the callsite does not require cryptographic security. + Introduce the "insecure" mode and use it appropriately. + (merge 0b4f8afef6 ps/reftable-get-random-fix later to maint). + + * A misconfigured "fsck.skiplist" configuration variable was not + diagnosed as an error, which has been corrected. + (merge ca7158076f jt/fsck-skiplist-parse-fix later to maint). + + * Extended SHA-1 expression parser did not work well when a branch + with an unusual name (e.g. "foo{bar") is involved. + (merge 191f0c8db2 en/object-name-with-funny-refname-fix later to maint). + + * The meson build procedure looked for the 'version-def.h' file in a + wrong directory, which has been corrected. + (merge 4771501c0a tc/meson-use-our-version-def-h later to maint). + + * The meson build procedure for Documentation/technical/ hierarchy was + missing necessary dependencies, which has been corrected. + (merge 1dca492edd sj/meson-doc-technical-dependency-fix later to maint). + + * The "instaweb" bound only to local IP address without "--local" and + to all addresses with "--local", which was the other way around, when + using Python's http.server class, which has been corrected. + (merge 76baf97fa1 ak/instaweb-python-port-binding-fix later to maint). + + * Document that it is insecure to use Personal Access Tokens, which + some hosting providers take as username/password, embedded in URLs. + (merge a90ff409f0 mh/doc-credential-helpers-with-pat later to maint). + + * The help text from "git $cmd -h" appear on the standard output for + some $cmd and the standard error for others.
