## 2026-02-25 Vladimir Ivanchenko (particles-V11-03-02)
- Attempt to fixed data race in ion creation (Bugzilla #2680) by extention
of excited isomer name from 3 to 5 digits after dot.
## 2026-01-14 Shogo Okada
- Fixed energy conservation in G4MuonDecayChannel (Bugzilla #2678).
## 2025-11-4 Shogo Okada (particles-V11-03-01)
- Scanned all mesons and baryons, including their resonances, to compare their
particle properties with PDG-2025. Then, updated mass, decay width, and

// Fixed energy conservation in G4MuonDecayChannel (Bugzilla #2678):
// Corrected EMax definition to parentmass/2 and applied standard relativistic
