This free Mac app. Download Malwarebytes for Mac (the free version) and you get a 14-day trial of the premium version with automatic (real-time) virus and malware protection. After 14 days, your trial reverts to a limited. ADWAREMEDIC is now MALWAREBYTES ANTI-MALWARE FOR MAC And, yes, it's still free. The 1.0.3 version of Adware Medic for Mac is available as a free download on our website. This Mac download was checked by our antivirus and was rated as virus free. This free Mac app was originally developed by Dybala Securities. I will, however, highly recommend adware medic. Adware is pretty much the only thing you can get on Mac that is somewhat common and even then, its only usually browser stuff and non malicious.

Release Highlights
- IANA Data 2020d
JDK 8u281 contains IANA time zone data version 2020d. For more information, refer to Timezone Data Versions in the JRE Software. - New Feature: groupname Option Added to keytool Key Pair Generation
A new-groupname
option has been added tokeytool -genkeypair
so that a user can specify a named group when generating a key pair. For example,keytool -genkeypair -keyalg EC -groupname secp384r1
will generate an EC key pair by using thesecp384r1
curve. Because there might be multiple curves with the same size, using the-groupname
option is preferred over the-keysize
option.
See JDK-8213400 - New Feature: Apache Santuario Library Updated to Version 2.1.4
The Apache Santuario library has been upgraded to version 2.1.4. As a result, a new system propertycom.sun.org.apache.xml.internal.security.parser.pool-size
has been introduced.
This new system property sets the pool size of the internalDocumentBuilder
cache used when processing XML Signatures. The function is equivalent to theorg.apache.xml.security.parser.pool-size
system property used in Apache Santuario and has the same default value of 20.
See JDK-8231507 - New Feature: Support for certificate_authorities Extension
The 'certificate_authorities' extension is an optional extension introduced in TLS 1.3. It is used to indicate the certificate authorities (CAs) that an endpoint supports and should be used by the receiving endpoint to guide certificate selection.
See JDK-8206925 - Other notes: Changed Properties.loadFromXML to Comply with Specification
The implementation of thejava.util.Properties loadFromXML
method has been changed to comply with its specification. Specifically, the underlying XML parser implementation now rejects non-compliant XML documents by throwing anInvalidPropertiesFormatException
as specified by theloadFromXML
method.
See JDK-8213325 - Other notes: US/Pacific-New Zone Name Removed as Part of tzdata2020b.
Following the JDK's update to tzdata2020b, the long-obsolete files namedpacificnew
andsystemv
have been removed. As a result, the 'US/Pacific-New' Zone name declared in thepacificnew
data file is no longer available for use.
