https://github.com/openssl/openssl/commits/ and pick the appropriate
release branch.
Changes between 1.1.1g and 1.1.1h [22 Sep 2020]
*) Certificates with explicit curve parameters are now disallowed in
verification chains if the X509_V_FLAG_X509_STRICT flag is used.
[Tomas Mraz]
*) The 'MinProtocol' and 'MaxProtocol' configuration commands now silently
ignore TLS protocol version bounds when configuring DTLS-based contexts, and
conversely, silently ignore DTLS protocol version bounds when configuring
TLS-based contexts. The commands can be repeated to set bounds of both
types. The same applies with the corresponding "min_protocol" and
"max_protocol" command-line switches, in case some application uses both TLS
and DTLS.
SSL_CTX instances that are created for a fixed protocol version (e.g.
TLSv1_server_method()) also silently ignore version bounds. Previously
attempts to apply bounds to these protocol versions would result in an
error. Now only the "version-flexible" SSL_CTX instances are subject to
limits in configuration files in command-line options.
[Viktor Dukhovni]
*) Handshake now fails if Extended Master Secret extension is dropped
on renegotiation.
[Tomas Mraz]
*) The Oracle Developer Studio compiler will start reporting deprecated APIs
Changes between 1.1.1f and 1.1.1g [21 Apr 2020]
*) Fixed segmentation fault in SSL_check_chain()

* This is important also because `BN_dup()` (and `BN_copy()`) do not
* propagate the `BN_FLG_CONSTTIME` flag from the source `BIGNUM`, and
* this brings an extra risk of inadvertently losing the flag, even when
* the caller specifically set it.
*
* The propagation has been turned on and off a few times in the past
* years because in some conditions has shown unintended consequences in
* some code paths, so at the moment we can't fix this in the BN layer.
*
* In `EC_KEY_set_private_key()` we can work around the propagation by
* manually setting the flag after `BN_dup()` as we know for sure that
* inside the EC module the `BN_FLG_CONSTTIME` is always treated
* correctly and should not generate unintended consequences.
*
* Setting the BN_FLG_CONSTTIME flag alone is never enough, we also have
* to preallocate the BIGNUM internal buffer to a fixed public size big
* enough that operations performed during the processing never trigger
* a realloc which would leak the size of the scalar through memory
* accesses.
*
* Fixed Length
* ------------
*
* The order of the large prime subgroup of the curve is our choice for
* a fixed public size, as that is generally the upper bound for
* generating a private key in EC cryptosystems and should fit all valid
* secret scalars.
*
* For preallocating the BIGNUM storage we look at the number of "words"
* required for the internal representation of the order, and we
* preallocate 2 extra "words" in case any of the subsequent processing
* might temporarily overflow the order length.
