Some highlights for 20.1:
- crypto, public_key: Extend crypto and public_key functions sign and
verify with:
- support for RSASSA-PS padding for signatures and for saltlength
setting
- X9.31 RSA padding.
- sha, sha224, sha256, sha384, and sha512 for dss signatures as
mentioned in NIST SP 800-57 Part 1.
- ripemd160 to be used for rsa signatures.
- A new tuple in crypto:supports/0 reports supported MAC algorithms.
- diameter:
- Add service option decode_format to allow incoming messages to be
decoded into maps instead of records.
- Decode performance has been improved.
- Add service/transport option avp_dictionaries to give better
support for dictionaries only defining AVPs.
- erts: Upgraded the ERTS internal PCRE library from version 8.40 to
version 8.41.
- erts, kernel, tools: Profiling with lock counting can now be fully
toggled at runtime in the lock counting emulator (-emu_type lcnt).
- erts: The zlib module has been refactored and all its operations
will now yield appropriately, allowing them to be used freely in
concurrent applications.
- erts, tools: Add erlang:iolist_to_iovec/1, which converts an
iolist() to an erlang:iovec(), which is suitable for use with
enif_inspect_iovec().
- erts: Add new nif API functions for managing an I/O Queue.
- observer/crashdump_viewer:
- Reading of crash dumps with many binaries is optimized.
- A progress bar is shown when the detail view for a process is
opened.
- The cdv script now sets ERL_CRASH_DUMP_SECONDS=0 to avoid
generating a new crash dump from the node running the Crashdump
Viewer.
- observer: Add system statistics and limits to frontpage in observer.
- public_key, ssl**: Improved error propagation and reports
- ssh: A new option modify_algorithms is implemented. It enables
specifying changes on the default algorithms list.
- tools/xref: The predefined Xref analysis locals_not_used now
understands the -on_load() attribute and does not report unused
functions.
- tools/fprof: When sampling multiple processes and analyzing with
totals set to true, the output now sums together all caller and
callee entries which concerns the same function.
