A complete rewrite of versions in Rust has been release in

Versions is an open source (GPL v3) software that checks releases and versions of your favourite programs through RSS or Atom feeds and tells you which one has been released since last check.

It can check projects from :

  • (FreeBSD packages)
  • sourcehut forge
  • gitlab forge

Projects must be added to a YAML file (named by default ~/.config/versions/versions.yaml). One can use --file=FILENAME option to specify an alternative YAML file. The structure of this YAML file is explained below.

Versions uses and produces text files. Those files are cache files written into ~/.local/versions directory. *.cache are cache files containing the project list and their associated version (the latest). *.feed are information feed cache files containing on each line the latest parsed post of the feed.

YAML file structure

  url: "https://the.url/to/theglobalfeed"
  type: list
    - list
    - of
    - projects

  url: "{}.atom"
  type: byproject
    - list
    - name: of
      regex: '([\d.]+)'
      entry: last checked
    - projects

There is two types of sites :

  • 'list': The site has one feed with all projects in it such as or
  • 'byproject": The site gives access to one feed per project. brackets '{}' represents the name of the project as found in the 'project' list. Those projects can be listed directly or can take options. In the later case you have to name the project and then you can specify either a regex or an entry type option: regex is used to determine version number and entry is used to determine if versions has to print the latest entry (default behavior) or all entries from the "last checked" time.

A real life example file is provided: versions/versions.yaml


Installation of versions is not mandatory and you can invoke it directly from the command line provided you have already installed its requirements.


In pypi the project is named program_versions but is still invoked by the command versions :

$ sudo pip install program_versions
$ versions -v

From source

$ git clone
$ cd versions
$ sudo pip install -r requirements.txt
$ sudo python install
$ versions -v

Tip : One may want to test versions without messing its installation and may use miniconda to do so.


./ should be enough to bring you the list of updated programs since last run. To verify each day one can use the following command in a persistent terminal (tmux, screen…):

$ watch -n 86400 ./
  • Option -h or --help will give you some help.
  • Option -v or --version will tell you the version you have.
  • Option -l or --list-cache prints the content of the local cache (ie latest known versions).
  • Option -f FILENAME or --file FILENAME ease usage of different YAML configuration files.
  • Option -d or --debug runs doctests and prints information about what's going on in the program.
