Myanmar's junta has claimed to have pardoned and released more than 23,000 prisoners - but it is not known if the figure includes pro-democracy activists detained in the wake of February's coup.
The release was announced to mark the new year holiday.
State broadcaster MRTV said Myanmar's military leader Senior General Min Aung Hlaing pardoned the 23,047 prisoners, including 137 foreigners who will be deported.
He also reduced sentences for others.
Early prisoner releases are customary during major holidays, but this is the second time the ruling junta has done so since it ousted the elected government of Aung San Suu Kyi, triggering daily protests, arrests and deaths by security forces.
According to the Assistance Association for Political Prisoners, which monitors casualties and arrests, government forces have killed at least 726 protesters and bystanders since the takeover.
The group says 2,728 people, including Ms Suu Kyi, are in detention.
Following the release of more than 23,000 convicts to mark Union Day on 12 February, there were reports on social media that some were recruited by the authorities to carry out violence at night in residential areas to spread panic.
Some areas responded by setting up their own neighbourhood watch groups.
The military said it staged the coup because a November election won by Ms Suu Kyi's party was rigged - an assertion dismissed by the election commission.
