Functionality added or changed

Build

Support fedora-35 build (gh-6692).

Bugs fixed

Core

Fixed a crash that could happen in case a tuple is deleted from a functional index while there is an iterator pointing to it (gh-6786).
Fixed memory leak in interactive console (gh-6817).
Fixed an assertion fail when passing tuple without primary key fields to before_replace trigger. Now tuple format is checked before execution of before_replace triggers and after each one (gh-6780).
Banned DDL operations in space on_replace triggers, since they could lead to a crash (gh-6920).
Fixed a bug due to which all fibers created with fiber_attr_setstacksize() leaked until the thread exit. Their stacks also leaked except when fiber_set_joinable(..., true) was used.

Vinyl

Immediate removal of compacted run files created after the last checkpoint optimization now works for replica’s initial JOIN stage (gh-6568).
Fixed crash during recovery of a secondary index in case the primary index contains incompatible phantom tuples (gh-6778).

Raft

Reconfiguration of box.cfg.election_timeout could lead to a crash or undefined behaviour if done during an ongoing election with a special WAL write in progress.

LuaJIT

Fixed top part of Lua stack (red zone, free slots, top slot) unwinding in lj-stack command.
Added the value of g->gc.mmudata field to lj-gc output.
string.char() builtin recording is fixed in case when no arguments are given (gh-6371, gh-6548).
Actually made JIT respect maxirconst trace limit while recording (gh-6548).

Lua

Fixed table.equals result when booleans compared (gh-6386).
Tap subtests inherit strict mode from parent (gh-6868).

Box

Added iterator type checking and allow to pass iterator as a box.index.{ALL,GT,…} directly (gh-6501).

HTTP client

Fixed invalid headers after redirect (gh-6101).

Recovery

When force_recovery cfg option is set, Tarantool is able to boot from snap/xlog combinations where xlog covers changes committed both before and after snap creation. For example, 0...0.xlog, covering everything up to vclock {1: 15} and 0...09.snap, corresponding to vclock {1: 9} (gh-6794).
