# Changelog
This is the log for changes to the HEJ program. Further changes to the HEJ API
are documented in `Changes-API.md`. If you are using HEJ as a library, please
also read the changes there.
## Version 2.X
### 2.X.0
* Resummation for W bosons with jets
- New subleading processes `extremal qqx` & `central qqx` for a quark and
anti-quark in the final state, e.g. `g g => u d_bar Wm g` (the other
subleading processes also work with W's)
- `HEJFOG` can generate mutliple jets together with a (off-shell) W bosons
decaying into lepton & neutrino
* Allow multiplication and division of multiple scale functions e.g.
`H_T/2*m_j1j2`
* Print cross sections at end of run
* Follow HepMC convention for particle Status codes: incoming = 11,
decaying = 2, outgoing = 1 (unchanged)
* Partons now have a Colour charge
- Colours are read from and written to LHE files
- For reweighted events the colours are created according to leading colour in
the FKL limit
* Allow changing the regulator lambda in input (`regulator parameter`, only for
advanced users)
* Use `git-lfs` for raw data in test (`make test` now requires `git-lfs`)
* Added support to read `hdf5` event files suggested in
[arXiv:1905.05120](https://arxiv.org/abs/1905.05120) (needs
[HighFive](https://github.com/BlueBrain/HighFive))
+* Support input with avarage weight equal to the cross section (`IDWTUP=1 or 4`)
## 2.0.5
* Fixed event classification for input not ordered in rapidity
### 2.0.4
* Fixed wrong path of `HEJ_INCLUDE_DIR` in `hej-config.cmake`
### 2.0.3
* Fixed parsing of (numerical factor) * (base scale) in configuration
* Don't change scale names, but sanitise Rivet output file names instead
### 2.0.2
* Changed scale names to `"_over_"` and `"_times_"` for proper file names (was
`"/"` and `"*"` before)
### 2.0.1
* Fixed name of fixed-order generator in error message.
