I am a bit more in touch with all these terminologies, having received my liberal arts degree in recent years. It is the newest buzzword for pushing for a de-europeanization of the classroom curriculum. It goes beyond truth and reconciliation with First Nations past and ongoing trauma. It is about desiring the systematic removal or whitewashing of Western-based histories and knowledge, since it is oppressive and inherently racist, in favour of some combination of secular internationalist education, with an emphasis on "different truths" not derived through western methods. See bolded below:
"CIARS is pleased to announce that it is holding its X1 Decolonizing Conference for critical dialogues on the theme of “Dialoguing and Living Well Together: Decolonization and Insurgent Voices”. Using a Decolonizing perspective, the conference hopes to explore new meanings of “living well together” outside of White mythology (in Derrida’s terms) and the capitalist paradigm.
We ask: how do we bring non-Western epistemologies to a terrain that has existed through a long-exercised White Mythology? What Indigenous experiences speak to the possibility of living well together in new futures? What additional dimensions of the above can be gleaned from the constant mobility of bodies, identities, subjectivities and relations?"

Which I think is bollocks, given the indisputable contribution to world knowledge that has come from the West, and that the proponents have no intention of switching our curriculum to learning about Chinese civilization and Confucianist epistemology if their thought-process were for a moment entertained.
These people just hate the Western society that they live in, that much is obvious.
Detailed description of that conference is available here and they have no qualms in describing our Western civilization as "sickening" and "bloodthirsty". These guys are 5th columnists that have a luxury of living in a western style liberal constitutional capitalist democracy that protects their rights and freedoms and even grants government funding for a platform to share their ghastly ideas.

An aside comment, I really think their original premise as it relates to Truth and Reconciliation is faulty to begin with. The goal should not be the removal of eurocentric curriculums. It should be the integration of First Nations culture, history and knowledge into our curriculum. New Zealand is the model that should be followed, not South Africa.
