 ## SPAdes 4.0.0, 3 June 2024
+- SPAdes now supports NCBI SRA files as input;
+- Reworked and improved documentation: [ablab.github.io](https://ablab.github.io);
+- [PathRacer](https://ablab.github.io/spades/pathracer.html) - a tool for mapping HMMs to assembly grpah - is now released as a part of SPAdes package;
+- [BinSPreader](https://ablab.github.io/spades/binspreader.html) (metagenomic binning refiner) is also released inside SPAdes package;
+- New [gfa-split tool](https://ablab.github.io/spades/standalone.html#graph-splitting) for splitting assembly graph into components;
+- New [wasterwaterSPAdes](https://ablab.github.io/spades/running.html#-sewage) mode for quantitative assessment of
+SARS-CoV-2 strains in waste water samples;
 - Python3.8 is now a minimal required version, python2 is deprecated;
-- SPAdes now supports SRA files as input;
-- PathRacer is now released as a part of SPAdes package;
-- [BinSPreader](https://ablab.github.io/spades/binspreader.html) is also along with SPAdes package;
-- New gfa-split tool;
-- New [wasterwaterSPAdes](https://ablab.github.io/spades/running.html#-sewage) mode;
 - Native support for running on Apple Silicon processors;
 - Native support for running on aarch64/linux;
-- Binaries are now built using ManyLinux 2.28;
-- Parallel & improved GapCloser algorithm;
-- Faster graph simplification;
-- Allow external projects integration with SPAdes;
-- Use SPOA for long reads consensus;
+- Binaries are now built using [ManyLinux 2.28](https://peps.python.org/pep-0600).
+SPAdes binaries should be compatible with systems using glibc 2.28 and newer including
+ALT Linux 10+, RHEL 9+, Debian 11+, Fedora 34+, Mageia 8+, Photon OS 3.0 with updates, Ubuntu 21.04+.
+In case of any problems we recommend building from sources.
+- Allow external projects integration with SPAdes.
+Projects could be integrated directly with SPAdes codebase or use SPAdes libraries.
+Contact us for technical details.
 - SPAdes outputs assembly graph in GFA v1.2 format by default, older v1.1 format is also available;
 - SPAdes tags circular paths in assembly graph with `TP:Z:circular` flag;
+- SPAdes internally supports 0 bp overlap graph and graphs with variable overlaps in vertices
+(e.g. multiplex de Bruijn graphs). Some SPAdes standalone tools allow use of such graphs as input.
 - SPAdes now uses `zlib-ng` for faster gzip decompression of input files;
 - Fixed compilation with gcc 13;
+- Use SPOA for long reads consensus;
+- Parallel & improved GapCloser algorithm;
+- Faster graph simplification;
 - Removed deprecated truSPAdes functionality;
-- Reworked and improved documentation;
 - Lots of other fixes and improvements.
