+# Release History
+
+## 0.16.2 (Yet to be released)
+
+The release combines the 0.15.1 through 0.15.4 backports with 0.16.1.
+
+* Code quality and infra changes just like 0.15.{1,2}
+* Update to a later glibc `elf.h`, just like 0.15.4
+
+## 0.16.1 (October 28, 2022)
+
+This release only fixes the incorrect reported version by the 0.16.0 release.
+
+## 0.16.0 (October 27, 2022)
+
+Changes from 0.15.3:
+
+* Add `--print-os-abi` and `--set-os-abi` options by @dmsck in https://github.com/NixOS/patchelf/pull/381
+* Sync `.note.gnu.property` to `PT_GNU_PROPERTY` by @Bo98 in https://github.com/NixOS/patchelf/pull/414
+* Rework file shifting to avoid sections crossing multiple segments by @Bo98 in https://github.com/NixOS/patchelf/pull/415
+
+(These notes are the remainder of 0.16.0 that was not backported to 0.15.3.
+Originally, 0.16.0 was branched from 0.15.0, and those changes were fresh in this release, having never been backported.)
+
+## 0.15.5 (August 12, 2025)
+
+Bugfix backports from 0.18.0:
+
+* Adjust `roundUp` for 0 as input by @cgzones in https://github.com/NixOS/patchelf/pull/466
+
+Bugfix backports from 0.17.{0, 1}:
+
+* Fix page size constants for Itanium and SPARC.
+* Fix Out-of-bounds read in the function `modifySoname` by @yairKoskas in https://github.com/NixOS/patchelf/pull/451
+
+## 0.15.4 (August 12, 2025)
+
+* Update to a later glibc `elf.h`.
+
+  This should not result in any behavioral changes, except for possibly better architecture-specific support.
+
+## 0.15.3 (August 12, 2025)
+
+This is a backport release made from the simplest fixes from 0.16.0.
+
+* Handle `glibc-hwcaps` on `ppc64le` on CentOS/RHEL/Rocky 8 for `tests/replace-add-needed.sh` (fixes #406) by @robert-scheck in https://github.com/NixOS/patchelf/pull/407
+* Fix Out-of-bounds read in the function `modifyRPath` by @xiaoxiaoafeifei in https://github.com/NixOS/patchelf/pull/419
+* Fix out of bounds access when increasing program header table by @Bo98 in https://github.com/NixOS/patchelf/pull/411
