The service release contains mostly bug fixes and characteristics<br>
improvements but also some new features.<br>
<br>
Some highlights for 20.1<br>
<br>
crypto, public_key: Extend crypto and public_key functions sign and<br>
verify with:<br>
support for RSASSA-PS padding for signatures and for<br>
saltlength setting<br>
X9.31 RSA padding.<br>
sha, sha224, sha256, sha384, and sha512 for dss<br>
signatures as mentioned in NIST SP 800-57 Part 1.<br>
ripemd160 to be used for rsa signatures.<br>
<br>
A new tuple in crypto:supports/0 reports supported MAC<br>
algorithms.<br>
<br>
diameter:<br>
Add service option decode_format to allow incoming messages to<br>
be decoded into maps<br>
instead of records.<br>
Decode performance has been improved.<br>
Add service/transport option avp_dictionaries to give better<br>
support for dictionaries only defining AVPs.<br>
<br>
erts: Upgraded the ERTS internal PCRE library from version 8.40 to<br>
version 8.41.<br>
<br>
erts, kernel, tools: Profiling with lock counting can now be fully<br>
toggled at runtime in<br>
the lock counting emulator (-emu_type lcnt). Everything<br>
is enabled by default to match the old behavior, but<br>
specific categories can be toggled at will with minimal<br>
runtime overhead when disabled. Refer to the<br>
documentation on lcnt:rt_mask/1 for details.<br>
<br>
lcnt:collect and lcnt:clear will no longer block all<br>
other threads in the runtime system. This makes it possible to run<br>
the lock counting<br>
under heavier load.<br>
<br>
erts: The zlib module has been refactored and all its operations<br>
will now yield appropriately,<br>
allowing them to be used freely in concurrent applications.<br>
<br>
erts, tools: Add erlang:iolist_to_iovec/1, which converts an<br>
iolist() to an erlang:iovec(), which is suitable for use<br>
with enif_inspect_iovec().<br>
<br>
erts: Add new nif API functions for managing an I/O Queue.<br>
The added functions are: enif_ioq_create(), enif_ioq_destroy(),<br>
enif_ioq_enq_binary(),<br>
enif_ioq_enqv(), enif_ioq_deq(), enif_ioq_peek(),<br>
enif_inspect_iovec(), enif_free_iovec()<br>
<br>
observer/crashdump_viewer:<br>
Reading of crash dumps with many binaries is optimized.<br>
A progress bar is shown when the detail view for a process is<br>
opened.<br>
The cdv script now sets ERL_CRASH_DUMP_SECONDS=0 to<br>
avoid generating a new crash dump from the node running the<br>
Crashdump Viewer.<br>
<br>
observer:<br>
Add system statistics and limits to frontpage in<br>
observer.<br>
<br>
public_key, ssl**:<br>
Improved error propagation and reports<br>
<br>
ssh: A new option modify_algorithms is implemented. It<br>
enables specifying changes on the default algorithms<br>
list. See the reference manual and the SSH User's Guide<br>
chapter "Configuring algorithms in SSH".<br>
<br>
tools/xref: The predefined Xref analysis locals_not_used now<br>
understands<br>
the -on_load() attribute and does not report unused functions.<br>
<br>
tools/fprof: When sampling multiple processes and analyzing<br>
with totals set to true, the output now sums together<br>
all caller and callee entries which concerns the same<br>
function. Previous behaviour was to report each<br>
contributing entry separately.<br>
