+## Utilities
+
+- Bug #1468: LuaOptionFile wasn't robust enough and couldn't interpret some files if two closing braces were on the same line. The 
+facility to identify entry keys has been entirely rewritten and seems to work in any case (I did my best to write all the edge cases I could
+think of in the test suite).
+
+- Support #1470 - Feature #279:  Refactor PrintContainers facilities: there are now only two functions (one for tuple and another for other 
+containers). Policies aere provided to handle the different cases (including associative containers).
+- Support #1469: One of the policy mentioned in #1470 enables to print content of a container of std::variant (provided the types within the 
+variant are printable).
+- Support #1467: Following #1432, there is no need to keep track of the LuaOptionFile used to interpret input data file. 
+
+## Core
+
+- Feature  #1466:  Separate RAII initialization of PETSc and Mpi from the rest of MoReFEMData. Thus several InputData may be initialized
+within a single program.
+- Feature #1465:  Add the possibility to write down the content of InputData. Will be used in #1443
+- Feature  #1315:  Implement the possibility to update correctly all the comments of a Lua file (consequence of #1465). Lua files of embedded
+models have been updated with this new functionality.

 ## Tests
 
 - Bug #1461: Due to a git mishap, test about PetscVectorIO was buggy (the fix to the bug was unwittingly overwritten...)
 - Bug #1464: A test (Utilities/Now) could fail due to racing condition.

+- Support #1471:  Work around a Doxygen issue (on VM only): three warnings appear for no reason (a function signature is truncated and 
+thus Doxygen can't connect the dot with the provided parameter).
