Primer3 0.4.0 Free

For years, Primer3's most stable version was 1.1.4, which relied on an outdated thermodynamic model (Breslauer et al., 1986) and lacked support for degenerate primers or 3'-end stability constraints. The 2.x series introduced SantaLucia’s unified thermodynamic parameters but was plagued by inconsistent API changes.
