[VOTE] Release Apache DataSketches-cpp-5.3.0-rc1
Hello Apache DataSketches PMC and Community,
This is a call for a vote to release Apache DataSketches-cpp
candidate version 5.3.0-rc1
Changes from the previous release (5.2.0, January 2025):
*New features:*
- Theta sketch: optional trim flag on update_theta_sketch::compact();
lg_k = 4 is now accepted, matching Java
- Count-Min sketch: serialize_to() for caller-supplied sinks;
get_hashes() no longer allocates
- Frequent items sketch: reset()
- t-digest: const iterator over the centroids
*Bug fixes and Java compatibility:*
- Stricter validation of serialized sketches: malformed or truncated
input is rejected with an exception (Bloom filter, CPC, Count-Min,
HLL, KLL, Quantiles, REQ, Theta, Tuple, VarOpt)
- HLL: fixes to the deferred KxQ rebuild and union estimate;
serialization flags aligned with Java
- Theta/Tuple: single-item flag, empty-sketch seed hash and A-not-B
handling aligned with Java
- Frequent items: is_empty() correct after purges
- t-digest: rank and quantile tails, merge min/max, iterator and
infinite-value fixes
- REQ: get_RSE() fixed; VarOpt: only positive weights accepted
- GCC 15 build fix, missing standard includes
Behavior changes will be listed in the release notes on GitHub after
the release.
*Source repository:*
- https://github.com/apache/datasketches-cpp
*Git Tag for this release:*
- https://github.com/apache/datasketches-cpp/releases/tag/5.3.0-rc1 on
branch 5.3.x
*Git HashId* for this release is: 5b5524f55d121225a7909c2851271327684585d7
*The Release Candidate Zip Repository:*
- https://dist.apache.org/repos/dist/dev/datasketches/cpp/5.3.0-rc1/
*The public signing key* can be found in the KEYS file:
- https://dist.apache.org/repos/dist/dev/datasketches/KEYS
*The artifacts have been signed with key: *--keyid-format SHORT : 8CD4A902
*Build & Test Guide:*
- https://github.com/apache/datasketches-cpp/blob/5.3.0-rc1/README.md
Note: the source zip no longer contains an empty build/ directory, so
for the Windows instructions run "mkdir build" first.
*The vote will be performed as follows:*
- This letter will be published on dev@ and remain open for at least 72
hours (excluding weekends and holidays), AND until at least 3 (+1) PMC
votes or
a majority of (+1) PMC votes are acquired.
- Anyone in the community can vote.
- This vote will close no earlier than Wednesday, Oct 7th 6PM PDT (Oct
8th 01:00 UTC)
Please vote accordingly:
[ ] +1 approve
[ ] +0 no opinion
[ ] -1 disapprove with the reason
Thank you,

Hi,
+1 (binding).
I verified the source release on macOS 26.6.2 ARM64 with Apple Clang
21 and CMake 4.4.3:
- SHA-512 checksum and PGP signature passed.
- Source files match the release tag, with the additional generated
git.properties recording the correct commit.
- The Release build and all 17 CTest suites passed.
- Installation and an independent C++11 consumer test passed.
I noticed three metadata and documentation issues: the LICENSE entry
for the separately downloaded Catch2 dependency, the NOTICE copyright
year, and the documented minimum CMake version.
I consider these non-blocking for this release and have opened [1] to
address them for the next release.

Best,
tison.

Checked:
- Signature is good; SHA-512 matches
- Source zip matches tag 5.3.0-rc1 (5b5524f5); only addition is
git.properties
- LICENSE and NOTICE present, third-party code listed in LICENSE,
no binaries
- Built and ran the unit tests on macOS 26.6.2 (25G83, Apple Silicon)
with Apple clang 21.0.0 and CMake 4.4.4: all 17 test suites pass
Thanks for doing the release!
