- Update to 21.1.2:
* diameter: An inadvertently removed monitor in diameter 2.1
caused the ets table diameter_reg to leak entries, and caused
service restart and more to fail.
* erts: Fixed bug that could cause a VM crash when a corrupt
message is received on distribution channel from other node.
- Update to 20.1.1:
* compiler: The compiler could issue an incorrect internal
consistency failure diagnostic for some complicated bit syntax
maches.
* erts: The new zlib module returned a data_error when inflating
concatenated streams, which was incompatible with the old
module's behavior of returning the uncompressed data up to the
end of the first stream.
* erts: zlib:gunzip/1 will no longer stop at the end of the first
stream when decompressing concatenated gzip files.
* ssh: Fixed broken printout
* ssh: Disable aes_gcm ciphers if peer is OpenSSH 6.2 which is
known to have trouble with them in some cases.
- Update to 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). Everything is enabled by default to match
the old behavior, but specific categories can be toggled at
will with minimal runtime overhead when disabled. Refer to the
documentation on lcnt:rt_mask/1 for details.
* lcnt:collect and lcnt:clear will no longer block all other
threads in the runtime system. This makes it possible to run
the lock counting under heavier load.
* 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. The
added functions are: enif_ioq_create(), enif_ioq_destroy(),
enif_ioq_enq_binary(), enif_ioq_enqv(), enif_ioq_deq(),
enif_ioq_peek(), enif_inspect_iovec(), enif_free_iovec()
* 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. See the
reference manual and the SSH User's Guide chapter "Configuring
algorithms in SSH".
* 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.
Previous behaviour was to report each contributing entry
separately.
