 Check out the git tag OTP-21.1.2, 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.

 ---------------------------------------------------------------------
 --- compiler-7.2.7 --------------------------------------------------
 ---------------------------------------------------------------------

 The compiler-7.2.7 application can be applied independently of other
 applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15353    Application(s): compiler
               Related Id(s): ERL-753

               Fixed a bug where incorrect code was generated
               following a binary match guard.


 Full runtime dependencies of compiler-7.2.7: crypto-3.6, erts-9.0,
 hipe-3.12, kernel-4.0, stdlib-2.5


 ---------------------------------------------------------------------
 --- erts-10.1.2 -----------------------------------------------------
 ---------------------------------------------------------------------

 Note! The erts-10.1.2 application can *not* be applied independently
       of other applications on an arbitrary OTP 21 installation.

       On a full OTP 21 installation, also the following runtime
       dependency has to be satisfied:
       -- kernel-6.1 (first satisfied in OTP 21.1)


 --- Fixed Bugs and Malfunctions ---

  OTP-15421    Application(s): erts

               Fixed a rare bug where files could be closed on a
               normal instead of an IO scheduler, resulting in system
               instability if the operation blocked.


 Full runtime dependencies of erts-10.1.2: kernel-6.1, sasl-3.0.1,
 stdlib-3.5


 ---------------------------------------------------------------------
 --- public_key-1.6.3 ------------------------------------------------
 ---------------------------------------------------------------------

 The public_key-1.6.3 application can be applied independently of
 other applications on a full OTP 21 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-15367    Application(s): public_key

               Add DSA SHA2 oids in public_keys ASN1-spec and
               public_key:pkix_sign_types/1


 Full runtime dependencies of public_key-1.6.3: asn1-3.0, crypto-3.8,
 erts-6.0, kernel-3.0, stdlib-3.5
