.. _release-notes: Release notes ============= These release notes record the changes made in all major and patch releases of |Gromacs|. Major releases contain changes to the functionality supported, whereas patch releases contain only fixes for issues identified in the corresponding major releases. Two versions of |Gromacs| are under active maintenance, the 2021 series and the 2020 series. In the latter, only highly conservative fixes will be made, and only to address issues that affect scientific correctness. Naturally, some of those releases will be made after the year 2020 ends, but we keep 2019 in the name so users understand how up to date their version is. Such fixes will also be incorporated into the 2021 release series, as appropriate. Around the time the 2022 release is made, the 2020 series will no longer be maintained. Where issue numbers are reported in these release notes, more details can be found on the `issue tracker`_ at that issue number. |Gromacs| 2021 series --------------------- .. todolist:: Patch releases ^^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2021/2021.3 2021/2021.2 2021/2021.1 Major release ^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2021/major/highlights 2021/major/features 2021/major/performance 2021/major/tools 2021/major/bugs-fixed 2021/major/deprecated-functionality 2021/major/removed-functionality 2021/major/portability 2021/major/miscellaneous |Gromacs| 2020 series --------------------- Patch releases ^^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2020/2020.6 2020/2020.5 2020/2020.4 2020/2020.3 2020/2020.2 2020/2020.1 Major release ^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2020/major/highlights 2020/major/features 2020/major/performance 2020/major/tools 2020/major/bugs-fixed 2020/major/deprecated-functionality 2020/major/removed-functionality 2020/major/portability 2020/major/miscellaneous |Gromacs| 2019 series --------------------- Patch releases ^^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2019/2019.6 2019/2019.5 2019/2019.4 2019/2019.3 2019/2019.2 2019/2019.1 Major release ^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2019/major/highlights 2019/major/features 2019/major/performance 2019/major/tools 2019/major/bugs-fixed 2019/major/deprecated-functionality 2019/major/removed-functionality 2019/major/portability 2019/major/miscellaneous Older (unmaintained) |Gromacs| series ------------------------------------------------------- |Gromacs| 2018 series --------------------- Patch releases ^^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2018/2018.7 2018/2018.6 2018/2018.5 2018/2018.4 2018/2018.3 2018/2018.2 2018/2018.1 Major release ^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2018/major/highlights 2018/major/features 2018/major/performance 2018/major/tools 2018/major/bugs-fixed 2018/major/removed-features 2018/major/portability 2018/major/miscellaneous |Gromacs| 2016 series --------------------- Patch releases ^^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2016/2016.5 2016/2016.4 2016/2016.3 2016/2016.2 2016/2016.1 Major release ^^^^^^^^^^^^^ .. toctree:: :maxdepth: 1 2016/major/highlights 2016/major/new-features 2016/major/performance 2016/major/tools 2016/major/bugs-fixed 2016/major/removed-features 2016/major/miscellaneous .. toctree:: :maxdepth: 1 older/index
