Bugs fixed

Core

• box.cfg called with a non-table argument now fails with a clear cfg should be a table error instead of a confusing internal one (gh-13145).
• Deprecated box.cfg options set via TT_* environment variables are now translated to their replacement options, and the translation no longer silently overrides an explicitly provided value of a replacement option (gh-13144).
• Fixed a redundant deprecation warning about replication_connect_quorum being logged when bootstrap_strategy is set to 'legacy' explicitly in the same box.cfg call (gh-12933).

Replication

• Fixed an ordering bug in WAL batching that could make a joining replica miss rows written by the master (gh-11028).

LuaJIT

Backported patches from the vanilla LuaJIT trunk (gh-12480). The following issues were fixed as part of this activity:

• Fixed incorrect JIT behavior for vararg FFI functions on the macOS AArch64 platform (gh-6097).
• Fixed various FFI ABI and calling convention issues for x64/AArch64 architectures.
• Fixed ipairs_aux() to match JIT backend behavior on x86/x64.
• Fixed os.time() returning -1.
• Fixed UBSan warnings for table.new().

Lua

Fio

• The default permission mode for fio.open() was changed for newly created files to 0666 (before umask) (gh-7981).

Http client

• Fixed a regression of authorization on an HTTP proxy or a target HTTP(S) host using the Basic algorithm (gh-12805).

Datetime

• Fixed parsing for time with a decimal fraction of hour or minute (gh-12082).
• Fixed a stack overflow strptime() function when parsing timezones (ghs-146).

Pickle

• Fixed abortion on calling pack() with an empty format string or a string value for the 'a' format specifier (gh-12063).

Uri

• Fixed a Use-After-Poison crash in uri.format() caused by a long URI (ghs-151).
