+## Version 1.1.0
+
+This update to cppdlr adds significant new functionality, including symmetrized DLR grids, and improvements to ensure accuracy of DLR expansions in L^2(tau) norm (both described in the updated documentation).

+
+### New features
+* Symmetrized DLR grids, w/ tests to compare symmetrized/non-symmetrized grids
+* Documentation updates: symmetrized grids, discussion of error
+* Imaginary time quadrature weighting for DLR frequency selection to ensure accuracy in L^2(tau) norm, updated tests accordingly
+* Function to compute imaginary time inner products of DLR expansions
+* Program to print DLR ranks for various Lambda
+* Tests to interpolate in imag time and measure error in imag freq, and vice versa
+* Unit tests print errors via fmt
+* Implementation of symmetrized pivoted Gram-Schmidt with tolerance or rank specified
+* Print warning if user chooses epsilon dangerously small
+* Expose fermionic and bosonic Matsubara frequency kernels to user directly
+
+### Bug fixes
+* Fixed bosonic kernel at i*om_n=0
+* Fixed bug involving non-contiguous views in vals2coefs implementations
+* Fixed bug in error checking of fine discretization of imag time kernel in geterr_k_it
+* Fixed uninitialized niom value in dlr_imfreq constructor
+* Fixed range bug in imtime_ops.interp_matrix_sym_bos
+
+### Optimizations
+* Make complex copy of it2cf.lu in imtime_ops constructor to avoid on-the-fly copies
+* imtime_ops::convolve optimizations; use nda::matmul when possible
+
+### Other changes
+* Various code simplifications
+* Test tolerance adjustments
+* References to cppdlr preprint in documentation and readme
+
+### General
+* Remove redundant sys.path insertion in conf.py.in
+* Remove pip3 install command from Dockerfile
+* Update requirements.txt with dependencies for documentation builds
+* Disable notes about C++ ABI changes when using gcc
+* Fix compiler warning, use abs from std namespace
+* Update macos build instructions in Jenkinsfile and build.yml
+* Set proper GNU install dirs also in env vars file
+* Fix typo in Jenkinsfile
+* Bump actions/checkout from 2 to 4
+* Fix settings environment variables
+* Allow manual dispatch and triggering action from other workflow
+* Prevent unintentional parallelization in OpenBLAS
+* Use ccache to speed up compilation
+* Remove numpydoc sources from doc/sphinxext
+* Raise shm size for docker run commands to comply with mkl requirements
+* Skip image and binary files in replace_and_rename
+* Use python3 instead of python2 in replace_and_rename.py script
+
+
+### cmake
+* Bump version number to 1.1.0
+* Bump Version number to 3.3
+* Remove C as a project language
+* Update top-level CMakeLists.txt file with latest app4triqs skeleton

+* Do not define DEBUG macros for RelWithDebInfo builds
+* Correct target file inclusion PATH to be absolute
+* Only use GNUInstallDirs for LIBDIR
+* Fix target inclusion directory to use GNUInstallDirs
+* Use unstable branch of cpp2py
+* Minor improvements in top-level CMakeLists.txt
+* Consistently use GNUInstallDirs for install commands
+* Use GNUInstallDirs to obtain installation directories
+* Set policy 114 to new
+* Set policy CMP0144 to new
+* Run Debug checks also in RelWithDebInfo build mode
