Thailand's army says it has now released 124 people, including politicians and activists, who were taken into custody after the coup.
An army spokesman said a total of 253 people had been summoned. Fifty-three did not report and 76 were in custody.
Conditions for the release appear to include agreeing to avoid political activity and informing the army of travel, a BBC correspondent said.
Coup leaders, who took power last week, received royal endorsement on Monday.
Thailand's former prime minister, Yingluck Shinawatra, has been released but remains under some restrictions.
