Apache CloudStack vs HydroPortailStats
A side-by-side editorial comparison of Apache CloudStack and HydroPortailStats — release velocity, themes, recent moves, and the top alternatives to consider.
Apache CloudStack vs HydroPortailStats: at a glance
What is Apache CloudStack?
CloudStack's feed shows two LTS branches maintained in parallel and little else
The visible activity on Apache CloudStack is branch maintenance across two long-term-support lines, 4.20 and 4.22. The newest tag, 4.20.3.1, carries no release notes at all — just a line stating it was tagged on a fixes branch. The most informative recent entry remains 4.22.0.1, a security release fixing seven CVEs, several of them access-control failures around backups.
What is HydroPortailStats?
France's national flood statistics, ported out of Fortran and into R.
HydroPortailStats exposes the statistical machinery behind the French HydroPortail — distribution fitting, quantile curves and their uncertainties for hydrological series. The 2025 release re-implements the HBay Fortran executable in R, adding Bayesian estimation from historical flood records with censored and interval-valued data and systematic measurement error, plus a triangular distribution and truncated random generation.

◆ Current state
The visible activity on Apache CloudStack is branch maintenance across two long-term-support lines, 4.20 and 4.22. The newest tag, 4.20.3.1, carries no release notes at all — just a line stating it was tagged on a fixes branch. The most informative recent entry remains 4.22.0.1, a security release fixing seven CVEs, several of them access-control failures around backups.
◆ Where it's heading
This feed publishes tags, not changelogs: every maintenance release points at external documentation rather than listing what changed, so direction has to be inferred from version numbers and the occasional security advisory. What can be read from it is a steady dual-branch cadence, with 4.20 and 4.22 receiving parallel maintenance and 4.22 carrying the newer feature work. The one substantive disclosure in this window, the CVE batch, clustered around backup and template permissions.
◆ Prediction
The dual-branch maintenance pattern should continue, though the feed itself will not reveal feature direction unless a security advisory forces detail into it.
HydroPortailStats
0.0INFRA · APIS
France's national flood statistics, ported out of Fortran and into R.
◆ Current state
HydroPortailStats exposes the statistical machinery behind the French HydroPortail — distribution fitting, quantile curves and their uncertainties for hydrological series. The 2025 release re-implements the HBay Fortran executable in R, adding Bayesian estimation from historical flood records with censored and interval-valued data and systematic measurement error, plus a triangular distribution and truncated random generation.
◆ Where it's heading
The package started as a straight extraction of the portal's existing functions and is now absorbing the surrounding legacy toolchain: HBay was a separate compiled program with its own config files, and this release brings both the method and its configuration format inside R. Releases are sparse — three in two years, with an eighteen-month gap before the latest — and the intervening one was CRAN paperwork.
◆ Prediction
The HBay import came with a configuration-file reader for continuity with the old executable, which suggests further legacy hydrological tooling could follow the same path; the entries name no specific next target.
