Check out the git tag OTP-27.1, and build a full OTP system including
documentation. Apply one or more applications from this build as patches to your
installation using the 'otp_patch_apply' tool. For information on install
requirements, see descriptions for each application version below.

HIGHLIGHTS

The zip module has been updated with support for:
- zip64 archives - Archives larger than 4GB or with more than 2^32 entries.
- extended timestamps - Higher resolution and in UTC.
- UID/GID - Save and extract the original UID/GID.
- Fixes so that permission mode attributes are correctly read and set for
  files in archives.
- zip:list_dir/2 now also returns directories, not only files. (You can
  disable this behaviour by using the option skip_directories).
Various bugs in the original implementation have also been fixed, such as:
- Correctly encode and decode the DOS timestamps for entries within an archive
  (that is the non-extended timestamp).
- Fix DOS timestamps to be set to localtime instead of UTC (use extended
  timestamps for UTC timestamps).
- Use the unix file attributes read from disk when creating archives instead
  of setting everything to 644.

The otp_patch_apply script, used for patching OTP applications, has been
fixed. It was not possible (and still is not possible) to apply applications
from the OTP 27.0.1 patch package onto an OTP 27.0 installation.
Own Id: OTP-19182
./otp_build download_ex_doc was using sha1sum and sha256sum which work
on various Unix systems. macOS does not have these applications installed by
default, so we added a new dependency to the build process, shasum, which is
installed by default on macOS and allows us to check the integrity of
ex_doc.

Deprecation of RSA encryption functions has been reverted, as there still
exists legitimate use cases with other padding modes than PKCS-1.
While use PCKS-1 padding with some versions of cryptolib could be considered

oracle attacks.

Improvements and New Features

Deprecation of RSA encryption functions has been reverted, as there still
exists legitimate use cases with other padding modes than PKCS-1.
While use PCKS-1 padding with some versions of cryptolib could be considered
secure, we still recommend using other algorithms that are less sensitive to
oracle attacks.

It is now possible to use a verification fun of arity 4, giving the user fun
access to both encoded and decoded versions of the certificate. This is
desirable as a workaround for encoding errors preventing re-encoding from
being reliable. This also saves some work load if the encoded version is
needed.
Note that calling public_key:pkix_path_validation/3 with only decoded certs
is not recommended, due to the decoding workarounds, although it will work as
long as the workarounds are not needed.
If the decoded version is needed before thecall to public_key it is
recommend to use the combined_cert- type to avoid double decoding. Note that
the path validation algorithm itself always needs both the encoded and decoded
versions of the certs.
The ssl implementation will now benefit from using this function instead of
emulating the verify_fun/4.

The parser was incorrectly parsing formatted markdown (either bold or italics)

Option. to appear in italics.
The markdown parser is also used in the creation of other documentation

*** POTENTIAL INCOMPATIBILITY ***
The zip module has been updated with support for:
- zip64 archives - Archives larger than 4GB or with more than 2^32 entries.
- extended timestamps - Higher resolution and in UTC.
- UID/GID - Save and extract the original UID/GID.
- Fixes so that permission mode attributes are correctly read and set for
  files in archives.
- zip:list_dir/2 now also returns directories, not only files. (You can
  disable this behaviour by using the option skip_directories).
Various bugs in the original implementation have also been fixed, such as:
- Correctly encode and decode the DOS timestamps for entries within an archive
  (that is the non-extended timestamp).
- Fix DOS timestamps to be set to localtime instead of UTC (use extended
  timestamps for UTC timestamps).
- Use the unix file attributes read from disk when creating archives instead
  of setting everything to 644.
