+Apache source releases
++ Burr is an Apache Software Foundation project. The source release + is the official artifact voted on by the IPMC; per the{" "} + + ASF release policy + + , the wheel and sdist below are the same bits published to PyPI. + If you're packaging Burr for redistribution, or you simply + prefer to build from source, start here. +
+ ++ Latest +
++ Previous +
++ Older releases live in the{" "} + + ASF archive + + . +
+Verifying a release
+
+ If you're downloading source releases above, you{" "}
+ should verify
+ them before use. The PGP signature (
+ .asc) proves the
+ release was signed by an Apache Burr release manager; the SHA-512
+ checksum (.sha512)
+ detects transmission corruption.
+
1. Import the KEYS file
+
+ The KEYS file holds the public PGP keys of all Apache Burr
+ release managers, served from{" "}
+ downloads.apache.org:
+
+ {`curl -O ${KEYS_URL}
+gpg --import KEYS`}
+
+
+ 2. Verify the signature
+
+ {`gpg --verify apache-burr-${LATEST.version}-incubating-src.tar.gz.asc \\
+ apache-burr-${LATEST.version}-incubating-src.tar.gz`}
+
+ + Look for "Good signature from ..." in the output. A + warning that the key is not certified by a trusted signature is + expected unless you've set up a web of trust — what matters + is that the fingerprint matches one in KEYS. +
+ +3. Verify the checksum
+
+ {`sha512sum -c apache-burr-${LATEST.version}-incubating-src.tar.gz.sha512`}
+
+
+ On macOS, use{" "}
+ shasum -a 512 -c{" "}
+ instead of sha512sum -c
+ .

+ Apache Burr (Incubating) is an effort undergoing incubation at + The Apache Software Foundation (ASF), sponsored by the Apache + Incubator. Incubation is required of all newly accepted projects + until a further review indicates that the infrastructure, + communications, and decision making process have stabilized in a + manner consistent with other successful ASF projects. While + incubation status is not necessarily a reflection of the + completeness or stability of the code, it does indicate that the + project has yet to be fully endorsed by the ASF. +
