-- [[PR 114]](https://github.com/parthenon-hpc-lab/athenapk/pull/109) Bump Parthenon to latest develop (2024-05-29)
+- [[PR 114]](https://github.com/parthenon-hpc-lab/athenapk/pull/114) Bump Parthenon 24.08 and Kokkos to 4.4.00
   - Changed signature of `UserWorkBeforeOutput` to include `SimTime` as last paramter
   - Fixes bitwise idential restarts for AMR simulations (the derefinement counter is now included)
   - Order of operations in flux-correction has changed (expect round-off error differences to previous results for AMR sims)
+  - History outputs now carry the output block number, i.e., a file previously called parthenon.hst might now be called parthenon.out1.hst
+  - History outputs now contain two additional columns (cycle number and meshblock counts), which changes/shifts the column indices (hint: use the column headers to parse the contents and do not rely on fixed indices as they may also vary between different pgen due to custom/pgen-dependent content in the history file)
 - [[PR 97]](https://github.com/parthenon-hpc-lab/athenapk/pull/97)
   - Removes original `schure.cooling` cooling curve as it had unknown origin.
   - To avoid confusion, only cooling table for a single solar metallicity are supported
