Version Description
- Released on 6/6/2016
- Added Google Play Music to subscribe page shortcode embed and sidebar widget.
- Added Stitcher to subscribe page shortcode embed and sidebar widget.
- New: Strict Category Podcasting. Select a specific category to each episode for statistics tracking and subscription links.
- New: Podcast only category feeds. You can now mix blog posts with podcast episodes in your podast categories.
- New: Blubrry Audio Player. Modern podcast audio player complete with subscribe and share tools. For Blubrry Hosting customers only.
- Updated the getid3 library to latest version.
- Embed link enhanced to use provided embed. If an embed is placed into an episode, the embed link below the player will use that embed as well.
- Fixed bug where post type podcast feed with slug 'podcast' will also get the default podcast feed settings (Thanks steveportigal for bringing to our attention).
- Fixed bug with WP 4.5 dropping the
rss-httpcontent type "text/xml". - Added shortcode attribute
ids=""so you can specify post IDs for the playlist player to display exclusively. (Thanks John Haspel for the feature suggestion!) - RSS import now sets the blog post content from the iTunes summary if no description or content:encoded was found in the feed. (Thanks @synthtony for letting us know about the situation)
- RSS import function calls to
mb_stripos()will fallback tostripos()if the PHP mb (Multibyte String) library not available. (Thanks Glen Donohu for bringing to our attention!) - Import to podcast category option added.
- Added audio ac3 and dts to media detection getid3 library (these are not podcast safe formats though we can detect their meta information).
- Improved logic for setting the iTunes subtitle and iTunes summary from blog post excerpts and blog post content if no custom iTunes summary and/or subtitle is set.
- Improved feed logic to minimize SQL queries
- Feed Maximizer option now applies to category podcast only feeds.
- Renamed "Appearance" settings to "Website" settings
- Added "Destination" settings for podcast directories and apps
- You can now select from pages when setting your Subscribe Page.
- Changed labels for Podcasting SEO guidance to include word "Podcasting" so not to confuse with "Web SEO".
- Updated Podcasting SEO guidance to reflect how search works in Google Play Music (Thanks Daniel Lewis for confirming what is indexed!)
- Changed wording for Podcasting SEO guidance with Author field, replaced "slogans" with "nicknames" so it is more clear that we mean slogans for talent on the show.
- Removed logic to fallback to the HTML5 player for mobile devices. This was only needed when Flash based players were used.
- Quicktime Embed option for m4a audio removed due to security concerns with Quicktime.
- SWF embed support dropped.
- Embed link now toggles embed box when clicked multiple times.
- ATTENTION: The 1 pixel out audio player will be removed from PowerPress 7.1.

ISO Language Codes - http://www.loc.gov/standards/iso639-2/php/code_list.php
|
| 1741 |
+
Because the language codes specified by ISO 639-2/T are three characters long, they must be packed to fit into a 16-bit field.
|
| 1742 |
+
The packing algorithm must map each of the three characters, which are always lowercase, into a 5-bit integer and then concatenate
|
| 1743 |
+
these integers into the least significant 15 bits of a 16-bit integer, leaving the 16-bit integer's most significant bit set to zero.
|
| 1744 |
+
|
| 1745 |
+
One algorithm for performing this packing is to treat each ISO character as a 16-bit integer. Subtract 0x60 from the first character
|
| 1746 |
+
and multiply by 2^10 (0x400), subtract 0x60 from the second character and multiply by 2^5 (0x20), subtract 0x60 from the third character,
|
| 1747 |
+
and add the three 16-bit values. This will result in a single 16-bit value with the three codes correctly packed into the 15 least
|
| 1748 |
+
significant bits and the most significant bit set to zero.
