This year's festival will also be more accessible than before.
Some live performances will come with features such as audio description and open captioning. All videos on demand will have closed captions. A quiet space - where people can retreat to if they feel overstimulated - will be provided near each performance venue.

The threat of climate change looms large in this play by Australia-based playwright Andrew Sutherland.
It consists of several narratives - a same-sex couple in a rocky relationship, another couple who are newly in love, and a storyline where a goddess searches for her son and laments her impending death. Otters, seagulls and sea turtles make frequent appearances.
"What if we cross that line as we go towards that unimaginable thought of extinction?" asks director Koh Wan Ching.
"How do we hold on to hope? What is hope when we face such imminent destruction or erasure?"
The work was first performed in 2019 by eight students from the Intercultural Theatre Institute and two guest artistes, to positive reviews.
The latest staging, which Koh, 40, describes as "more streamlined and quieter", features actors Grace Kalaiselvi, Irfan Kasban, Jeramy Lim, Liz Sergeant Tan and Shahid Nasheer. They double as human and animal characters.
"You see a much clearer interconnection between the human and animal worlds," Koh adds.
The production was complemented by two public workshops that ended recently.
Intimate Catastrophes, which Sutherland ran on Zoom, looked at various ways of responding to ecological phenomena in writing.
In the other workshop, Everything Is Connected - On Devising, Koh spoke about how she works with environmental concerns in her theatre-making.
What worries her most about the climate crisis?
"I feel there is not enough work being done on mitigation," she says. "How can we change the way we are functioning?
"Can we slowly transition our economy towards a more care-based one, one that is less focused on production and economic development?"
Theatre, too, has a role to play.
"We can't solve problems, but what we can do is get people to come together and think about it.
"The thing about theatre is to not offer solutions, but acknowledge that these issues are complex."
