Summary of what's been discussed.


Proposal #1) Original[edit]

The original requested way that it should work is illustrated in this example:

<compatibility>
  <version>1.5</version>
  <version>2.5</version>
  <version>3.0.1</version>
  <version>4</version>
<compatibility>

Is interpretted as:

  • Joomla 1.5: compatible
  • Joomla 1.6: not compatible
  • Joomla 1.7: not compatible
  • Joomla 2.5: compatible
  • Joomla 3.0: compatible for 3.0.1 and up in the 3.0 version
  • Joomla 3.1: not compatible
  • Joomla 3.2: not compatible
  • Joomla 3.5: not compatible
  • Joomla 4:0: compatible
  • Joomla 4.1: compatible
  • Joomla 4.2: compatible
  • Joomla 4.5: compatible

Proposal #2) Composer[edit]

Others thought, we shouldn't use either of the above, but should use: Composer

Proposal #3) Remove version attribute and replace it with compatibility tag (in the below manner)[edit]

See: https://github.com/joomla/joomla-cms/issues/594

Proposal #4) Modification of Original (compare with #1) after adding an exclude attribute/parameter[edit]

After adding an exclude attribute/parameter, the proposal became:

Whatever version is given, it's interpreted as "and up until the next major version". (This can be overriden with exclude_only="true" or include_only="true" or from="version#here" to="version#here")

For example:

<compatibility>
  <version>3.5</version>
  <version>4.2.2</version>
  <version>6</version>
  <version exclude_only="true">6.1.3</version>
  <version>7</version>
  <version exclude_only="true">7.0</version>
  <version include_only="true">8.1</version>
  <version from="9.0.8" to="9.0.99" />
  <version exclude_only="true">10</version>
<compatibility>

is interpreted as:

  • Joomla 3.0: not compatible
  • Joomla 3.1: not compatible
  • Joomla 3.2: not compatible
  • Joomla 3.5: compatible
  • Joomla 4.0: not compatible
  • Joomla 4.1: not compatible
  • Joomla 4.2: compatible from 4.2.2 and up
  • Joomla 4.5: compatible
  • Joomla 5.0: not compatible
  • Joomla 5.1: not compatible
  • Joomla 5.2: not compatible
  • Joomla 5.5: not compatible
  • Joomla 6.0: compatible
  • Joomla 6.1: compatible for all (above and below) except 6.1.3
  • Joomla 6.2: compatible
  • Joomla 6.5: compatible
  • Joomla 7.0: not compatible
  • Joomla 7.1: compatible
  • Joomla 7.2: compatible
  • Joomla 7.5: compatible
  • Joomla 8.0: not compatible
  • Joomla 8.1: compatible
  • Joomla 8.2: not compatible
  • Joomla 8.5: not compatible
  • Joomla 9.0: compatible from 9.0.8 to 9.0.99
  • Joomla 9.1: not compatible
  • Joomla 9.2: not compatible
  • Joomla 9.5: not compatible
  • Joomla 10.0: not compatible
  • Joomla 10.1: not compatible
  • Joomla 10.2: not compatible
  • Joomla 10.5: not compatible
  • Joomla 11.0: not compatible
  • Joomla 11.1: not compatible
  • Joomla 11.2: not compatible
  • Joomla 11.5: not compatible

Notes[edit]

99%-100% of the code is written for the original implementation. The getcomposer approach is not written.


The original implementation did not ask for a x.y.z version to be able to be excluded. If a feature like that is needed, e.g. <not_version>3.0.7</not_version>, it can be implemented. It's been added as <version exclude="true"></version> thus far. It's simple a place holder until the syntax is decided.
