-RELEASE SCHEDULE
-----------------
-
-![HDF5 release schedule](doc/img/release-schedule.png) 
-
-HDF5 does not release on a regular schedule. Instead, releases are driven by
-new features and bug fixes, though we try to have at least one release of each
-maintenance branch per year. Future HDF5 releases indicated on this schedule
-are tentative.
-
-**NOTE**: HDF5 1.12 is being retired early due to its incomplete and incompatible VOL
-layer.
-
-| Release | New Features |
-| ------- | ------------ |
-| 1.8.23 | last HDF5 1.8 release |
-| 1.10.10 | CVE fixes, performance improvements, H5Dchunk\_iter() |
-| 1.12.3 | CVE fixes, performance improvements, H5Dchunk\_iter(), last HDF5 1.12 release |
-| 1.14.1 | selection I/O with datatype conversion |
-| 2.0.0 | TBD |
-| TBD | VFD SWMR |
-

-in which a feature is introduced may change.
