An additional extension to MPEG-2 is named MPEG-2.5 audio, as MPEG-3 already had a different meaning. This extension was developed at Fraunhofer IIS, the registered MP3 patent holders. Like MPEG-2, MPEG-2.5 adds new sampling rates exactly half of that previously possible with MPEG-2. It thus widens the scope of MP3 to include human speech and other applications requiring only 25% of the frequency reproduction possible with MPEG-1. While not an ISO recognized standard, MPEG-2.5 is widely supported by both inexpensive and brand name digital audio players as well as computer software based MP3 encoders and decoders. A sample rate comparison between MPEG-1, 2 and 2.5 is given further down. MPEG-2.5 was not developed by MPEG and was never approved as an international standard. MPEG-2.5 is thus an unofficial or proprietary extension to the MP3 format.

Gorbachev again refused to make any changes to the status of Nagorno Karabakh, which remained part of Azerbaijan. Instead he sacked both Republics' Communist Party Leaders: On May 21, 1988, Karen Demirchian was replaced by Suren Harutyunyan as First Secretary of the Communist Party of Armenia. However, Harutyunyan quickly decided to run before the nationalist wind and on May 28, allowed Armenians to unfurl the red-blue-gold First Armenian Republic flag for the first time in almost 70 years. On June 15, 1988, the Armenian Supreme Soviet adopted a resolution formally approving the idea of Nagorno Karabakh joining Armenia. Armenia, formerly one of the most loyal Republics, had suddenly turned into the leading rebel republic. On July 5, 1988, when a contingent of troops was sent in to remove demonstrators by force from Yerevan's Zvartnots International Airport, shots were fired and one student protester was killed. In September, further large demonstrations in Yerevan led to the deployment of armored vehicles. In the autumn of 1988 almost all the 200,000 Azerbaijani minority in Armenia was expelled by Armenian Nationalists, with over 100 killed in the process – this, after the Sumgait pogrom earlier that year carried out by Azerbaijanis against ethnic Armenians and subsequent expulsion of all Armenians from Azerbaijan. On November 25, 1988, a military commandant took control of Yerevan as the Soviet government moved to prevent further ethnic violence.
Who had been previously removed from Azerbaijan?

The most famous passage in Burke's Reflections was his description of the events of 5–6 October 1789 and the part of Marie-Antoinette in them. Burke's account differs little from modern historians who have used primary sources. His use of flowery language to describe it, however, provoked both praise and criticism. Philip Francis wrote to Burke saying that what he wrote of Marie-Antoinette was "pure foppery". Edward Gibbon, however, reacted differently: "I adore his chivalry". Burke was informed by an Englishman who had talked with the Duchesse de Biron, that when Marie-Antoinette was reading the passage, she burst into tears and took considerable time to finish reading it. Price had rejoiced that the French king had been "led in triumph" during the October Days, but to Burke this symbolised the opposing revolutionary sentiment of the Jacobins and the natural sentiments of those who shared his own view with horror—that the ungallant assault on Marie-Antoinette—was a cowardly attack on a defenceless woman.
