XY Chelsea is being directed by British filmmaker Tim Travers Hawkins (1000 Voices) and executive produced by Oscar victor Laura Poitras (Citizenfour, Risk), with the filmmakers having been granted exclusive rights to Manning's story and having had unprecedented access to her team for two years as they fought for her release.
Until Manning's appeal of her court martial conviction is resolved, the whistleblower will remain a member of the USA military.
Without Obama's parting gift, Manning would have remained behind bars until 2045, after a 35-year sentence.
"I think that it is great that Chelsea Manning is going to be able to live her life authentically and she should most definitely be allowed to do so, but that does not excuse past behaviors that put lives at risk and put her into prison in the first place", Angelo said.
"For the first time, I can see a future for myself as Chelsea".
"In the end, it was Manning who was punished, not those at the highest levels of the United States government, whose actions were exposed", Rattansi said.
The possibility that Manning could become a new, prominent face in the gay, lesbian, bisexual and transgender rights movement has sparked concern among some, however.
A fundraising page set up by friends and family in February to assist Manning after her release has raised $150,000. I am forever grateful to the people who kept me alive, President Obama, my legal team and countless supporters. But they denied a plea to let her grow out her hair, which, according to photos posted on the GoFundMe site, remains trimmed into a side-swept, masculine cut.
Manning's attorneys disclosed in September that she had been approved for gender reassignment surgery. About the time of the decision, Manning wrote a column that criticized Mr. Obama's record.
On Monday, Chelsea Manning took to Twitter to announce that only two more days were remaining "until the freedom of civilian life".
Arrested in 2010, Manning had been serving in Iraq and was known as Bradley Manning.
Al Jazeera's Shihab Rattansi, reporting from Quantico, Virginia, where Manning was detained at a US Marines base for three years, said her leaks "revealed the normality of lies and brutality" by the US government. "Now hunting for private #healthcare like millions of Americans". "I can imagine surviving and living as the person who I am and can finally be in the outside world", she said in a written statement.
