This file summarizes STA API changes for each release.
Release 3.1.0 2026/03/25
------------------------
OpenSTA now uses std::string and std::string_view instead of const char *.
Lookup funtions such as Network::findPin use std::string_view that accept
a const char *, std::string, or std::string_view caller argument.
2026/03/19
----------
LibertyCell::footprint() returns const std::string& instead of const char*.
LibertyCell::userFunctionClass returns const std::string& instead of const char*.
The Sdc, Liberty, ConcreteLibrary, ConcreteNetwork classes have been updated to
use std::string and std::string_view instead of const char *. std::string_view
is used when the lifetime of the string argument is only while the function is
called. std::string is used when the string value outlives the function call
because it is stored in data structures.
The LibertyPort functions
relatedGroundPin
relatedPowerPin
are renamed to
relatedGroundPort
relatedPowerPort
and return LibertyPort's instead of strings.
2026/03/12
----------
@ -37,7 +64,7 @@ stdstrPrint, strintPrint, stringAppend have been removed. Use sta::format.
reportLineString is now reportLine
Release 3.0.0 2025/01/03
Release 3.0.0 2026/01/03
