where a some order of calls to TTree::Scan and TTree::Write resulted in invalid output.
Repair setting the branch address of a leaflist style branch taking directly the address of the struct. (Note that leaflist is nonetheless still deprecated and declaring the struct to the interpreter and passing the object directly to create the branch is much better).
TGraph::GetHistogram() was resetting the TimeDisplay attribute of axis. The problem was reported here.
When painting a TH3 as 3D boxes, TMarker3DBox ignored the max and min values specified by SetMaximum() and SetMinimum(). The problem was reported here.
When using time format in axis, TGaxis::PaintAxis() may in some cases call strftime() with invalid parameter causing a crash. This problem was reported here.
Make sure that TLatex text strings containing "\" (ie: rendered using TMathText) produce an output in PDF et SVG files.
New version of libpng (1.2.55) as requested here.
Fix (ROOT-7703) This restores the behavior of Locate() to that found with TXNetFileStager: Rather than return only the xrootd server's reply, the endpoint hostname is looked up and Locate() returns the full url, including the path.
Fix (ROOT-7809) Returns an error for a redirect which does not specify the new URI, rather than going into a loop.
Fix (ROOT-7817) Avoid a crash under some circumstances when trying to open an invalid path.
Fix TPgSQLStatement::SetBinary to actually handle binary data (previous limited to ascii).
